warning! safety first
The following safety warnings must be observed at all times:
■ Due to the complexity of this system, installation of this product must only be performed by an authorized
DEI dealer.
■ When properly installed, this system can start the vehicle via a command signal from the remote control
transmitter. Therefore, never operate the system in an area that does not have adequate ventilation. The following precautions are the sole responsibility of the user; however, authorized DEI dealers should make the
following recommendations to all users of this system:
1. Never operate the system in an enclosed or partially enclosed area without ventilation (such as a garage).
2. When parking in an enclosed or partially enclosed area or when having the vehicle serviced, the remote
start system must be disabled using the installed toggle switch.
3. It is the user's sole responsibility to properly handle and keep out of reach from children all remote
control transmitters to assure that the system does not unintentionally remote start the vehicle.
4. THE USER MUST INSTALL A CARBON MONOXIDE DETECTOR IN OR ABOUT THE LIVING AREA ADJACENT
TO THE VEHICLE. ALL DOORS LEADING FROM ADJACENT LIVING AREAS TO THE ENCLOSED OR PARTIALLY ENCLOSED VEHICLE STORAGE AREA MUST AT ALL TIMES REMAIN CLOSED.
■ Use of this product in a manner contrary to its intended mode of operation may result in property damage,
personal injury, or death. Except when performing the Safety Check outlined in this installation guide, (1)
Never remotely start the vehicle with the vehicle in gear, and (2) Never remotely start the vehicle with the
keys in the ignition. The user will be responsible for having the neutral safety feature of the vehicle periodically checked, wherein the vehicle must not remotely start while the car is in gear. This testing should be
performed by an authorized DEI dealer in accordance with the Safety Check outlined in this product installation guide. If the vehicle starts in gear, cease remote start operation immediately and consult with the user
to fix the problem immediately.
■ After the remote start module has been installed, test the remote start module in accordance with the Safety
Check outlined in this installation guide. If the vehicle starts when performing the Neutral Safety Shutdown
Circuit test, the remote start unit has not been properly installed. The remote start module must be removed
or properly reinstalled so that the vehicle does not start in gear. All installations must be performed by an
authorized DEI dealer. OPERATION OF THE REMOTE START MODULE IF THE VEHICLE STARTS IN GEAR IS CONTRARY TO ITS INTENDED MODE OF OPERATION. OPERATING THE REMOTE START SYSTEM UNDER THESE
CONDITIONS MAY RESULT IN PROPERTY DAMAGE OR PERSONAL INJURY. IMMEDIATELY CEASE THE USE OF
THE UNIT AND REPAIR OR DISCONNECT THE INSTALLED REMOTE START MODULE. DEI WILL NOT BE HELD
RESPONSIBLE OR PAY FOR INSTALLATION OR REINSTALLATION COSTS.

installation points to remember
IMPORTANT! This product is designed for fuel-injected, automatic transmission vehicles only.
Installing it in a standard transmission vehicle is dangerous and is contrary to its intended use.
Before beginning the installation:
■ Please read this entire installation guide before beginning the installation. The installation of this remote
start system requires interfacing with many of the vehicle’s systems. Many new vehicles use low-voltage or
multiplexed systems that can be damaged by low resistance testing devices, such as test lights and logic
probes (computer safe test lights). Test all circuits with a high quality digital multi-meter before making connections.
■ Do not disconnect the battery if the vehicle has an anti-theft-coded radio. If equipped with an air bag, avoid
disconnecting the battery if possible. Many airbag systems will display a diagnostic code through their
warning lights after they lose power. Disconnecting the battery requires this code to be erased, which can
require a trip to the dealer.
■ Remove the domelight fuse. This prevents accidentally draining the battery.
■ Roll down a window to avoid being locked out of the vehicle.
After the installation:
■ Test all functions. The "Using Your System" section of the Owner's Guide is very helpful when testing.
■ Complete the vehicle Safety Check outlined in this manual prior to the vehicle reassembly.

finding the wires you need
IMPORTANT! Do not use a 12V test light or logic probe (computer safe test light) to locate these
wires! All testing described in this manual assumes the use of a digital multimeter.
obtaining constant 12V
We recommend two possible sources for 12V constant: The (+) terminal of the battery, or the constant 12V supply
to the ignition switch. Always install a fuse within 12 inches of this connection. If the fuse will also be powering other circuits, such as door locks, a power window module, or a Nite-Lite headlight control system, fuse
accordingly.
IMPORTANT! Do not remove the fuse holder on the red wire. It ensures that the control module has
its own fuse, of the proper value, regardless of how many accessories are added to the main power feed.
finding the starter wire
The starter wire provides 12V directly to the starter or to a relay controlling starter. In some vehicles, it is
necessary to power a cold start circuit. A cold start circuit will test exactly like a starter circuit, but it does not
control the starter. Instead, the cold start circuit is used to prime the fuel injection system for starting when the
vehicle is cold.
How to find the starter wire with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the starter wire. The steering
column is an excellent place to find this wire. Remember you do not
need to interrupt the starter at the same point you test it. Hiding
your starter kill relay and connections is always recommended.
4. Turn the ignition key switch to the start position. Make sure the car
is not in gear! If your meter reads (+)12V, go to the next step. If it doesn’t, probe another wire.
6
© 2000 Directed Electronics, Inc. Vista, CA
5. Cut the wire you suspect of being the starter wire.
6. Attempt to start the car. If the starter engages, reconnect it and go back to Step 3. If the starter does not
turn over, you have the right wire.
finding the 12V switched ignition wire
The ignition wire is powered when the key is in the run or start position. This is because the ignition wire powers
the ignition system (spark plugs, coil) as well as the fuel delivery system (fuel pump, fuel injection computer).
Accessory wires lose power when the key is in the start position to make more current available to the starter motor.
How to find (+)12V ignition with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the ignition wire. The steering
column harness or ignition switch harness is an excellent place to find
this wire.
4. Turn the ignition key switch to the run position. If your meter reads
(+)12V, go to the next step. If it does not read (+)12V, probe another wire.
5. Now turn the key to the start position. The meter display should stay
steady, not dropping by more than a few tenths of a volt. If it drops close
to or all the way to zero, go back to Step 3. If it stays steady at (+)12V, you have found an ignition wire.
finding the accessory wire
An accessory wire will show (+)12V when the key is in the accessory and run positions. It will not show (+)12V
during the cranking cycle. There will often be more than one accessory wire in the ignition harness. The correct
accessory wire will power the vehicle's climate control system. Some vehicles may have separate wires for the
blower motor and the air conditioning compressor. In such cases, it will be necessary to add a relay to power the
second accessory wire.
finding a (+) parking light wire
Most vehicles use a (+) parking light circuit. The (+) parking light wire is often found near the light switch. In
many vehicles the light switch is built into the turn signal lever; in these vehicles the parking light wire can be
found in the steering column. The same wire can often be accessed in the kick panel or running board.
NOTE: Many Toyotas and other Asian vehicles, send a (-) signal from the switch to a relay. The
relay then sends (+)12V to the bulbs. Whenever you have difficulty finding a (+) parking light wire
near the switch, simply test the wires at any switch or control panel that is lit by the instrument
panel lighting. Remember, you need a (+) parking light wire that does not vary with the dimmer
setting.

7
How to find a (+) parking light flash wire with your multimeter:
1. Set to DCV or DC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Probe the wire you suspect of being the parking light wire. Usually, the area near the headlight/parking light
switch is an excellent area to start, as is the kick panel.
4. Turn on the parking lights. If your meter shows (+)12V, turn off the parking lights and make sure it goes back
to zero.
5. If it does return to zero, turn the parking lights back on and, using the dash light dimmer control, turn the
brightness of the dash lights up and down. If the meter changes more than a volt when using the dimmer,
look for another wire. If it stays relatively close to (+)12V, you have found your parking light wire.
NOTE: Vehicles that use a (-) signal from the switch to the factory relay may be interfaced directly.
(See H1/5 WHITE wire of Primary Harness (H1) Wire Connection Guide section.)
finding the tachometer wire
To test for a tachometer wire, a multimeter capable of testing AC voltage must be used. The tachometer wire will
show between 1V and 6V AC. In multi-coil ignition systems, the system can learn individual coil wires. Individual
coil wires in a multi-coil ignition system will register lower amounts of AC voltage. Also, if necessary, the system
can use a fuel injector control wire for engine speed sensing. Common locations for a tachometer wire are the
ignition coil itself, the back of the gauges, engine computers, and automatic transmission computers.
IMPORTANT! Do not test tachometer wires using a test light or logic probe. The vehicle will be
damaged.
How to find a tachometer wire with your multimeter:
1. Set to ACV or AC voltage (12V or 20V is fine).
2. Attach the (-) probe of the meter to chassis ground.
3. Start and run the vehicle.
4. Probe the wire you suspect of being the tachometer wire with the red probe of the meter.
5. If this is the correct wire the meter will read between 1V and 6V.

finding the wait-to-start bulb wire for diesels
In diesel vehicles it is necessary to interface with the wire that turns on the WAIT-TO-START light in the dashboard. This wire illuminates the bulb until the vehicle’s glow plugs are properly heated. When the light goes out
the vehicle can be started. This wire is always available at the connector leading to the bulb in the dashboard.
It can also be found at the Engine Control Module (ECM) in many vehicles.
To test and determine the polarity of this wire:
1. Set your multimeter to DCV or DC voltage (12 or 20V is fine).
2. Attach the (+) probe of the meter to (+)12V.
3. Probe the wire that you suspect leads to the bulb with the (-) probe of the meter.
4. Turn the ignition switch to the ON position.
5. If the meter indicates 12 volts until the light goes out you have isolated the correct wire and the wire's polarity is negative (ground while the bulb is on).
6. If the meter reads zero volts until the light goes out and then reads 12 volts, you have isolated the correct
wire and the wire's polarity is positive.

primary harness (H1) wire connection guide
H1/1 BLACK (-) chassis ground connection
Remove any paint and connect this wire to bare metal, preferably with a factory bolt rather than your own screw.
(Screws tend to either strip or loosen with time.) We recommend grounding all your components to the same
point in the vehicle.
H1/2 WHITE/BLUE (-) activation input
Sending a negative pulse to this wire will initiate the remote start sequence. This wire can be connected to an
auxiliary channel output of a security or keyless entry system or to an optional momentary switch to activate the
remote start system.
H1/3 LIGHT GREEN/BLACK (-) factory security disarm/special accessory output
This wire sends a negative pulse every time the remote start is activated. This can be used to pulse the disarm
wire of the vehicle's factory anti-theft device. Use a relay to send a (-) or (+) pulse to the disarm wire as shown
in the following diagrams. This wire can also be used as a special accessory output. (See Feature Descriptions
section of this guide.)

Relay for Negative (-) Disarm Wire
Relay for Positive (+) Disarm Wire
H1/4 YELLOW (+) ignition output to RF system
As a stand-alone system: The H1/4 YELLOW wire should not be connected to anything.
As an add-on car starter: If connected, disconnect the ignition/accessory input of the remote controlled security or keyless entry system. Connect the H1/4 YELLOW ignition output to the ignition/accessory input of the
remote controlled security or keyless entry system. This DEI system will prevent the host system from sensing
that the ignition is on during remote start operation.
H1/5 WHITE (-) light flash output
This wire provides a (-) 200mA output to flash the parking lights during remote start operation. This is suitable
for driving (-) light control wires in Toyota, Lexus, BMW, some Mitsubishi, some Mazda models, etc. If the vehicle
has a positive parking light circuit a relay must be used to flash the parking lights.

H1/6 GRAY/BLACK (-) diesel wait-to-start bulb input
Connect this wire to the wire in the vehicle that sends the signal to turn on the WAIT-TO-START bulb in the dashboard. In most diesels the wire is negative (ground turns on the bulb) and the GRAY/BLACK can be directly
connected to the wire in the vehicle. If the vehicle uses a positive wire (12V to turn on the bulb) a relay must
be used to change the polarity. (See Finding the Wires You Need section for testing procedures.) Here are some
common colors of this wire:
■ Chevrolet and GMC trucks: Light Blue or Dark Blue
■ Ford Trucks: Black/Pink
■ Dodge Ram Trucks: Orange/Black or Black/Orange
NOTE! A 1-amp diode must be installed in line on the factory wire between the wait-to-start indicator and the ECM. (See the following diagram for details.)
H1/7 LIGHT GREEN (-) door lock output
This wire provides a negative output to lock the vehicle's doors. To interface this output with the vehicle's power
door lock system, see the Door Lock Wiring Guide section of this guide.
© 2000 Directed Electronics, Inc. Vista, CA
13
H1/8 LIGHT BLUE (-) door unlock output
This wire provides a negative output to unlock the vehicle's doors. To interface this output with the vehicle's
power door lock system, see the Door Lock Wiring Guide section of this guide.
relay satellite key switch interface wire
connection guide
The heavy gauge wires leading from the relay satellite are used to energize high current circuits in the vehicle.
It is crucial that these connections are made correctly so that they are capable of handling the current demands.
For this reason, scotch locks, T-taps and other such connectors should not be used.
RED (2) (+)12V input for relays
Remove the two 30 amp fuses prior to connecting these wires and do not replace them until the satellite has
been plugged into the control module. These wires are the source of current for all the circuits the relay satellite will energize. They must be connected to a high current source. Since the factory supplies (+) 12V to the key
switch that is used to operate the motor, it is recommended that these wires be connected there.
NOTE: If the factory supplies two separate (+) 12V feeds to the ignition switch, connect one RED
wire of the satellite to each feed at the switch.
PINK (+) ignition output
Connect this wire to the ignition wire in the vehicle. (See Finding the Wires You Need section of this guide.)
ORANGE (+) accessory output
Connect this wire to the accessory wire in the vehicle that powers the climate control system. (See Finding the
Wires You Need section of this guide.)
PURPLE (+) starter output
Connect this wire to the starter wire in the vehicle. (See Finding the Wires You Need section of this guide.)
PINK/WHITE (+) output to second ignition circuit
Connect this wire to the second ignition wire in the vehicle. (See Finding the Wires You Need section of this guide.)
NOTE: For vehicles that do not have a second ignition wire, this connection is not required.

remote start harness (H2) wire connection guide
H2/1 BLUE status/factory security rearm output
This output is programmable. If programmed for status output, the wire will supply a 200 mA ground output at
all times the remote start is operating. If programmed for factory security rearm, the wire will supply a 200 mA
ground pulse whenever the remote start times out or is shut down using the transmitter.
H2/2 BLUE/BLACK (-) optional third ignition output
This output provides 200mA as soon as the remote starter is activated. It is used to power a relay to energize a
third ignition or accessory wire as shown below. This output is capable of driving two relays if necessary.
H2/3 GRAY (-) hood pinswitch input
This wire MUST be connected to the hood pinswitch. This input will disable or shut down the remote start when
the hood is opened.
H2/4 BROWN (+) brake switch input
This wire MUST be connected to the vehicle's brake light wire. This is the wire that shows (+) 12V when the brake
pedal is depressed. The remote start will be disabled or shut down any time the brake pedal is depressed.
H2/5 VIOLET/WHITE tachometer input
This input provides the module with information about the engine's revolutions per minute (RPMs). It can be
connected to the negative side of the coil in vehicles with conventional coils. In multi-coil and high energy ignition systems locating a proper signal may be more difficult. (See Finding the Wires You Need section of this guide
for finding the tachometer wire.) Once connected, you must teach the system the tach signal. (See Tach Learning
section of this guide.)

H2/6 BLACK/WHITE neutral safety switch input
Connect this wire to the toggle (override) switch as shown in Figure A. Connect the other wire from the toggle switch
to the PARK/NEUTRAL switch in the vehicle. This wire will test with ground with the gear selector either in PARK or
NEUTRAL. This will prevent the vehicle from accidentally being started while in a drive gear. This input MUST rest at ground
in order for the remote start system to operate. Connected properly the vehicle will only start while in PARK or NEUTRAL.
In some vehicles, the PARK/NEUTRAL position switch activates a factory starter lock-out that will not allow the
starter to operate in a drive gear. In these vehicles, connect this wire to the toggle switch as shown in Figure B.
Connect the other wire from the toggle switch to chassis ground.
Figure A
Figure B
IMPORTANT! Always use the Vehicle Safety Check section of this guide to verify that the vehicle
cannot be started in ANY drive gear and that the override switch is functioning properly.
neutral safety switch interface
Some vehicles combine the column shift mechanism and the mechanical neutral safety switch into one mechanical part. In these vehicles, it is impossible to interface the remote start system before the neutral safety switch.
With this type of vehicle, if the vehicle is left in a drive gear and the remote start system is activated, the vehicle
will move and may cause damage to persons or property.
According to available information, vehicles known to be manufactured this way are most General Motors trucks,
sport utility vehicles and column shifting passenger vehicles. Available information also indicates that pre-1996
Dodge Dakota pickups with 2.5 liter motors are also manufactured this way.
GM vehicles that have the neutral safety switch built into the column shifter can usually be identified by a purple
starter wire. Typically, vehicles that use an outboard mechanical switch use a yellow wire from the ignition switch
to the mechanical switch and a purple wire from the mechanical switch to the starter itself. Remember, this is
only a rule of thumb and is not intended as a substitute for proper testing.
IMPORTANT! Please see vehicle Safety Check section of this guide for testing procedures.
16

Vehicles with the neutral safety switch built into the column shifter require that the shifter be placed in park in
order to remove the keys from the ignition. As a result, it is possible to use the key-in-ignition sense switch to
prevent remote starting if the keys are in the ignition. (See General Motors Trucks, SUVs and Column-Shifting
Passenger Cars and Pre-1996 Dodge Dakota Pickups with 2.5 Liter Motors diagrams in this section on how to accomplish this.) The first diagram applies to all General Motors vehicles as of the date of this guide’s publication. The
second diagram applies to all pre-1996 Dodge Dakota pickup trucks with 2.5 liter motors. This solution has one
side effect: If the customer inserts the key in the ignition with the driver's door open, the remote start system
will shut down. If this interface is used, it is important to inform the customer that the driver’s door must be
closed before inserting the key into the ignition when the remote start is active. This will allow the customer to
turn the key on and shut the remote start down by pressing the brake, without the key sense wire shutting down
the unit prematurely.
You must also connect the H2/4 BROWN (+) shut-down input to the yellow wire on the relay satellite
ribbon cable. This prevents the remote start system from activating if the key is left in the “run” position. You
must use diodes to isolate the ignition circuit from the brake switch circuit as shown in the diagram below.
IMPORTANT! Once the interface is complete, attempt to remote start the vehicle with the door
closed and the key in the ignition. The vehicle should not start. If it does, re-check the
connections.
As of the date of this guide’s publication, the following list describes the types of vehicles that are known to
have a mechanical neutral safety switch instead of an electrical neutral safety circuit. The model years will vary
from vehicle to vehicle. This list will be updated periodically as new information is available; installers are
encouraged to call DEI® Technical Support at 1-800-753-0800 with updated information.

bypassing GM vehicle anti-theft systems (VATS)
Vehicles with the GM VATS (Pass Key) systems have a resistor embedded in the ignition key. If the VATS decoder
module does not measure the proper resistance when the vehicle is started, the starter and fuel pump may be
disabled for up to ten minutes. The system includes a "VATS pack" of resistors. One will match the resistor in the key.
The VATS wires will be two very light-gauge wires coming out of the steering column. The colors of the wires vary,
but they are often contained in orange tubing. Determine the value of the resistor in the key. Then follow the
diagram below to bypass VATS during remote start operation. If the BLUE status output has been programmed for
factory security re-arm, use the BLUE/BLACK Ignition 2 output to control the relay.
NOTE: When connecting to the VATS wires, it is not important which wire is cut.

1995 and newer vehicle anti-theft systems
(immobilizers)
1995 and newer vehicle anti-theft systems (immobilizers) require a bypass module. The bypass module allows for
easy interfacing, while still maintaining the OEM system’s integrity.
passlock I and passlock II (PL-1 and PL-2)
The Passlock I and Passlock II systems can be found in the following General Motors vehicles:
■ ‘95 and newer Cavalier and Sunfire
■ ‘96 and newer Achieva, Grand Am, and Skylark
■ ‘97 and newer Intrigue, Malibu, and Cutlass
■ ‘98 and newer trucks, vans, SUVs

■ 2000 and newer Impala and Saturn
Passlock I and II systems are VATS-evolved. Passlock systems still rely on the R-code to start, but the pellet is no
longer placed in the key. The resistor can now be found in the key switch. This allows for a greater number of
possible R-codes. In addition, Passlock systems require “seeing” the correct R-code at the correct time. To bypass
Passlock I and II, p/n 555L or p/n 555T is required.
passkey III (PK-3), transponder-based systems
The Passkey III system can be found in the following vehicles:
■ ‘97 and newer Park Avenue
■ ‘98 and newer Cadillac
■ ‘99 and newer U vans, Transport, Montana, and Silhouette
■ 2000 and newer Grand Prix, LeSabre, Monte Carlo, Lumina, Bonneville
■ 2001 and newer Aurora, Aztek and Rendezvous
Other transponder-based systems include: Acura, BMW, Dodge/Chrysler/Jeep, Ford, Honda, Infinity, Mazda,
Mercedes, Mitsubishi, Nissan, Toyota, Volkswagon, and Volvo.
PK-3 and the transponder-based systems use a transponder system that locks out the ignition and fuel system.
This transponder system is comprised of two parts. The first part, the transceiver, circles the key switch and is
activated when the key is placed in the key switch or turned to the run position. Upon activation, the transceiver
20

will excite the transponder, which is located (but not visible) in the head of the ignition key. The key transponder will then send a unique code back to the transceiver for evaluation. If the code matches a valid code of the
system, the vehicle will be allowed to start. Most of these transponder-based systems can be bypassed using p/n
555U. Some may require additional parts from the vehicle manufacturer. Consult you dealer for the applications.
For most Ford PATS transponders, as well as Lexus and Toyotas, p/n 555F can be used, except for the following
vehicles, which will require p/n 555U: ‘97 and newer Mark VII, and 2000 and newer Taurus/Sable,
Contour/Mystique and Focus.
optional anti-grind relay
This unit has anti-grind relay that will prevent the starter from engaging if the ignition key is accidentally turned
to the start position during remote start operation. If the BLUE status output has been programmed for factory
security re-arm, use the BLUE/BLACK optional third ignition output to control the relay.

door lock wiring guide
The light blue (H1/8) and light green (H1/7) lock wires provide 200mA negative pulses that are used to control
electric door locks. Most common interfaces are described in this section.
type A: (+) 12V pulses from the switch to the factory relays
The correct wires can usually be found in either kick panel. If you cannot get to the switch, and you find a set
of wires that pulse (+)12V alternately on lock and unlock, you must take care to ensure that it is not a Type C
direct-wire system.
Here is a test: Cut the wire which pulses (+)12V on lock, and then operate the switch to unlock.
■ If all doors unlock, the vehicle uses Type A system.
■ If you lose all door lock operation in both directions, you are operating the master switch in a Type C system.
■ If you lose all door lock operation of one or more doors, but not all motors stop operating, and other doors
still work, you have cut a wire leading directly to one or more motors. You must instead find the actual wires
leading to the switch.
Many domestically-made GM vehicles use Type A locks, while almost all domestically-built Fords are Type C (Ford
builds almost no Type A systems). Chrysler builds both Type A and Type C, so use caution.
WARNING! Many more GM locks are Type C than in previous years. The full-size pickups (1989-up),
many of the S10 Blazers, the Corvette, 1995 Cavalier/Sunfire 1993 - and newer, and Camaro/Firebird
all use Type C door locks, and cannot be controlled without a 451M!
To interface two relays, a 451M, or a 453T will be required.
22
© 2000 Directed Electronics, Inc. Vista, CA
type B: (-) pulses from the switch to the factory relays
This system is common in many Toyotas, Nissans, Hondas, and Saturns, as well as Ford models with keyless entry
systems (some other Fords also use Type B).
The switch will have three wires on it, and one wire will test ground all the time. One wire will pulse (-) when
the switch locks the doors, and the other wire will pulse (-) when the switch unlocks the doors. This type of
system is difficult to mistake for any other type.
© 2000 Directed Electronics, Inc. Vista, CA
23
type C: reversing polarity
Interfacing with a reversing polarity system requires either two relays or one 451M (not included).
It is critical to identify the proper wires and locate the master switch to interface properly. Locate wires that
show voltage on lock and unlock. Cut one of the suspect wires and check operation of the locks from both
switches. If one switch loses operation in both directions and the other switch operates in one direction only,
you have located one of the target wires. The switch that lost all operation is the master switch. If one switch
works both directions and the other switch works only one direction, you have a Type A system. If both switches
still operate, but one or more doors have stopped responding entirely, you have cut a motor lead. Reconnect it
and continue to test for another wire. Once both wires have been located and the master switch identified, cut
both wires and interface as shown below.
IMPORTANT! If these are not connected properly, you will send (+)12 volts directly to (-) ground,
possibly damaging the alarm or the factory switch.
24
© 2000 Directed Electronics, Inc. Vista, CA
type D: after-market actuators
In order for this system to control one or more aftermarket actuators, a 451M or two relays (optional) are needed.
Vehicles without factory power door locks require the installation of one actuator per door. This requires mounting the door lock actuator inside the door. Other vehicles may only require one actuator installed in the driver's
door if all door locks are operated when the driver's lock is used. This type of installation is required to operate
factory lock systems in Volvo (except 850), SAAB, and most Mazda, Isuzu and Subaru models.
The fuse used on 12-volt inputs should be 7.5A per motor installed in the vehicle.
IMPORTANT! Do not connect the outputs of the alarm directly to the actuator!

25
type E: mercedes-benz and audi (1985 & newer)
Type E door locks are controlled by an electrically activated vacuum pump; however, this DEI system is not
capable of controlling Type E locks.
type F: one-wire system
This system usually requires a negative pulse to unlock, and cutting the wire to lock the door. In some vehicles,
these are reversed. This system is found in late-model Nissan Sentras, some Nissan 240SX, and Nissan 300ZX 1992
and later. It is also found in some Mazda MPV and some Mitsubishi models.
One relay (optional) is used to interface to this type of system as follows:
26
© 2000 Directed Electronics, Inc. Vista, CA
type G: positive (+) multiplex
This system is most commonly found in Ford, Mazda, Chrysler and GM vehicles. The door lock switch or door key
cylinder may contain either one or two resistors. When interfacing with this type of door lock system, two relays
or a DEI 451M must be used.
single-resistor type
If one resistor is used in the door lock switch/key cylinder, the wire will pulse (+)12V in one direction and less
than (+)12V when operated in the opposite direction.
two-resistor type
If two resistors are used in the factory door lock switch/key cylinder, the switch/key cylinder will read less than
(+)12V in both directions.
determining the proper resistor values
To determine the resistor values, the door lock switch/key cylinder must be isolated from the factory door lock
system. For all testing, use a calibrated digital multimeter that is set to ohms.
1. Cut the output wire from the door lock switch/key cylinder in half.
2. Test with the meter from the switch side of the cut door lock switch/key cylinder wire to a reliable constant
(+)12V source. Some good constant (+)12V references are the power input source to the door lock switch/key
cylinder, the ignition switch power wire, or the (+) terminal of the battery.
3. Operate the door lock switch/key cylinder in both directions to determine the resistor values. If the multimeter displays zero resistance in one direction, no resistor is needed for that direction.
4. Once the resistor value(s) is determined, refer to the wiring diagram for proper wiring.
© 2000 Directed Electronics, Inc. Vista, CA
27
type H: negative (-) multiplex
The system is most commonly found in Ford, Mazda, Chrysler and GM vehicles. The door lock switch or door key
cylinder may contain either one or two resistors.
single-resistor type
If one resistor is used in the door lock switch/key cylinder, the wire will pulse ground in one direction and resistance to ground when operated in the opposite direction.
two-resistor type
If two resistors are used in the factory door lock switch/key cylinder, the door lock switch/key cylinder will read
resistance to ground in both directions.
determining the proper resistor values
To determine the resistor values, the door lock switch/key cylinder must be isolated from the factory door lock
system. For all testing, use a calibrated digital multimeter that is set to ohms.
1. Cut the output wire from the door lock switch/key cylinder in half.
2. Test with the meter from the switch side of the cut door lock switch/key cylinder wire to a reliable ground
source. Some good ground references are the ground input source to the door lock switch/key cylinder or the
battery ground.
3. Operate the door lock switch/key cylinder in both directions to determine the resistor values. If the multimeter displays zero resistance in one direction, no resistor is needed for that direction.
4. Once the resistor value(s) is determined, refer to the wiring diagram for proper wiring.

internal programming jumper
NOTE: The control module door must be removed to access the jumper.
digital tach threshold on/off
In most cases, this jumper can be left in the OFF position. Some new vehicles use less than 12 volts in their ignition systems. The unit may have trouble learning the tach signal in these vehicles. Changing the jumper to the
ON setting changes the trigger threshold of the digital tach circuit so it will work properly with these vehicles.
The vehicles affected include many newer Dodge/Chrysler/Plymouth vehicles, such as the Neon, Cirrus, Stratus,
Breeze and LH-based vehicles.

operating settings learn routine
The System Features Learn Routine dictates how the unit operates. The programmable operating settings of this
unit can be changed whenever necessary through the computer-based Learn Routine. The Program push-button
switch, plugged into the blue port, is used together with a programmed transmitter to change the settings. It is
possible to access and change any of the feature settings using the Program switch. To program settings, remember: Key, Choose, Transmit and Release.
To program the learn routine:
1.
Key. Turn the ignition on and then back off.
2.
Choose. Within 10 seconds, press and release the Program switch the number of times corresponding to the feature number you want to program. (See Features Menu section.)
Once the Program switch has been pressed and released the desired number of times, press it once more and HOLD
it. After a second, the LED will flash to indicate which feature you have accessed. For example, groups of eight
flashes would indicate access to the status output feature (Feature 8).
3.
Transmit. The transmitter is used to select the desired setting. As shipped, the unit is configured to the LED ON settings. These are called the default settings. Pressing Channel One
(usually Button I) will set it to the LED ON setting. The LED will light solid (stop flashing)
to indicate the setting. Pressing Channel 2 (usually Button II) will change the setting to
the LED OFF setting. The LED will go out indicating the change.
4.
Release. The Program switch can now be released.
You can advance from feature to feature by pressing and releasing the Program switch the number of times necessary to get from the feature you just programmed to the feature you wish to access. For example, if you just
programmed the run time (Feature 3) and you next want to program parking lights (Feature 4) to constant, release
the Program switch. Press and release it once to advance from Feature 3 to Feature 4. Then press it once more
and HOLD it. The LED will flash in groups of 4 to confirm that you have accessed Feature 4.
The learn routine will be exited if any of the following occurs:
■ The ignition is turned on.
■ The Program switch is pressed too many times.
■ More than 25 seconds elapses between programming steps.

feature descriptions
1 ENGINE CHECK ON/OFF: In the default setting the remote start will monitor either the vehicle's tach wire or
voltage depending on the programming of Feature 2. If programmed off, the vehicle will crank for the programmed crank time (Feature 5) and will not verify with tach or voltage that the vehicle is running. In the off
setting, if the vehicle fails to start, the ignition can stay on for the entire run duration. Using tach or voltage
check is always recommended if possible.
2 TACH WIRE SENSE/VOLTAGE SENSE: If the tachometer signal wire is used, this feature must be left in the
default (tach wire connected) setting. If programmed to the voltage sense setting, the unit will crank the starter
for a preset time that can be programmed in Feature 5. Once the starter has been engaged, the system will check
the voltage level to verify the engine is running. The threshold for the voltage level test can be programmed in
Feature 6. When using voltage sense mode, connection of the H2/5 VIOLET/ WHITE tachometer input is not necessary.

33
3 RUN TIME 12/24/60 MINUTES: This feature controls how long the engine will run before it “times out” and
shuts down. Programmed to the default setting the engine will run for 12 minutes. If the 24 or 60 minute run
time is desired, change this feature to the two or three flash setting.
4 PARKING LIGHTS FLASHING/CONSTANT: In the default setting, the unit will flash the vehicle’s parking lights
while remote started. The constant setting will turn the parking lights on solidly for the entire run duration.
5 CRANK TIME 0.6/0.8/1.0/1.2/1.4/1.6/1.8/2.0/4.0: If Feature 2 is programmed to the voltage sense setting,
the crank time must be set to the appropriate duration. The default setting is 0.6 second. If a different crank
time is desired, select Feature 5 and (while pressing the Program switch) press the Channel Two button to advance
through the LED Off settings. The unit will flash the LED to indicate which time is selected. Once the 4.0 second
setting is reached the next press of the Channel Two button will reset the system to the shortest setting.
6 VOLTAGE CHECK LEVEL HIGH/LOW: This feature only functions when Feature 2 is programmed to voltage sense.
Some vehicles have many accessories, which are turned on when remote started. In these vehicles, the variation
of voltage between the engine off and the vehicle running is very slight and the remote start unit may “think”
the vehicle has not started. This can cause the remote start to shut down after the vehicle has been started. If
this is the case, program this feature to the LOW position.
7 AUXILIARY OUTPUT: Factory alarm disarm/special accessory output: In the default setting this wire sends a
negative pulse that may be used to disarm the vehicle’s factory security system. If programmed for a special
accessory output, the wire can be used to energize a relay to power up extra accessory wires in the vehicle. The
special accessory output acts like many extra accessory wires. This output will energize when the remote start is
activated, stop while the starter is cranking, and then come back on when the vehicle has started successfully.
This allows more current to be available to the starter when needed.
8 BLUE WIRE STATUS OUTPUT/FACTORY RE-ARM OUTPUT: The blue (H2/1) wire will supply a 200mA (-) output
for the entire remote start run time. If programmed for factory re-arm output, this wire will supply a momentary
(-) 200mA pulse whenever the remote start times out or is shut down with the transmitter. This can be used to
re-arm many factory security systems.
9 ACTIVATION PULSES 1,2, OR 3: Determines how many pulses are needed on the WHITE/BLUE activation input
before the unit will activate or deactivate. This will not affect activation with the remote transmitter.
10 IGNITION-CONTROLLED LOCKING ON/OFF: When turned on, the doors will lock 3 seconds after ignition is turned on.
11 IGNITION-CONTROLLED UNLOCKING ON/OFF: When turned on, the doors will unlock when ignition is turned off.

timer mode
This unit can be programmed to start and run the engine every three hours. The engine will run for the programmed run time and then shut down. After three hours, the unit will restart the engine. A maximum of six
cycles can occur.
IMPORTANT! Timer Mode should be used only in open areas. Never start and run the vehicle in an
enclosed space such as a garage or carport.
The same procedure may be used to enter or exit Timer Mode using the remote transmitter:
1. Remote start the vehicle.
2. Press and release the transmitter button(s) controlling Channel Two.
3. Press and release the transmitter button(s) controlling remote start operation.
When entering Timer Mode, the engine should shut down. The parking lights (if connected) will flash four times
and the engine will restart. The system is in Timer Mode. The engine may be allowed to run for its programmed
run time, or the transmitter can be used to shut down the engine. Either way, the remote start system will restart
the engine again in three hours. Timer Mode is exited automatically after the sixth run cycle.
Timer Mode can also be exited manually as follows:
1. Make sure the remote start system is not operating the engine.
2. Turn the ignition on.
Timer Mode will be exited and the parking lights will flash four times.

safety check
Before vehicle reassembly, the remote system must be checked to ensure safe and trouble-free operation. The following test procedure must be used to verify proper installation and operation of the system. The installation
must be completed before testing, including connection to the brake switch and hood switch.
1. Test the BRAKE shutdown circuit: With the vehicle in Park (P), activate the remote start system. Once the
engine is running, press the brake pedal. The engine should shut down immediately. If the engine continues
to run, check the brake circuit connection.
2. Test the HOOD PIN shutdown circuit: With the vehicle in Park (P), open the hood. Activate the remote start
system. The vehicle should not start. If the starter engages, check your hood pin and connections.
NOTE: If programmed for Diesel Mode, the system will turn on the ignition, but the starter should
not engage with the hood open.
3. Test the NEUTRAL SAFETY shutdown circuit:
IMPORTANT! Make sure there is adequate clearance to the front and rear of the vehicle before
attempting this test.
a. Make sure the hood is closed and no other shutdown circuits are active.
b. Set the emergency brake.
c. Turn the ignition key to the run position but do not start the engine.
d. Put the vehicle in Drive (D).
e. Put your foot over the brake pedal but do not press down on it. Be ready to step on the brake to shutdown the remote start system.
f.
Activate the remote start system.
■ If the starter engages, immediately step on the brake to shut down the system. If it does engage,
recheck the neutral safety input connection. The vehicle may use a mechanical neutral safety switch.
(See H2/6 BLACK/WHITE neutral safety switch input in Remote Start Harness Wire Connection Guide
section of this guide.)
■ If the starter does not engage, the test is complete.
Once the system passes all three tests, the vehicle can be re-assembled and delivered. Do not the use the remote
start system or finalize the installation if it fails any of the safety check tests.

troubleshooting
■ The ignition comes on, but the starter will not crank.
Does it start with the key in the ignition? If so, does the vehicle have a VATS Pass-Key system?
Will it start with the brake pedal depressed? (Make sure to disconnect the brake shutdown when performing this
test.) If so, it may have a brake/starter interlock.
Is the correct starter wire being energized? Check by energizing it yourself with a fused test lead.
■ The starter cranks for six seconds but does not start.
Either the wrong ignition wire is being energized, the system’s ignition and accessory wires have been connected
backwards, or the vehicle has two ignition circuits. Try activating the unit with the ignition key in the “run”
position. If the vehicle then runs normally, retest your ignition system.
■ The starter continues to crank even though the engine has started.
Has the tach wire been learned? See the Tach Learning section of this guide.
Is the tach wire receiving the correct information? Either the wrong tach wire has been used, or a bad connection exists.
■ The climate control system does not work while the unit is operating the vehicle.
Either the wrong accessory wire is being energized or more than one ignition or accessory wire must be energized in order to operate the climate control system.
■ The remote start will not activate.
1. Check harnesses and connections. Make sure the harnesses are fully plugged into the remote start module.
Make sure there are good connections to the vehicle wiring.
2. Check voltage and fuses. Use a meter and check for voltage between the red wire in the 5 pin ribbon harness
and the black ground wire. If you have less than battery voltage, check the 3A and both 30A fuses on the
relay satellite. Also make sure that the ground wire is going to a chassis ground and not to something under
the dash.
3. Check diagnostics. The diagnostics will tell you which shutdown is active or not connected.
■ The remote start will activate but the starter never engages.
1. Check for voltage on the purple starter wire two seconds after the remote start becomes active. If there is
voltage present, skip to Step 4. If there is not voltage present, advance to Step 2.
2. Check the 30A fuses.
3. Check diagnostics. If the GRAY/BLACK wire is detecting ground upon activation, the starter will not crank.
4. Make sure the purple starter wire is connected on the starter side of the optional starter kill relay.
38

5. Does the vehicle have an immobilizer? Some immobilizer systems will not allow the vehicle to crank if active.
6. Check connections. The two red heavy gauge input wires on the relay satellite should have solid connections.
"T-taps", or "scotch locks" are not recommended for any high current heavy gauge wiring. Also, if the vehicle
has more than one 12-volt input wire, then connect one red wire to each.
■ The vehicle starts, but immediately dies.
1. Does the vehicle have an immobilizer? The vehicle’s immobilizer will cut the fuel and/or spark during unauthorized starting attempts.
2. Is the remote start programmed for voltage sense? If so, the start time may not be set high enough, or you
may have to adjust the voltage threshold in programming. Voltage sense will not work on some vehicles.
3. Check diagnostics. Sometimes a shutdown will become active during cranking or just after cranking.
■ The vehicle starts, but the starter keeps running.
1. Is the system programmed for engine checking off or voltage sense? When programmed for either of these
features, the engine cranks for the preprogrammed crank time regardless of how long it takes to start the
vehicle to actually start. Adjust to a lower cranking time.
2. Was the Tach Learn successful? The LED must light solidly and brightly to indicate a successful learn.
3. Make sure that there is a tach signal right at the purple/white tach input wire of the remote start. If not,
recheck the connection to the vehicle’s tach wire and make sure the wire is not broken or shorted to ground
leading to the remote start.
■ The vehicle will start and run only for about 10 seconds.
1. Is the remote start programmed for voltage sense? Try programming the unit for low voltage reference. If this
does not work, a tach wire should be used.
2. Check diagnostics.
■ Diesel vehicle does not wait to start.
1. Is the GRAY/BLACK wire connected to the wait-to-start wire of the vehicle?
2. Check the polarity of the wait-to-start wire. (See the Finding the Wait-to-Start Bulb Wire For Diesels section
of this guide.)
3. If wiring a negative wait-to-start bulb, make sure that a diode has been placed in line on the factory wire
between the vehicle’s ECM and the wait-to-start bulb. (See wiring description for the H1/6 GRAY/BLACK (-)
Diesel Wait-To-Start Bulb Input of the Primary Harness Wire Connection Guide.)
