the wires show partial ground through the relay’s coils.
2) The doorlock switch in a Reversing system will have 5 wires, while a Positive
pulse system the switch will have 3 wires.
3) A Positive pulse system uses factory relays or a control unit, a Reversing system does
not.
5 Wire Reversing Polarity Systems
This power doorlock system differs from the negative and positive pulse systems in that there
is no doorlock control unit or relays. In this type of system, the switches themselves supply the
positive voltage directly to the doorlock actuators, and, more importantly, provide the return
ground path. It is important to note that the lock and unlock wires in this system actually rest
at chassis ground. This means that both the lock and unlock wires must be "opened", or cut,
to make the proper connections.
Examine the wires on the back of the switch. (Normally 5 wires will be found
1) One wire will show +12 Volts, regardless of the switch's position.
2) Two wires will be grounded regardless of the switch's position.
3) One wire will show +12 Volts only when the switch is pushed to "Lock".
4) One wire will show +12 Volts only when the switch is pushed to "Unlock".
- When the lock /unlock wires are found, they must be cut one at a time. If the correct wires
are cut the door locking system should not operate from the primary switch.
- Notice that in the diagram the driver's switch is the primary or “Master” switch (in some
vehicles, the primary switch is on the passenger's side). The half of the cut wires which come
from this primary switch are referred to as the "Switch" side. The half of the cut wires which
go to the secondary switch are referred to as the "Motor" side even though the cut is made
between the switches.
Introduction & Safety Considerations
Congratulations for choosing your Remote Starter and Keyless Entry system. The unit
offers the convenience of locking and unlocking your vehicle’s doors with the press of a
button, and starting your vehicle's engine from the comfort of your home or office, allowing
it to warm up in winter and cool down in summer. The unit can also be configured to
remotely open your vehicle’s trunk.
It is highly recommended that this system be professionally installed, as the sophistication of the modern automobile and the complexity of this type of product installation is often
beyond the abilities of most do-it-yourselfers.
There are several important safety considerations with using and installing the keyless entry and remote starter. Among them are:
3 This unit is for vehicles with an automatic transmission only. Installation in a
vehicle equipped with a manual transmission can result in property damage or
personal injury.
3 This unit is for fuel injected gasoline or diesel engines.
3 Children should not be left unattended in, or be allowed to play with the activating transmitters of any remote starter equipped vehicle.
3 Do not use the remote starter feature in an enclosed garage or other structure.
This unit is a very flexible system. It has capabilities, such as sounding the horn, which
may or may not be utilized in your installation. It also has many programmable features
which can affect its operation. While these are explained as thoroughly as possible in this
guide, your Omega dealer or installer is the best source for information about your system.

Warning: The Positive pulse system can be confused with the 5-wire Reversing Polarity system. This
is because both systems show +12 Volt pulses on the “Lock” and “Unlock” wires when the vehicle’s
switch is pressed respectively. It is critical to identify which system is present, since if +12 Volts is pulsed
into a Reversing Polarity system, which rests at ground, a direct short circuit will occur.
3 main differences between a Positive pulse and a Reversing Polarity system:
1) In a Reversing system the Lock/Unlock wires rest at ground, while in a Positive system
operate the vehicle’s on-board doorlocking relays. If the vehicle’s Negative pulse
doorlocking system requires more than 500mA Negative output, optional relays must
be used.

22 Gauge Blue Wire:
500mA ( - ) Unlock Output
Connection If Desired. The Blue wire supplies a negative pulse for locking the
vehicle's doors. Programmable feature #12 changes the single unlock pulse to be a double
unlock pulse.
This harness, which plugs into the White 3-pin port on the control module, is the power
doorlock outputs by which the unit operates the vehicle’s power doorlock system (the
vehicle must have existing power doorlocks). The doorlock interface needed to allow the
system to operate the doorlocks will depend upon the type of power doorlocking system
the vehicle is equipped with. The following sections describe typical power doorlocking
systems, which are categorized as “3 Wire Negative Pulse”; “3 Wire Positive Pulse”, and “5
Wire Reversing Polarity” systems.
3 Wire Negative Pulse Systems
This power doorlock system is simplest of all doorlocking systems. A Negative pulse system
will have only three wires at the doorlock switch.
Examine the wires on the back of the doorlock switch:
1) One wire will show Ground, regardless of the switch's position.
2) One wire will show Ground only when the switch is pushed to "Lock".
3) One wire will show Ground only when the switch is pushed to "Unlock".
The lock & unlock wires coming out of the switch operate the vehicle’s doorlock relays or a
control unit with on-board relays, therefore the lock & unlock wires will read Positive voltage,
up to +12 Volts, when the switch is at rest. The correct connection point is between the
switches and the relays. The Red connector's Green and Blue wires can be connected
directly to the vehicle’s Negative pulse system since only a Negative pulse is required to
20-Gauge Gray Wire:
( - ) Trunk Release Output
Connection If Desired. The Gray wire has a 500mA Negative output which is
operated by the transmitter button with the “open trunk” icon, and this output is designed
for trunk release. In most cases, an optional external relay will be needed.
( - ) Horn Output
20-Gauge Brown Wire:
Connection If Desired. The Brown wire is a 500mA Negative output designed to sound
the vehicle’s horn for audible operation confirmations and the remote “panic” feature. The
Brown wire may be connected directly to the vehicle's horn switch wire, provided that the
circuit operates with 1/2 Amp of current or less. The horn wire is typically found around

500mA ( - ) Lock Output
The Green wire supplies a negative pulse for locking the
starting to be operated, such as when you have your vehicle serviced or leave it
with someone else. The Valet Switch, in the Receiver Unit, is used to engage Valet Mode:
• At any time simply press the Valet Switch for 5 seconds; the Status Light within the
Receiver Unit will light steady, to indicate Valet Mode, and stay illuminated continuously
while the system is in Valet Mode.
Once the unit is in Valet Mode, an attempt to remote start will instead be acknowledged by
1 long and 3 short parking light flashes, but no starting attempt. If the horn is connected,
it will sound briefly and then chirp 3 times.
• To turn off Valet Mode, simply press the Valet Switch until the Status Light turns off.
Valet Mode only prevents the remote starting operation; the lock, unlock, and trunk release
functions all continue to operate when the unit is in Valet Mode.
Remote Panic
To Activate Panic*: Press & Hold either transmitter LOCK or UNLOCK
button for 3 seconds
• The horn will sound*, the parking lights will flash and the doors will lock or unlock, depending on the transmitter button used. To deactivate Panic, simply again press either the
LOCK or UNLOCK button- Panic stops with either locked doors or unlocked doors, depending on which button is used.
* The horn will not sound if Panic is activated when the system is in Valet Mode. Connection of the
horn may require additional parts, and may not be included in a standard installation.
To Activate the Trunk Release*:
Press & Hold the lower right
transmitter TRUNK button for 2 seconds
• The trunk will be released after 2 seconds, and the Status Light will flash twice. If the
doors are also programmed to unlock with Trunk Release, the parking lights will flash twice
and stay on for 30 seconds, and the horn will chirp 2 times if it is connected.
* Connection of the trunk release may require additional parts, and may not be included in a standard
installation.
Multiple Vehicle Operation
The unit’s transmitter can operate two different vehicles equipped with this system. The
slide switch on the side of the transmitter is utilized for this- one car can be operated in
switch position “A” and the second car in switch position “B”.
Transmitters must be coded for multiple vehicle operation- an easy procedure which is
explained on pages 17-19.
Caution: When such a wire is located, be sure to also test that it is non-rheostated:
While metering the wire, operate the dash light dimmer control. The correct wire will
show no change in voltage when the dimmer is operated. Some vehicles have a parkinglight relay which is triggered by a Negative signal from the headlight switch. In these vehicles, the White wire must be connected after the relay, usually at the Fuse/Junction Block.
Do NOT connect the White wire directly
to the vehicle’s headlights. An external relay is

The Receiver Unit
The unit has a total of 14 “programmable features”; most of these are “operational”
features, some are “installation”-related, and one returns all features to the factory setting.
These features can be changed by very easily by placing the unit into a “Features Programming Mode” and selecting features with the Valet Switch, and then using the
transmitter’s buttons to set the feature as desired. The chart on the next page shows the
Programmable Features, and detailed step-by-step programming instructions follow the

wire can usually be located in the vehicle in either kick panel area, in the wiring
harness which is routed into the cab from the door. The Yellow/Green wire has a
-Ground pulse whenever the unit has an unlock output or its remote start operation is
activated.
20-Gauge Yellow/Red Wire:
( - ) OEM Arm Output
Connection If Needed. This output may be used to arm a factory-installed alarm, or, if
the vehicle is equipped with a Retained Accessory Power circuit, this output can be used to
“spike” the door pin switch wire, which will turn off the Retained Accessory Power circuit.
To arm a factory alarm after remote start engine run stops, connect the Yellow/Red wire
to the vehicle's factory arm wire. This wire will show Negative polarity when a key is held in
the "lock" position in the door key cylinder. This wire can usually be located in either kick
panel, in the wiring harness from the door, as it is routed between the door key cylinder and
the factory alarm.
To use this wire to turn off Retained Accessory Power, locate a vehicle wire within the
door or doorjamb which shows Negative when the door is open. Should such a wire be
found which is positive, a relay is needed to reverse the Yellow/Red wire’s Negative output
to Positive. The Yellow/Red wire produces a Negative pulse output whenever the system
turns off the engine after it has been remotely started.
20-Gauge Pink/Black Wire:
( - ) Start Activation Input
Connection If Needed. The Pink/Black wire allows for alternative devices such as an
existing keyless entry or alarm system to activate the remote start operation. If the Pink/
Black wire receives a Negative pulse, the unit will start the vehicle's engine, provided that
all safety circuits are in the proper status. After the engine has been started by remote
control, another Negative pulse on the Pink wire will turn the unit off, stopping
read 1 to 6 volts AC with the engine idling, and will increase with engine speed.
2) Switch the selector slide switch on the unit’s control module to the right toward the
12-pin secondary harness (see page 21 and the markings on the control module).
3) Adjust the tach signal by starting the engine and turning the right adjustment screw on
the control module slowly clockwise until the indicator LED lights solid.
4) Test the operation by remote starting and checking that the indicator LED slights solid.
The starter engagement is long enough for the engine to start, but without grinding. If
needed adjust the crank time by turning the adjustment screw clockwise for more signal
sensitivity and counterclockwise for less.
20-Gauge Green/Red Wire:
( +/- ) Glow Plug Input
Connection If Needed. The Green/Red wire allows the unit to be used with diesel
engines, operates only if programmed (feature #13) and is also polarity-programmable. Connect the Green/Red wire to the wire in the vehicle which powers the glow plugs, or the wire
which illuminates the “Wait To Start” light on the instrument panel. When connected, the
unit will not engage the starter if the Green/Red wire has +12 Volts; in other words, using
this wire simply delays the unit’s engagement of the starter. If the “Wait To Start” light in the
vehicle has a Negative switching circuit, change the position of the White “Glow Plug +/Select” Jumper on the control module to reverse the Green/Red wire’s polarity operation.
20-Gauge Yellow/Green Wire:
( - ) OEM Disarm Output
Connection If Needed. If needed, the Yellow/Green wire allows the MARS to disarm a
factory alarm system. Connect the Yellow/Green wire to the wire in the vehicle which is
connected to one of the doorlock key cylinders. The typical OEM alarm has an electrical
switch in the key cylinders which switches -Ground when the key unlocks the door. This
How to program the features:
1) Turn the ignition key “On”, then “Off”.
2) Within 7 seconds press the Valet Switch 5 times.
The Status Lights will flash twice, and if the horn is connected, it chirps twice.
The parking lights turn on, and stay on while in programming mode.
3) Select the feature to be changed by pressing the Valet Switch the same number of times
as the feature number (example: feature #3 = 3 presses).
The Status Lights will flash the same number as the Valet Switch presses just
entered. If the horn is connected, it also chirps the same number.
Count the number of flashes or chirps to confirm that the desired feature has been
chosen (if needed, reenter the Valet Switch presses).
4) Once the feature has been confirmed, press the transmitter buttons as follows:
“LOCK” = Feature’s Default 1st setting (1 Status Light flash & 1 horn chirp)
“UNLOCK” = Feature’s optional 2nd setting (2 Status Light flashes & 2 horn chirps)
• Most of the programmable features offer more than one optional choice:
“START” = Feature’s 3rd setting (3 Status Light flashes & 3 horn chirps)
“TRUNK” = Feature’s 4th setting (4 Status Light flashes & 4 horn chirps)
Once the Status Lights flash a response, and the horn chirps the response
(if connected), the feature is set.
• More features to program? Go to step 5.
• Only needed to program the one feature? Allow MARS to exit Programming Mode.
5) Select another feature by again making a new entry of Valet Switch presses
(repeating step 3) and again setting the newly chosen feature with the transmitter
(as in step 4).
Exiting Programming Mode:
Simply allow the unit to time out of Features Programming Mode by not performing
any programming actions for 15 seconds; or, turn the ignition “On” to exit immediately.
The unit indicates its exit from Features Programming Mode with 2 short and 1
long Status Lights flashes and the parking lights turning off. If the horn is connected it will have 2 short and 1 long chirps.
About the Programmable Features
The unit’s Programmable Features are arranged so that the “operational” features, which
are of user interest, come before the “installation”-related features. The purpose of installation-related features is to adapt the unit to certain vehicle situations; these are to utilized
at the time of the installation only.
• Features #1 through #10 have “daily use” benefits, and may be programmed by the user,
if so desired, to suite their preference or needs.
• Features #11 through #13 should not be programmed by the user!
• Feature #14, “Reset All Features To Default”, quickly and conveniently returns all features to their factory settings. This is extremely helpful if there has been a mistake in
programming, or if there is any doubt or confusion of the settings.
cess. Consider both methods before selecting one to use, and then connect the
Black/Yellow wire accordingly. Either connection method must be performed at
the completion of the installation, after all other wiring connections are made.
Smart Start sensing is more commonly used, for its ease of installation. The unit as
received has Smart Start selected. Smart Start “reads” the vehicle’s battery voltage level
via the Black/Yellow wire to determine engine running status. To use Smart Start:
1) Connect the Black/Yellow wire to constant “Battery” 12 volts. This may done at the
ignition switch harness, or at the battery itself for better sensitivity.
2) Switch the selector slide switch on the unit’s control module to the left toward the
module corner (see page 21 and the markings on the control module).
3) Adjust Smart Start by starting the engine and turning the left adjustment screw on the
control module slowly clockwise until the indicator LED starts flashing. Turn the adjustment until the LED is flashing in a consistent and regular manner.
4) Test the operation by remote starting and checking that the indicator LED shows the
same consistent flashing (good voltage signal learned), and that the starter engagement is long enough for the engine to start, but without grinding. Turn clockwise for
more crank time and counterclockwise for less crank time.
Tach Wire sensing is generally more reliable, and preferable in cases were the engine
normally starts inconsistently, or is hard to start . With this method the Black/Yellow wire
reads the engine speed (tach) information directly from a wire in the vehicle. To use the
Tach Wire method:
1) Connect the Black/Yellow wire to the vehicle's tach wire, which is found in the engine
compartment, although in many cases it may also be located inside the vehicle. To use
a multimeter to verify the correct tach wire, set it for AC Volts scale. The correct wire will
braces are not adequate, and the area must be clean, bright metal.
20-Gauge Red/Black Wire:
( + ) Brake Input
Connection Required- The Red/Black wire must be connected. It is part a critical
safety feature which disables the unit whenever the brake pedal is pressed. Connect the
Red/Black wire to the brake switch wire which shows +12 Volts when the brake pedal is
pressed. The brake switch is typically located above the brake pedal, and usually mounted
to the brake pedal support bracket. Make this connection securely for long-term reliability,
and thoroughly test the operation of this circuit.
20-Gauge Blue Wire:
( - ) Hood Input
Connection Required- The Hood Safety Switch must be installed and the Blue
wire must be connected. This prevents operation of the unit if the hood is open. Carefully
install the included pin switch so that it is open (pin down) when the hood is shut and closed
(pin up) when the hood is open. Connect the Blue wire to the pin switch and carefully route
this wire through the firewall, using an added or existing grommet, avoiding any hot or
moving parts. If there is an existing hood pin switch for an alarm system, you may use it for
this purpose, but the two systems must be diode-isolated. Instead of using a pin switch to
monitor the hood's open or shut status, an Omega AU-46 Mercury Tilt Switch may used.
Connect one of the AU-46's wires to Negative Chassis Ground and connect the remaining
wire to the Blue wire.
20-Gauge Black/Yellow Wire:
Engine Detect Input
Connection If Desired. The Black/Yellow wire is the engine detect wire. The unit utilizes two different methods of monitoring the vehicle during the remote starting pro-
Explanations of the User’s “daily use” Programmable Features:
• Feature #1, “Coded Override”, may be used another programmable feature, “Ignition
Activated Anti-Carjacking”. See “Feature #7”.
• Feature #2 is “Engine Running Time”. When the unit remotely starts the engine, the run
time before automatic shut-off is adjustable. A 10 minute run time is the factory setting,
with options of 20, 30 or 40 minutes. When programming (see page 12) press “UNLOCK”
for 20 minutes; press “START” for 30 minutes; press “TRUNK” for 40 minutes; or press
“LOCK” for 10 minute setting.
• Feature #3, “Doors Lock/Unlock Upon Ignition On/Off”, has the unit automatically lock
the doors when the ignition key is turned on, and unlock them when the key is turned off.
• Feature #4, “Horn Confirmation With Doorlocking”, offers several forms of audible confirmation when the doors are remotely locked and unlocked. Audible confirmations in any
form require the connection of the unit to the vehicle’s horn, or to an optional electronic
siren. Confirmation with remote doorlocking has the horn chirp once after locking, and
twice after unlocking. Two volume levels are selectable and an “On Demand” operation
whereby the first press of the “LOCK” or “UNLOCK” button is silent, and a second press
will produce the confirmation chirp or chirps.
When programming (see page 12) press “UNLOCK” for the On Demand operation;
press “START” to turn off the confirmation chirps; press “TRUNK” for the Quiet chirp; or
press “LOCK” for louder chirp (the factory “Medium” setting).
• Feature #5, “Horn Confirmation With Starting”, is similar to the previous feature, and
again, the horn output must be connected. When the unit remote starts the
engine it will chirp the horn 3 times; this feature allows the choice of 3 chirp volume
levels (instead of two- “On Demand” chirps can’t be used as the “START” button operation toggles between “start” and “stop”), or completely turning off the starting chirps.
The factory chirp setting is “Medium”; when programming (see page 12) press “UN
LOCK” to turn the starting chirps off; press “START” for the loud chirps; or press “TRUNK”
for the quiet starting chirps. Press “LOCK” for the factory setting “Medium” starting chirps.
• Feature #6 is not used on the unit.
Anti-Carjacking Feature and Coded Override:
• Feature #7, “Ignition Activated Anti-Carjacking” is described here in full detail.
The unit features Anti-Carjacking protection which only requires programming it to
operate, and connection of the horn output. Adding an optional starter interrupt circuit to
the Anti-Carjacking further enhances recovering the vehicle should it still be taken.
When it is utilized, Anti-Carjacking automatically starts operating every time the ignition
key is turned “On”. When the key is turned on, the user has 53 seconds in which the
Valet Switch must be pressed 1 time to cancel the full engagement of Anti-Carjacking. At
53 seconds, the horn will start a chirping pattern as reminder, and the Valet Switch can
still be pressed. At 60 seconds after the key was turned “On”, Anti-Carjacking fully engages, sounding the horn and flashing the parking lights; pressing the Valet Switch will
no longer cancel the feature. Instead, the ignition key must be turned “Off”, then back
“On”, and then within 5 seconds the Valet Switch must pressed; a few seconds later AntiCarjacking will turn off.
• Once the full Anti-Carjacking occurs, the horn output ceases if the ignition key is turned
“Off”, but resumes whenever it is “On”.

Wiring Connections - 12 Wire Harness
18-Gauge Black Wire:
System Ground
Connection Required. Connect the Black wire to a very good, clean chassis ground.
A recommended connection is to an existing machine-thread bolt, either in the driver's kick
panel, steering column area or a major structural member behind the dash. Small dash
Jumper
Accessory
Starter
Programming the Yellow/Green Wire’s operation: Locate and open the small access panel
on the top of the control module case. Place the
Jumper as shown on the pins below the removable
panel on the control module. The factory setting is
the center “Ignition #2” position.
Ignition #2
Wiring - 3 Wire Connector / Satellite Relay Port
The Red satellite relay port can be used, if needed, to configure optional relays to energize
additional Ignition or Starter circuits, and Omega OEM security bypass interfaces also plug
into this port. Prewired dual relay sockets are available, and a plain 3-wire harness is
provided to use this port.
22 Gauge Green Wire:
500mA ( - ) Starter Output
Connection If Needed. This 22 gauge Green wire is a 500mA Negative output having
basically the same operation as the 12 gauge Green Starter output wire. If two or more
Starter wires are present in the vehicle an optional relay is needed, connected to satellite
port Green wire as shown in the diagram.
22 Gauge Red Wire:
( + ) Output For Optional Relay Coil
Connection If Needed. The Red wire supplies constant 12 Volts that can be used to
power the relay's coil only- DO NOT use this Red wire for the optional relay(s) power
input (pin 87).
Anti-Carjacking can be made even more difficult to defeat with the use of “Coded Override” (Feature #1). Instead of 1 Valet Switch press to turn it off after fully engaging,
multiple presses must be made. The number of presses, 1 through 9, are chosen and
programmed by the user Even if a customized Coded Override is used, only one Valet
Switch press is needed to cancel Anti-Carjacking before it fully engages at 60 seconds; after
that point that the correct custom Coded Override must be entered to turn off Anti-Carjacking.
How to program Coded Override:
• Feature #1 allows the user to custom-program the “Coded Override”. Place the MARS
into Features Programming Mode (page 12) and access Feature #1. After the Status
Light flashes once and the horn chirps once to confirm that Feature #1 is ready for programming, press the transmitter “LOCK” button for each digit of the desired customized
Coded Override, but wait after each single “LOCK” button press for a single Status Light
flash and horn chirp before pressing the button again for the next digit. When all of the
digits have been entered in this fashion, wait for the Status Light and horn to flash and
chirp the complete total number.
Example: for a Coded Override of “3 presses”, programming would be: enter Features
Programming Mode, select “feature 1” (response is 1 flash / 1 chirp). Press “LOCK”, wait
for 1 flash / 1 chirp; press “LOCK” again, wait for 1 flash / 1 chirp; press “LOCK” again, wait
for 1 flash / 1 chirp. Now continue to wait, until the MARS has 3 flashes / 3 chirps. Exit
programming mode, and the Coded Override is now 3 presses of the Valet switch.
• Feature #8 is not used on the unit.
• Feature #9, “Unlock Doors With Trunk Release” has the doors unlock automatically when
ever the remote trunk release is used. If this feature is turned off (press “UNLOCK” in
programming, page 11), the trunk release will still operate when used, but the doors will
not unlock. When this feature is on, the unit flashes the parking lights twice,
and the horn chirps twice (if connected) when trunk release is used; if this feature
is turned off, the trunk release operates with 2 Status Light flashes only.
• Feature #10 is “Pulsed or Steady Horn / Siren Output”. This feature’s first function is to set
the units’ audible output for use with the vehicle’s existing horn, or with an optional
electronic siren. If the unit is connected to the vehicle’s horn, Feature #10’s second
function is providing three different horn pulse patterns when it sounds for the “panic”
feature. When programming (see page 11), the three horn pulse choices are: press
“TRUNK” for the slow horn pulses; “START” for medium pulses; or “LOCK” for default
medium horn pulse setting. To use an optional electronic siren, program steady output by
pressing “UNLOCK” when programming. Do not use the steady output setting for the
horn-continuous use will damage it.
Explanations of the “installation-related” Programmable Features:
Programmable Features #11 through #13 should only be used by the installer. All of these
features program certain aspects of the unit to match the vehicle into which it is installed.
Do not change any of these features once the unit is installed and properly configured.
• Feature #11 is “Starter Cranking Time”. This sets the base starter cranking time for the
Smart Start voltage sensing engine detection method (page 29). When using Smart
Start, a longer starter cranking time may be used for engines which do not start on the
first remote start attempt. Programming choices are: .5 second (“LOCK”, the default
setting); .75 second (“UNLOCK”); 1.25 second (“START”); and 1.5 second (“TRUNK”).
page 26-27).
Note: If a security system is present which utilizes a starter interrupt circuit, the
Green wire must be connected to the Starter Motor side of the interrupt.
12-Gauge Yellow Wire:
Ignition Output
Connection Required. Connect the Yellow wire to the vehicle's Ignition wire (also known
as “Primary Ignition”). This wire will show +12 Volts when the ignition key is in the "Run"
and "Start" positions and no voltage in the "Off" and "Accessory" positions. This wire is
found in the ignition switch wiring harness (see diagram on previous page).
Note: If two Primary Ignition wires are present, use the Yellow/Green wire for the second,
or configure an optional relay to the 3-pin Red port (see pages 26-27).
12-Gauge White Wire:
Accessory Output
Connection Required. Connect the White wire to the vehicle's Accessory wire. This
circuit supplies power to the Heat, Ventilation and Air Conditioning (HVAC) system. This
wire will show 12 Volts when the ignition key is in the "Run" and "Accessory" positions and
No voltage in the "Start" and "Off" positions. The connection point for this wire is also found
in the ignition switch wiring harness.
12-Gauge Yellow/Green Wire:
Programmable Output
Connection If Needed. The Yellow/Green wire is an additional output which can be
programmed to operate as an Ignition output, Accessory output or Starter output. As received, it is programmed as an Ignition #2 output. This wire may be used in cases where
the vehicle has more than one of any of these three circuits.
and affix the Receiver Module. Carefully route the module’s 5-wire ribbon cable to the
control module; plug the cable into the Black 3-pin port on the rear of the module, and
plug the remaining two connectors into their respective 2-pin ports.
Optional: Should it be desired, an optional separately-mountable Valet Switch and
Status Light are available. The Receiver Module must still be used for its receiver section,
but the Valet Switch and/or Status Light may be placed as desired.
Wiring Connections - 6 Wire Main Harness
(Two 12-Gauge) Red Wires:
Constant +12 Volts Input
Connection Required. Connect both Red wires to constant 12 Volts. The source used
must supply adequate amperage. The most common sources are the battery (+) terminal
or the ignition switch wiring harness. Good reliable connections and use of the included
fuses are a must. Note that some ignition switches have the electrical switch as part of the
mechanical switch; others have the electrical switch lower on the steering column and
connected to the mechanical switch by a linkage. The ignition switch wiring harness is the
best source for these wires, and the Starter, Ignition #1 and Accessory wiring connections.
12-Gauge Green Wire:
Starter Output
Connection Required. Connect the Green wire to the vehicle's Starter wire. This wire
will show +12 Volts only when the ignition key is in the "Start" position. This wire is also
found in the ignition switch wiring harness (see diagram on previous page). Some vehicles
have a second Starter wire known as a "Cold Start" wire. When this is encountered, two
options are available: program the Yellow/Green wire as a second starter output, or use an
optional relay configured to the 3-pin Red port to energize the second Starter wire (see
• Feature #12 is “Doorlock Output Options”. The default setting is the most
common, “Single” pulse for both Lock and Unlock (press “LOCK” when programming features). The first option changes the unlock output only to 2 pulses, which is
needed by certain vehicles (press “UNLOCK” to program). The second option configures
both lock and unlock outputs to have a 3 second duration, to operate vacuum pump
doorlocks (press “TRUNK” when programming). The third option changes the lock
output only to have a 28 second output pulse, which allows the unit to operate the total
closure feature in vehicles which are thus equipped (press “START” when programming
the feature). The longer output only operates from a transmitter signal, and not with
ignition-activated locking.
• Feature #13 is “Gasoline or Diesel Engine” When programming, press “LOCK” for the
“Gasoline” setting. Diesel engines have three options: pressing “UNLOCK” selects “Monitor
Glow Plug Wire”, by which the unit delays engaging the starter until its glow plug input
wire detects the glow plugs turning off; and two preset delay periods before starter engagement: 10 seconds (“START”) and 20 seconds (“TRUNK”).
Resetting all of the Programmable Features:
• Feature #14 returns all Programmable Features to their factory default settings. Enter
programming mode (page 12), select Feature #14, and press the transmitter’s “LOCK”
button. The unit will acknowledge the “LOCK” input with a single Status Light flash
and horn chirp (if connected), and then immediately exit programming mode with the
normal confirmation of 2 short and 1 long Status Light flashes and horn chirps.
Note: When a Programmable Features Reset is used, any feature which needs to be in
a setting different from the default setting will have to be reprogrammed.
Programming Transmitters
MARS can be operated by up to four transmitters. Replacement or additional
transmitters must be programmed to operate the unit. The multi-car operation capability
also requires that transmitters be programmed into the second vehicle (with the transmitter’s
multi-car switch in “B” position). Coding transmitters is a very easy process.
• Have present all of the transmitters which are to operate the unit. When one
transmitter is programmed, all prior transmitters are erased- program all transmitters.
• If the additional transmitters are for a second car, put the multi-car switch on these
transmitters only in the “B” position.
1) Turn the ignition key “On” (and leave it “on”).
2) Within 7 seconds press the Valet Switch 5 times.
The receiver unit’s Status Lights turn on, and the horn chirps once (if connected).
3) Within 15 seconds press the first transmitter’s “LOCK” and “UNLOCK” buttons together.
The unit will acknowledge the transmission by momentarily turning off the
Status Lights and chirping the horn 1 time.
4) Within 15 seconds press the next transmitter’s “LOCK” and “UNLOCK” together.
The Status Lights turn off and the horn chirps once.
Repeat this action for each remaining transmitter.
Exiting Programming Mode:
Simply allow the unit to time out of the programming mode, by not transmitting for 15
seconds; or, turn the ignition “Off” to exit immediately.
The MARS indicates its exit from programming mode by turning off the Status
mined which control module wires will be used. Most installers will list these wires,
then "map out" the installation by locating and noting the target wires in the vehicle.
This will also determine the best location for the control module, which is mounted upon
completion of the installation.
The remote starting unit duplicates the actions that occur within the ignition switch
when you use your key to start the engine. Because of this, most of the main wiring
harness connections will be made at the ignition switch harness. The ignition switch wires
usually are high amperage circuits, which means that high reliability connections must be
made- soldering of all connections is recommended.
Caution! Avoid the Airbag circuit! Especially avoid any harness or wires encased in Yellow or Red tubing or sleeves. Do not use a standard test light, as it can deploy an airbag or
damage on-board computers and sensors.
Main Module:
The Main Module should be mounted in a location close to the ignition switch (where
many of the wiring connections are made); typically, hidden behind the driver’s side
dash.
Receiver Module:
An essential part of the unit is the plug-in window mount Receiver Module, which also
contains the Valet Switch and Status Lights. The unit will not operate unless this Receiver
Module is plugged-in. Select a desired mounting location for the Receiver Module; optimum
performance is obtained by mounting this module high and unobstructed on the vehicle’s
glass, such as the windshield behind the rearview mirror. Make sure the glass surface is
clean and free of dust, grease, or debris. Peel the backing off of the adhesive tape
Installation Instructions
Lights and a series of horn chirps.
After reading this manual, start the installation by affixing the WARNING
DECAL to a visible area in the engine compartment!
Do not attempt to install this Remote Car Starter into a manual transmission
vehicle! Doing so could cause serious property damage, personal injury,
and will void all warranties!
Be aware of, and avoid, any airbag circuitry! Due to the fact that an installer
will not be in a normal, upright seated position, severe injury may occur in an
accidental airbag deployment!
The use of a Digital Multimeter (DMM) or Volt-Ohm Meter (VOM) instead of a
standard testlight is required. This can greatly reduce the risk of an accidental airbag deployment or on-board computer damage.
Battery gases are explosive! Avoid sparks and do not smoke while working
near the vehicle's battery!
Always protect wires routed through the firewall from sharp metal edges and
hot parts of the engine! Always fuse positive wires at their source!
Installation Considerations: This entire booklet should be read before starting the
installation. An understanding of which control module wires are to be used and their
functions is essential. Installations will vary from car to car, as some control module wires
are required, while others are optional. Before starting the installation, it should be deter-
Any time that transmitters are programmed to operate the unitt, for
48 hours afterward every time that the ignition key is turned “on”
the horn will briefly chirp and the Status Light will flash the number
of operating transmitters. This is “Unauthorized Transmitter Alert”,
protecting against unauthorized transmitters.
