REC-11+ Installation Paginated
Resetting The Programmable
Features
The installer may quickly and easily return all 17 programmable features back to the factory
settings. Changing individual features were explained in detail in the previous section. However, a
Total System Reset feature allows the installer, if needed, to quickly return all 17 features to the factoryset default positions. If only returning the Override Code to the factory default is desired, this is also
easily accomplished. To perform Override Code Reset or Total System Reset, follow these steps:
Step 1- Locate the small round hole in the lower control module case. Two solder dots are visible
on the PCB beneath this hole.
Step 2 - Short the two solder dots together, and hold them shorted (a slotted jeweler's screwdriver
works well for this).
REC-11+
REMOTE RECEIVER UNIT
Step 3 - Momentarily shorting the solder dots together will result in one chirp. The Secret Override
Code is now returned to the factory-set default of 1 & 0 presses.
Step 4 - Shorting the solder dots for a few more seconds will result in two more chirps. When this
occurs all 17 Programmable Features are now returned to the factory-set default positions.
See the Owner’s Guide for transmitter programming instructions
(transmitters are pre-programmed into the REC-11+).

The Programmable Features
Installation Considerations
The REC-11+ Remote Keyless Entry has 17 programmable features that can be used to customize
the system’s operation. Brief programming instructions and a list of these features follows; see the
Owner’s Guide booklet for complete details of the features and their programming.
To program features:
The REC-11+’s Main Control Module contains electronic components, so always mount this
module at a secure location within the vehicle's interior compartment. Ensure that moisture, vibration
and temperature extremes are minimized. Acceptable locations may include mounting behind the
dash, behind the glovebox or other interior panels.
Step 1 - Turn off the ignition, and within 5 seconds press the Valet Switch 5 times.
The system will respond by sounding the piezo or horn for a short period.
The system's Wiring Connections should be securely connected to the appropriate vehicle
wires with the proper terminals, connectors, or by soldering and insulating with quality vinyl electrical tape or heat shrink tubing. All wiring should be carefully routed to avoid the possibility of
chaffing or otherwise being damaged. Make all required connections, then plug the harnesses into
the control module.
Step 2 - Enter the Secret Override Code- if this is the default setting, press the Valet Switch once.
The system will respond one long, then two short chirps.
Repeats Steps 3 and 4 for each remaining feature to be programmed. If 10 seconds of no
programming activity expires (not pressing the LOCK or UNLOCK or selecting another feature) the
system will automatically exit the programming mode, as indicated by sounding a long chirp.
The installer has two basic installation options for the Status Light and Valet Switch. These
items may be separately installed as a Custom Mounting into or on existing interior panels; or, by
utilizing an included Combination Holder assembly.
Custom Mounting:
Select a suitable surface in the vehicle interior to mount the Status Light
where it can be easily seen by the operator, and preferably where it can be seen from the exterior of
the vehicle. Drill a 9 / 32” hole in a suitable interior panel, route the wiring harness through the hole
to the control module, and snap the Status Light in place. Plug the Status Light’s small 2-pin plug into
the matching red port on the control module. Mount the Valet Switch, using its adhesive pad, in a
hidden location which is accessible to the operator; carefully route the wires to the control module, and
plug the valet switch’s blue 2-pin plug into the control module’s blue 2-pin port.
Page 22
Page 3
Step 3 - Within 10 seconds access the desired feature by pressing the Valet Switch the same number
of times as the feature number.
The system will acknowledge the entry by chirping the same number of times.
Step 4 - Within 10 seconds, press the transmitter’s LOCK button to turn features on, or press the
UNLOCK button to turn features off (see list on the next page).
The system will acknowledge turning the feature "on" by chirping once, or "off" by chirping twice.
To complete any of the mounting methods, carefully route the wirings to the control module to
avoid any chances of them being chafed or pinched, and plug them into to their respective control
module ports.

Combination Holder Mounting:
The included Combination Holder assembly for the Status
Light and Valet Switch is shown in the exploded view at right.
Mount the combination holder assembly in a location where it can
easily be seen by the driver, and preferably where it can be seen
from outside. Two mounting options are provided: double-sided
adhesive tape for “no-mar” mounting, and 2 Phillips screws for a
more permanent mounting.
If using the adhesive tape, properly prepare the mounting
surfaces to ensure good adhesion, and then affix the completed
combination holder assembly. To complete the holder assembly,
adhere the Valet Switch to the upper combination holder half,
insert the Status Light into the upper half collar, and then snap the
two halves together with the wires exiting the hole in the rear of
the upper half.
If using the screws for a more permanent mounting, carefully
screw the upper half to its mounting location (avoid overtightening),
install the Valet Switch and Status Light to the upper half, and then
snap the assembly halves together with the wires exiting the hole
in the rear of the upper half.

BLACK WIRE: (-) Chassis Ground- This wire supplies chassis ground for the unit's operation.
Connect the Black wire to the metal frame of the vehicle, preferably using an existing machine-threaded
fastener and the proper size ring terminal. Make sure that the Black wire's ring terminal has contact
with bright, clean metal. If necessary, scrape any paint, rust or grease away from the connection point
until the metal is bright and clean. The thin Black wire attached to the units with a built-in receiver
is the antenna wire. Do not connect this wire to anything or your transmitter's range will be
reduced or eliminated. Stretch this wire out and as high as possible for the best operating range.
RED WIRE: (+) 12 Volt Constant Power- This wire supplies constant (+) 12 volts for the unit's
operation. This wire must have (+) 12 volts at all times. The recommended connection for the Red
wire is to the constant (+) 12 volt wire at the ignition switch harness.
YELLOW WIRE: (+) Ignition Power- This wire supplies (+) 12 volts to the unit whenever the
ignition switch is turned "on". This connection should be made at the ignition switch harness, to the
primary ignition circuit. Primary ignition has 0 volts when the ignition key is in the "Lock", "Off" and
"Accessory" positions; and 12 volts in the "Run" and "Start" positions.
GRAY WIRE: (-) Optional Output- This wire will have a 1 second Negative (-) output whenever
the transmitter's button II is held pressed for 3 seconds. Use a relay for trunk release and other options,
or, in many cases this wire may be connected directly to the activation circuit of other devices, such
as a Remote Starter unit.
Page 5
ORANGE WIRE (-) Starter Interrupt Output- The Orange wire is an output for an optional starter
disable socket and relay. The starter interrupt prevents the vehicle from starting only if the transmitter
has been used to lock the doors, or if any automatic starter interrupt options have been programmed
to operate.
The optional DLS -3 And 2 Or 3 SPDT Relays is the most universal doorlock interface
available. The DLS-3 with 2 relays can lock and unlock all doors (most doorlock system types); when
used with 3 relays the “Driver Door Unlock Priority” may be configured. Diagrams are shown for
all three of the common vehicle doorlocking systems (the driver's door motor unlock wire will always
be 5 wire reversal system, regardless of the system type).

Older Mercedes Benz and other European vehicles have Pneumatic Doorlocks which will
require the optional DLS-V and 2 SPDT Relays. This system consists of electrical switches (built into
pneumatic actuators) which supply 12 volts or ground to a pneumatic pump, which in turn operates all
of the actuators. The switches in the actuators are operated when the doors are locked or unlocked by
the inside doorlock knob or the key in the exterior doorlock cylinders. The polarity supplied by the
switch determines if the pump sends vacuum or pressure through hoses to the actuator. Since the pump
must operate for about 3 seconds, the REC-11+’s
programmable feature #8 must be changed from the
.8 second default setting to the optional 3 second
setting. The target wire in the vehicle will change
polarity from Negative to Positive as the doors are

be in either kick panel or at the supply pump

itself, which is located in the trunk or under

To interrupt the vehicle's starter circuit, the starter wire must be located and cut. This connection
should be done as close to the ignition switch as possible. Use a voltmeter, not a test light, to find the
correct wire, which is the wire from the ignition switch to the starter solenoid. CAUTION! Avoid the
airbag circuit! Improper use of a test light can cause deployment of the airbag, which may result in
bodily injury! Test lights can also damage on-board computers and associated sensors. The starter
wire will read Positive 12 Volts only when ignition key is in "start" position (cranking the engine). Cut
this wire at a suitable location. Confirm that this is the correct wire by turning the ignition switch to
the "start" position. The starter should not engage. Connect the optional starter disable socket's Red
wire to the ignition switch side, and its White wire to the starter solenoid side. Be sure that good, solid
electrical connections are made as this generally is a high amperage circuit. Connect the module's
Orange wire to the Orange wire of the starter disable socket.

White Wire: Positive Flashing Light Output- This is a Positive 12 Volt output for exterior
flashing light confirmation and to attract attention to the vehicle if the optional Anti-Carjacking feature is utilized and activated. Also, upon unlocking, this circuit will flash twice then stay on for 30
seconds to confirm unlocking and to illuminate the way to the vehicle. This feature gives added
security when approaching the vehicle at night.
Connect this wire to the vehicle's Positive 12 Volt parking light circuit. This wire can usually be
found at the following locations: at the headlight switch, at the fuse/junction block, or in the rear body
harness in the driver kick panel. Some vehicles, notably Toyotas, have a parking light relay which is

The second situation is a vehicle which lacks power doorlocks; adding an actuator to each door
allows remote locking and unlocking via the REC-11+. Or, an alternative is the addition of a complete
power doorlocking kit instead, which provides in-vehicle power control of the doorlocks, in addition
to remote operation by the REC-11+.

2 SPDT relays. The important thing to remember is that the wires in this system rest at ground, which
means that the wires must be "opened", or cut, to make the connections.
Examine the wires on the back of the switch; normally 5 wires will be found. Of the wires, one will
be constant Positive 12 Volt, regardless of the switch's position. Two wires will be grounded regardless
of the switch's position. Of the two remaining wires, one will show Positive 12 Volt when the switch
is pushed to "lock", and the other will show Positive 12 Volt when the switch is pushed to "unlock".
When the correct wires are found, they must be cut. Notice in the diagram that the driver's switch is the
primary switch and referred to as the "switch" wires. The wires that go to the secondary switch are
referred to as the "motor" wires. Even though the cut is made between the switches, the two sides are
still correctly called the "switch" and the "motor" sides.
There are two situations in which the installer must Add an Optional “DS” Actuator, DLS,
and 2 Relays. The first of these situations is a vehicle having a “partial” power doorlock system. In
this type of system, mechanically locking and unlocking the driver's door will operate an electrical
switch in that door which supplies voltage to actuators in the other doors. There is no actuator in the
driver's door, only a switch. An indication of this type of power doorlock system is when the driver
door key will operate the passenger door, but the passenger side will not operate the driver door.
The only way to remotely operate all of the doors is add a single actuator to the driver’s door, which
thus operates all of the doors.

triggered by a Negative Ground circuit from the headlight switch. These cars can still be connected
directly to the White wire by finding the parking light circuit after the relay, usually at the Fuse/Junction
Block. The correct wire will show Positive 12 Volts when the headlight switch is in the "Parking Light"
and "Head Light" positions. 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. Do not attempt to flash the parking lights by connecting the
White wire to a rheostated (dimmer) circuit! This will backfeed the parking lights through the rheostat
or illumination control module, and possibly cause damage to the vehicle or REC-11+ control unit.
Also, if the White wire touches chassis ground, the Printed

Otherwise, another option would be to use the REC-11+’s

Pair of White/Black Wires: Domelight Supervision- The two White/Black wires are for

supervision, connect the non-fused White/Black wires to the vehicle's domelight wire. The fused

Audible Output Options
The Remote Piezo Speaker Port offers several options for adding audible operation to the
REC-11+. These include chirp confirmation of received transmissions, indications when programming feature or transmitters, the addition the safety feature of remote panic, and optional AntiCarjacking features. The included piezo speaker, or buzzer, may be plugged in temporarily, such as
for programming, or it can be permanent (example: tie-wrap it out of sight behind the lower dash).
The best utilization of this output is cut off the piezo and use an additional SPDT relay to connect
the REC-11+ to the vehicles’ horn, as shown in this diagram :

Connecting The Power Doorlocks
The REC-11+ has a plug-in doorlock output port; this 4 pin port produces a negative pulse for
locking the doors (inside pin), a constant 12 volt pin for the optional relay coils only (second pin from
the inside), a first negative pulse for driver door or all door unlock (second pin from the outside), and
a second negative pulse for optionally unlocking all other doors (outside pin). The doorlock interface
needed will depend upon the type of power doorlocks the vehicle has. The vehicle must have existing
power doorlocks. A vehicle that does not have power doorlocks may be equipped for remote keyless
entry operation by adding an Omega electric doorlock actuator to each of the doors and an optional DLS
or DLS-3 and relays (this will allow the REC-11+ only to operate the doorlocks).
The vast majority of power doorlocks are found as three system types: 3 wire negative pulse, 3 wire
positive pulse and 5 wire reversal, rest at ground. Other power doorlock systems which may be
encountered are the vacuum pump types found in most Mercedes vehicles and the single wire, dualvoltage which has appeared in some late model vehicles. The best way to identify a doorlock system
is to examine the doorlock switch's wiring. The following sections describe the types of doorlock
systems found and the available optional interfaces.

3 Wire Negative Doorlocks using the Control Unit Outputs
A 3 Wire Negative Pulse system is indicated by the presence of three wires at the switch. Of
these, one will show constant ground, regardless of whether the switch is being operated or not (at rest).
Of the remaining two wires, one will show ground when the switch is pushed to the "lock" position,
and the other wire will show ground when the switch is pushed to the "unlock" position. With the switch
at rest, these two wires will read voltage, usually 12 volt positive but in some cases less. The wires from
the switches operate doorlock relays or a doorlock control unit with built-in relays. The correct
connection point is between the switches and the relays or control unit.
The 3 Wire Positive Pulse system is very similar to the 3 Wire Negative Pulse system except
the vehicle's doorlock switches use Positive 12 Volt pulses to operate the vehicle's doorlock relays.
Examine the wires on the back of the switch. Of the three wires, one will be constant Positive 12 Volt,
regardless of the switch's position. Of the two remaining wires, one will show Positive 12 Volt when
the switch is pushed to "lock", and the other will show Positive 12 Volt when the switch is pushed to
"unlock". Since the keyless entry system's output polarity must be reversed from negative ground to
12 volts positive, an optional doorlock interface must be used. Three interfaces are available - the
models DLP-P3, the DLS and the DLS-3 with optional SPDT relays. The DLP-P3 and DLS diagrams
are shown on the following page, and the DLS-3 is described in detail on page 19-21.
