ABOUT YOUR DOOR LOCKING SYSTEM
All power door locking systems have switches to activate doors. These
switches are usually located on the door or center console. In some cases
(BMW) the switch is located inside the drivers door actuator. Your door
lock switch will have at least 2 trigger wires, one for locking your doors
called the LOCK wire, and one for unlocking your doors called the
UNLOCK wire. Your switch will also have one sender wire. When the
sender wire connects to a trigger wire your doors will activate (unlock or
lock).
When you push your door lock switch to "lock", your sender wire
connects with your lock wire, to lock your doors. When you push your
door lock switch to "unlock", your sender wire connects with your unlock
wire, to unlock your doors.
Negative and Positive triggers are the two main types of door locking
systems. On a negative trigger system your sender wire is "-". When you
give a "-" to the trigger wires they will activate your doors (unlock or
lock). On a positive trigger system your sender wire is "+". When you
give a "+" to the trigger wires they will activate your doors (unlock or
lock).
LOCATION OF WIRES
1. Open the Door
2. Locate the Power Door Lock Switch.
3. Remove the switch from the door so that you can gain access to the
wires

CODE LEARNING
a. Turn key to ON position, press valet button for 3 seconds. The parking
lights will flash once to indicate code learning mode. Press any button in
order to learn the desired remote. The parking lights and LED will flash
once for confirmation, after each remote transmitter is learned. Up to 4
remote transmitters can be learned at this time.
b. Turn key to OFF position or wait for 5 seconds and system will exit
code learning.
REMOTE DOOR LOCKING
a. Press button 1. The parking lights will flash once. The starter/ignition
kill circuit will be enabled and the lock output will pulse for 1 second or
until button 1 is released.
b. LED will begin flashing slowly.
REMOTE DOOR UNLOCKING
a. Press button 2. The parking lights will flash twice. The starter/ignition
kill circuit will be disabled and the unlock output will pulse for 1 second
or until button 2 is released.
b. LED will be off.
CH1 OUTPUT
Press button 1 to output channel 1 continuously until button 1 is released.
CH2 OUTPUT
Press button 2 to output channel 2 continuously until button 2 is released.
Note: If your car has no door lock switch then you have central locking
(BMW). Central locking systems have the unlock, lock, and sender wires
built in to the drivers side door actuator (inside door). There is no need to
remove the driver's door panel since these wires travel from the driver's
door, through the door jam, to the interior of your vehicle. Test all wires
coming from the drivers door for the lock, unlock, and sender wires.
Wire according to the proper system.

ACTUATOR
This system has a switch instead of an actuator in the drivers door. You
will need to mount an actuator (GT series) in the drivers door to control
your locks. Wiring diagram comes with actuator (GT series)
1. Install the fuse on the red wire then connect the BROWN/BLUE, and
RED wires to a constant 12 volts.
2. From the keyless entry unit connect the ORANGE/BLUE,
ORANGE/GREEN, and BLACK wires to metal ground.
3. Mount the actuator, and connect the BLUE/WHITE and
GREEN/WHITE wires to the actuators green and blue wires.
Testing (w/an airbag safe digital volt-ohm meter)
Connect the testlight wire to a ground (-), then probe all wires from your
door lock switch to determine the lock, unlock, and sender wires.
1. If you come to a wire that LOCKS your doors when probed (-), then
you have found the lock wire. Connect the BLUE/WHITE wire from the
keyless entry unit to this wire.
2. If you come to a wire that UNLOCKS your doors when probed (-),
then you have found the unlock wire. Connect the GREEN/WHITE wire
from the keyless entry unit to this wire.
3. From the keyless entry unit connect the BROWN/BLUE wire to your
sender wire. This wire will be a constant "-".
4. Install the fuse on the red wire then connect the RED wire to a
constant 12 volts (+), and the BLACK wire to a body ground.
Testing (w/an airbag safe digital volt-ohm meter)
Connect the testlight wire to a 12 volts (+), then probe all wires from
your door lock switch to determine the lock, unlock, and sender wires.
1. If you come to a wire that LOCKS your doors when probed (+), then
you have found the lock wire. Connect the BLUE/WHITE wire from the
keyless entry unit to this wire.
2. If you come to a wire that UNLOCKS your doors when probed (+),
then you have found the unlock wire. Connect the GREEN/WHITE wire
from the keyless entry unit to this wire.
3. From the keyless entry unit connect the BROWN/BLUE wire to your
sender wire. This wire will be a constant "+".
4. Install the fuse on the red wire then connect the RED wire to a constant
12 volts (+), and the BLACK wire to a body ground.
