INTRODUCTION
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
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.
