the type of locking system the vehicle has before connecting any wires. Incorrect connection
are several types of door
in vehicles today. Below is listed the many types of common locking systems:
): Many Imports; Late model Ford & General Motors
Negative trigger door lock systems send a Negative (Ground) pulse to existing factory relays to l
unlock the vehicle doors.
Positive Trigger (+): Many General Motors; Chrysler / Dodge / Plymouth
Positive trigger door lock systems send a Positive (+12V) pulse to existing factory relays to lock and unlock
Ford/Lincoln/Mercury/Dodge/Chrysler/Plymouth and early 90’s GM Trucks
The door lock/unlock motors are controlled directly from the lock and unlock switches in the door. The lock
and unlock wires rest at Negative Ground when not in use. When the lock or un
lock button is pressed, one of
the circuits is “Lifted” and replaced with +12V causing a lock or unlock to occur.
Single Wire (Dual Voltage): Late model Chrysler/Dodge/Plymouth Vehicles, some
Dual Voltage systems have lock/unlock switches that send varying levels of Positive voltage OR Negative
ground current to the SAME wire for both lock and unlock. When the vehicle’s Body Computer Module (BCM)
or door lock module senses
different voltages on this wire, the system will either lock or unlock. Single wire
door lock systems require relays and resistors.
