most common is the negative triggered door lock system. If your
vehicle has a negative triggered door lock system, follow the steps
below. If your vehicle has any other type of door lock system
then, the easiest way to determine which type of door lock
system you are working with is to remove the master locking

center console. Once you have determined which type of factory
door lock circuit you are working with, and the color codes of
the switch wires to be used, you can usually simplify the instal-
lation by locating the same wires in the vehicle’s kick panel. If no
central locking switch is found, the installation may require a
door lock actuator.
There are eight common types of door lock circuits (some vehi-
cles use more unusual systems):

they function the same way as the wires on the switch.
