*VIOLET and VIOLET/BLACK wires are common at the fuse holder.
H2/G BLACK/WHITE input to on-board interior light illumination relay #87
This wire determines what the output polarity of H1/9 will be. If the door pin circuit is negative, connect to
chassis ground. If the door circuit is positive, connect to a fused 12V source.
IMPORTANT! The H2/G wire is not required for wiring the door locks. Depending on the type of door
lock system, there may be additional wires in the Door Lock Harness (H2) that are not required
used in wiring the door locks.
H2/A - H2/F power door lock wires
The system has door lock relays on-board, and can directly interface with most electric power door lock systems
drawing 20 amps or less. These can also drive aftermarket actuators directly. (Some vehicles require that an after-
market actuator be added to the driver's door to allow system control, see Type D wiring section).
identifying the door lock system
The easiest way to determine which type of door lock system you are working with is to remove the master
locking switch itself, which is usually on the driver's door or on the 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 installation 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.
NOTE: Always retest the wires in the kick panel to be sure they function the same way as the wires
on the switch.
