Type G: Positive (+) multiplex resistor-based circuit.
Type H: Negative (-) multiplex resistor-based circuit.
at the switch
Three-wire switches will have either a constant ground input or a constant
(+)12V input, along with the pulsed lock and unlock outputs to the factory relays.
Some vehicles have no external switch. The switches are inside the actuator, and
instead of pulsing, the proper wires will flip-flop from (+)12V to (-) ground as the
door locks are operated.
Direct-wired switches will have a (+)12V constant input and one or two (-)
ground inputs, along with two output leads going directly to the lock motors.
type A: positive-triggered, relay-driven system
I I M M P P O O R R T T A A N N T T ! ! The H2/1 and H2/6 wires are not required for wiring the door locks.
For detailed wiring instructions for these two wires, refer to the beginning of the Door
Lock Harness (H2) Wire Connection Guide section. Depending on the type of door
lock system, there may be additional H2 harness wires that are not used for wiring the
door locks.
