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
