There are eight common types of door lock circuits (some vehicles use more unusual systems):
■
TTyyp pee A A:: Three-wire (+) pulse controlling factory lock relays. Most GM, some Ford and Chrysler, 1995 Saturn,
some new VW, newer BMW.
■
TTyyp pee B B:: Three-wire (-) pulse controlling factory lock relays. Most Asian vehicles, early Saturn, some BMW and
Porsche.
■
TTyyp pee CC:: Direct-wired reversing-polarity switches. The switches are wired directly to the motors. This type of
system has no factory relays. Most Fords, many GM two-doors cars and trucks, many Chryslers.
■
TTyyp pee D D:: Adding one or more aftermarket actuators. These include slave systems without an actuator in the
driver’s door, but with factory actuators in all the other doors. Type D also includes cars without power locks,
which will have actuators added. All Saabs before 1994, all Volvo except 850i, all Subaru, most Isuzu, and
many Mazdas. Some mid-eighties Nissans, pre-1985 Mercedes-Benz and Audi.
■
TTyyp pee EE:: Electrically-activated vacuum systems. The vehicle must have a vacuum actuator in each door. Make
sure that locking the doors from the driver's or passenger side using the key activates all the actuators in
the vehicle. This requires a slight modification to the door lock harness. Mercedes-Benz and Audi 1985 and
newer.
■
TTyyp pee FF:: One-wire system - cut to lock, ground to unlock. This system is found in late-model Nissan Sentras,
some Nissan 240SX, and Nissan 300ZX 1992 and later. It is also found in older Mitsubishis, and some early
Mazda MPV’s.
■
TTyyp pee G G:: Positive (+) multiplex. This system is most commonly found in Ford, Mazda, Chrysler and GM vehi-
cles. The door lock switch or door key cylinder may contain either one or two resistors.
■
TTyyp pee H H:: Negative (-) multiplex. The system is most commonly found in Ford, Mazda, Chrysler and GM vehi-
cles. The door lock switch or door key cylinder may contain either one or two resistors.
■
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.
■
Many BMW’s and VW’s 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.
