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.

There are eight common types of door lock circuits (some vehi- cles use more unusual systems):

■Type A: Three-wire (+) pulse controlling factory lock relays. Most GM, some Ford and Chrysler, 1995 Saturn, some new VW, newer BMW.

■Type B: Three-wire (-) pulse controlling factory lock relays. Most Asian vehicles, early Saturn, some BMW and Porsche.

■Type C: Direct-wired reversing-polarity switches. The switch- es are wired directly to the motors. This type of system has no factory relays. Most Fords, many GM two-door cars and trucks, many Chryslers.

■Type 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 pre-1997 Subarus, most Isuzus, and many Mazdas. Some mid-eighties Nissans, pre-1985 Mercedes-Benz and Audi.

■Type E: Electrically-activated vacuum systems. The vehicle
