There are eight different types of door lock systems (Type A - H). Refer to the vehicle-specific wiring instruc-
tions on the web and the chart below to help determine which door lock system your vehicle uses. On
some late model GM vehicles a door lock data interface module may be required.
Type A: Three-wire (+) pulse controlling factory lock relays.
Type B: Three-wire (-) pulse controlling factory lock relays.
Type C: Direct-wired reversing-polarity switches. The switches are wired directly to the motors. This type of
system has no factory relays. Relays (not included) will be required for this type of door lock system.
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 E: Electrically-activated vacuum systems.
Type F: One-wire system - cut to lock, ground to unlock.
This is a very rare system found mainly in early 90's imports.
Type G: Positive (+) multiplex. One wire controls lock and unlock using resistor(s).
Type H: Negative (-) multiplex. Same as type G system, but uses (-) pulse instead.
All other door lock systems will require additional relays and/or resistors. A Directed Electronics 451M
Doorlock module can be used for these other applications. The 451M also includes diagrams and resistors
required for most applications.
