Door lock wire diagrams

Important! Depending on the vehicle, the door locks may be controlled by an
optional data bus expansion module. If so, no door lock interface wiring is
required.
There are eight different types of door lock systems (Type A - H). Refer to the
vehicle-specific wiring instructions on the web and the chart below to help
determine which door lock system your vehicle uses.
Note: The more common type of door lock systems are Type A or Type B. Any oth-
er, Types C thru H, will require external relays or a Directed Electronics 451M.
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.
Type D: Adding one or more aftermarket actuators. These include central locking
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 and some newer
Hyundais.
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.
Note: You can use a 456L door lock learn module for Type G and H, instead of
relays and resistors.
