power wire, or the (+) terminal of the battery.
3. Operate the door lock switch/key cylinder in both directions to
determine the resistor values. If the multimeter displays zero resis-
tance in one direction, no resistor is needed for that direction.
4. Once the resistor value(s) is determined, refer to the wiring dia-
gram for proper wiring.
type H: negative (-) multiplex
The system is most commonly found in Ford, Mazda, Chrysler
and GM vehicles. The door lock switch or door key cylinder
may contain either one or two resistors.
SSIIN NG GL LE E--R RE ESSIISST TO OR R T TY YP PE E:: If one resistor is used in the door lock
switch/key cylinder, the wire will pulse ground in one direction and
resistance to ground when operated in the opposite direction.
