type H: negative (-) multiplex

The door lock switch or door key cylinder may contain either one or two resistors. When

interfacing with this type of door lock system, two relays or a 451M must be used.

Single-Resistor Type

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.

Two-Resistor Type

If two resistors are used in the factory door lock switch/key cylinder, the door lock

switch/key cylinder will read resistance to ground in both directions.
