This security system can control two common power door lock types without any additional parts! With
certain vehicles, or if an actuator is to be installed, either a 4 4 5 5 1 1 M M Door Lock Relay Satellite or two relays will
be required.

This security system can control Type A door locks directly, with no additional parts. The switch will have three
wires on it, and one will test (+)12V constantly. The others will alternately pulse (+)12V when the switch is
pressed to the lock or unlock position.
If you cannot get to the switch, and you find a set of wires that pulse (+)12V alternately on lock and unlock,
you must take care to ensure that it is not a Type C direct-wire system.
I I M M P P O O R R T T A A N N T T ! ! If you mistake a Type C direct-wired system for a Type A positive-pulse system, the
module will be damaged!

■ If all doors unlock, the vehicle uses a Type A system.
■ If you lose all door lock operation in both directions, you are operating the master switch in a Type C system.
■ If one or more, but not all, motors stop operating, you have cut a wire leading directly to one or more motors.
