NTT!! The door lock outputs are low current and should not be attached direct-
ly to any high-current device; they are only to be used to activate relays
type A: positive (+) 12-volt pulse
The system can control Type A door locks directly, with no additional parts. The switch
will have three wires on it; one will test (+)12 volt constantly. The others will alternate-
ly pulse (+)12 volt 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 (+)12 volt alter-
nately on lock and unlock, make sure that it is not a Type C direct-wire system.
Here is a test:
Cut the wire that pulses (+)12 volt on lock, and then operate the switch to unlock.
■
If all doors unlock, the vehicle uses type A system.
■
If you lose all door lock operation in both directions, you are operating the mas-
ter switch in a Type C system.
■
If you lose all door lock operation of one or more, but not all motors, and other
doors still work, you have cut a wire leading directly to one or more motors. You
must instead find the actual wires leading to the switch.
