on the switch and test the unlock wire. The correct wire will test (-) negative and the GREEN light
will glow bright. Release the unlock button and this wire should again glow both GREEN and RED (dimly).
Your vehicle has a “Type B” door locking system. Make sure to mark which wire is lock and unlock.Make
sure to mark which wire is lock and unlock.
“Type C” Door Lock Test (Most Fords, some Chryslers, GM Trucks)
Once you have located the lock and unlock wires in the vehicle using the wire color chart in this manual
or from our website, you will need to perform the same test as for the Type A system. Once you have
completed this test, and it tests the same as a Type A (as it should) you will need to cut the lock
wire in two. Now try the door lock switch in both the lock and unlock positions. The door locks should
not function, this is a Type C system. Proceed to Connecting Door Locks.
NOTE: If for any reason the doors unlock but do not lock with this wire, cut in two, this is a Type A
system.
NOTE: Once you have made the connections for the 5-pin door lock harness, you will need to plug the
door lock harness into the main module 5-pin plug on the front of the unit.

NOTE: When testing the door pin wire, make sure the dome
light is on. Some vehicles, if the door is left open
for a period of time, the dome light will go out,
resulting in a false reading.
DOME LIGHT
To determine if your dome light is turned on with (+)
positive or (-) negative trigger, probe for a wire in the
driver’s side kick panel that switches polarity when the
door is closed, then opened. You can also find this wire
going to the under dash courtesy lights.
•If this wire tests (+) positive, the RED light glows bright
when the door is open (as with most Fords) and when the
door is closed, this wire tests as a (-) negative, the
GREEN light glows bright, this is (+) positive dome light.
•If this wire tests (-) negative, the GREEN light glows
bright, when the door is open and when the door is closed,
this wire tests as a (+) positive, the RED light glows
bright, this is a (-) negative dome light.
If your dome light is a (-) negative (as most others are),
connect the VIOLET wire to the dome light wire from the
16-pin harness.
If you dome light is (+) positive (most Fords) you must
add Part #775 to use this option. See diagram below.
Once you have determined that your door locks are Type C
system, you must cut the unlock wire in two. Now you need
to determine which wire is coming from the switch and the
motor sides of each lock and unlock wire. First, test the
lock wires, press and hold the door lock switch in the
lock position. Test both lock wires, the wire that shows
(+) positive, and the RED light glows bright, will be the
switch side and the other wire will be the motor side of
this circuit. Mark these wires. Repeat these steps for the
unlock wire by pressing and holding the door lock switch
in the unlock position. The wire that shows (+) positive,
and the RED light glows bright, will be the switch side
and the other wire will be the motor side of the unlock
circuit.
Optional part #775 required.
