TESTING: Door Locks
There are three basic types:
“Type A” Door Lock Test (Most GMs and some Chryslers)
Probe both of your door lock wires going to the door lock switch usually located in the driver’s kick
panel. Probe the lock and the unlock wires, the test probe will show a (-) negative and the GREEN
light will glow bright on both the lock and the unlock wires. Press and hold the lock button on the
switch and test the lock wire. The correct wire will test (+) positive and the RED light will glow
bright. Release the lock button and this wire should show a (-) negative and the GREEN light will glow
bright. Now press and hold the unlock button on the switch and test the unlock wire. The correct wire
will test (+) positive and the RED light will glow bright. Release the unlock button and this wire
should show a (-) negative and the GREEN light will glow bright. Your vehicle has a “Type A” door locking
system. Make sure to mark which wire is lock and unlock. Connecting Door Locks. NOTE: “Type A” and
“Type C” locks will test the same. Make sure you run both tests before making your connections.
“Type B” Door Lock Test (Most Imports, some newer Fords)
Probe both of your door lock wires going to the door lock switch usually located in the driver’s kick
panel. Probe the lock and the unlock wires, the test probe will glow both GREEN and RED (dimly) on
both the lock and the unlock wires. Press and hold the lock button on the switch and test the lock
wire. The correct wire will test (-) negative and the GREEN light will glow bright. Release the lock
button and this wire should again glow both GREEN and RED (dimly). Now press and hold the unlock button
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.

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.
