Hopefully someone will be able to help me out here. I'm installing the Clifford Millenia in a 95 BMW 325i and need guidance on wire connection from alarm module to door lock/unlock leads. The car has a pre-wired alarm connector behind the glove box with most of the needed inputs for plug and play. There is a door lock and unlock wire where I need to tap into however the Clifford has the following:
RED / Orange - Door unlock (normally open)
RED / Green Door lock (normally open)
WHITE/ Orange Door unlock (common)
WHITE/ Green Door lock (common)
Gray/Green Door lock (normally closed) - not used*
Gray/Orange ( Door unlock (normally closed) - not used*
*These wires arent needed on my application . Got this info from another BMW owner with same year/model car and a Clifford alarm (cant contact him for this question).
Where do the "common" wires attach to on the car or are they needed? Thanks.
You need to find out which polarity you are working with, - or + . If it is - then conect the common wire to a - source and the normally open wire to the lock or unlock wire. The switch will close and create continuity between the common and the normally open switch when activated, but normally the switch is open. If you find the lock and unlock wires, you can back probe them with a test light. If they activate when you touch them with the test light and you have the test light on a ground source then you are working with the - side. If it is positive you can do the same thing, but try the negative first.
