Would anyone have this information on the wireing of the BCM? I'm trying to install a DEI bypass module 555L for my Valet Remote starter 552 T (also made by DEI) And I have to get the resistance from a wire connected to the BCM, but I dont know which one it is... anyone have a wireing diagram or a list of wires off the Body COntrol Module? Please if you do? E-Mail me jdthiele@hotmail.com Thank you!
