2003/04 Silverado Alarm/Remote Start Wiring

The 2000 is the latest on here I can find, does anyone have any information on the new wiring diagrams, for the 03 or 04 models, or even the 02..? Need the Lock/Unlock wiring colors, as well as everything else I would need for the install of a Remote Start/ Alarm System, 2 Way Audiovox LCD Alarm.

In a short sh*t... need wiring diagrams for anything from 2002-2004 on Silverados. w/ or w/ out the Keyless entry module color codes.

ANY HELP WOULD BE EXTREMELY EXTREMELY Apprecciated. Thanks :-)

2002 - 2004 Constant 12v = Red @ Steering column Ignition 1 = Pink (Necessary) @ Steering column Ignition 2 = White (Necessary) @ Steering column Accessory = Orange (Necessary for ac/heat) @ Steering column Accessory 2 = Brown (Usually Optional) @ Steering column Starter = Yellow @ Steering column Horn = Black or BLACK / YELLOW (-) @ Steering column Brake = White or light blue @ brake switch Park Lights 2002 = Brown (+) @ BCM 2003 - 2004 = Gray/Black (-) @ BCM Locks 2002 = Light Blue (+) = Lock @ BCM 2002 = White (+) = UnLock @ BCM 2003 - 2004 = Use a databus module Passlock 2 2002 - 2004 = Use a databus bypass module Hope it helps, Mike

Thank you very much, I just picked up the databus module for the door locks, for 40 bucks, and I have the passlock II module.. The Alarm I am installing is the AudioVox APS 996C. If at all possible do you think you can come up w/ a diagram or schematic on how the passlock II module needs to be wired w/ the Starter Ignition relay, Im confused w/ this matter now that there is 3 ignition wires that have to be dealt w/.  Anything you might beable to draw up for me would definately help. This is a 04 Reg Cab Silverado Base model, and I would hate to have to find crap out the hard way. I have everything else figured out, I am just not 100 percent sure yet of that passlock II wiring.  Any more help would be seriously appreciated, I wouldnt even know what to do w/ myself if you could draw up a schematic for me on that issue. Hehe. Thanks againKyle Newton

I am also a little unlcear of the Purple Start Wire, which is the wire that will prevent the car from being started in gear. I think all it means is that the wire must go on the engine side of the starter wired.Kyle Newton
