I do not have the wires that are supposed to be in the BCM to use for door triggers. I have a 2003 Chevy Silverado 1500, ext cab, z71 LS. So if anyone has any ideas, please let me know. Thanks all.

Uh he stated door triggers not locks but for triggers here you go:

On base model trucks the door trigger wires are in the lt. blue plug at the BCM, pins B4 and A5. On 4dr trucks the LR door trigger is lt. blue/black, pin A3, and the RR is lt. GREEN/ black, pin A2. They are in the purple plug at the BCM. Use all wires and diode isolate.

Someone pass me that bottle.

I appreciate the help guys, but I don't have the wires in B4 and A5. I had the wire colors, but there just isn't any wires in those spaces on the BCM. And I do have the Databus module, but as Ruf said it doesn't help with the door triggers. I'll have to keep digging I guess.

Ive read of catching them in the doors. If Im not mistaken Blk.wht in the drivers door??? Pass door and others Im not sure. Go to the latch in the door as sometimes the answer is there.

yeah, i'll have to wire into both doors i think. Apparently because the DDM houses the keyless entry system, it only sends and receives Serial data, and doesn't have a wire dedicated to just the door pin switches. I wonder how long till one of the aftermarket companies figures it out, and incorporates the triggers into the Databus modules for the doorlocks. I wish i could figure out how to dup;licate the serial data, could do all sorts oh neat things then.

Yeah---Its kinda like a Duraflame. It was sparked but not fully lit until an hour later. At least I was warm. Good looking out Sparkie. No pun intended 2003 Silverado door Triggers -- posted image.

ok, gonna tear into it today. Thanks guys. I'll post my findings or missings for that matter, LOL. My silverado really cracks me up, of all the vehicles I've worked on it is the easiest to pull apart(dash,doors, etc). But try to do any wiring in the truck, and it's the most difficult I've ever dealt with. Oh well, evolution at work.

I was also looking for the blue plug, so its on the bcm? Thats the module under the knee bolster on the drivers side right? You need to isolate with 2 diodes also right?

Want to know about Audi, I thought you did.
