Anyone have an alarm wiring diagram for a 2004 chevy express?

I installed an old alarm, but the lights dont flash and I couldnt find the wire for all the door contacts.

thanks.

The park lights are brown (+) in a harness running under the drivers floor. Pull the carpet/rubber flooring up a little and you'll see a harness where the drivers feet go. Bunch of brown wires so be sure to test it. As for the door trigger I usually only install keyless entries on these, but the drivers door trigger is a thin tan (-) coming in from the driver door.

FROM DEI:

The front passenger and rear cargo trigger is light green in pin A5 @ the BCM, and the rear door trigger is yellow/black in pin A10. Use all three wires and diode isolate each.

Or you could take the easy way out and pull the domelight..

So I could get the dome light at the headlight switch assy on the dash?

I think I used the thin tan wire coming from the driver door, but only the driver door worked.

I dont know, I need more time to look at it. I can wire a bank alarm, but this just threw me today.

I will look for the parking light wire under the rubber mat.

Do all of these wires come together at the driver door molex or do I have to get a wire to each one? And, do I have to isolate them? I just want the alarm to go off if any door opens, I dont care which one.

OK I found the parking light wire and the door trigger wires at my feet.

So, Do I have to isolate all the door triggers? Using what diode?

I just want it so if any door opens, the alarm goes off.
