To make a short story long does anyone have a wiring diagram and color code for a 1989 GMC Seirra Pick-up (2 door) and 1995 BuickLaSabre with details for adding truck release.

I tried the red and blk wire, and lt blue for door locksand it did not work. Could I have something else screwed upI used a jumper wire to check door locks after I removed door panel and it would not activate the starter works but door locks don't. I do thank you so much for your help.

You have a 5 wire type C system. Use this diagram with two relays to activate the door locks:
