HOW CAN I IDENTIFY THE WIRING HARNESS ON A 1997 GMC 1500 SINGLE CAB TRUCK. AND IS THERE A WIRING DIAGRAM THAT LABELS IGNITION 1, IGNITION 2, IGNITION 3, AND ACCESSORY. IM TRYING TO INSTALL A REMOTE START ON MY TRUCK, ITS A PROJECT TRUCK THATS WHY I WANT TO DO IT MYSELF INSTEAD OF TAKING IT TO A SHOP.
if you go to the web site for the system you bought they should have diagrams for you truck, or go to a radio shop and they may give you that diagram.
