just joined today and have a question about wiring diagrams. I have an 03 ltz 4x4 that ive owned for several years now and I was wondering if anyone could tell me where to find a wiring diagram for the ignition system. It started having intermediate no crank no start issues a few months back and I want to resolve the issues soon. im pretty sure its the switch but I would like to check other possibilities while in in there. thanks.
