Thanks for the reply, I'm actually looking for everything. Got a new truck and it doesn't have gauges and the heater control, and all dash components are not installed correctly. The headlights also will not stay on., sounds like a grounding issue. I have never worked with wiring components in these trucks. Just looking for a base to start from.
