When I start my truck and shipping the engine light doesn't come on and sometimes when it's on, you're driving down the road it goes off, that loses your heat, and cruise control. I don't know what else, I just changed the ignition module because the gauges were not working and now this is a problem.

This is common when the ignition switch goes out. To be sure, here is a guide to help you to test for power at the brown, yellow, pink, and orange wire with the ignition switch on. You should do the test when the gauges etc., are not working.

See how the system works by clicking the image ignition wiring diagrams below. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
