On my truck the gauge lights do not work. I have looked at the fuse and it is not that. I have put a new radio in and I had to rewire the radio so. The radio works but not the gauge lights.

Hello,

It sounds like the headlight switch is not working but to be sure here is a guide and the dash light wiring diagrams so you can see how it works and run some tests. Check for power.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken
