When I pull my headlight switch out the lights won’t come on. They only come on after I turn the key to the ON position. I tried the old headlight switch in place of the new one just for giggles and it does the same. Have I crossed wires somehow at the ignition switch?

I using an American auto wire universal wiring harness on this truck.

Thanks!
