At one time, I turned the switch on, and all the lights worked. Brake lights worked, parking/running lights worked. I checked it for a couple of days, then about the third day I turned the switch back on, they didn't work again. I'm stumped.
I really appreciate everyone's help with this. I'll use this weekend and start testing everything and tracing wires. I'll even check the electrical issue 😁 Again, thanks everyone.
