Light switch or back up light wire
 

Seem to have terrible luck when it comes to wiring... My light switch doesn't work quite right, my dash won't dim. My main concern is my reverse lights stay on, I'm wondering if the reverse light wire, running from the transmission has grounded itself somewhere or if my switch is just messed up?

The headlight switch doesn't have the reverse lights run through it, so that's not the cause. I would start by checking the switch on the transmission and the wires running to the lights. Good luck!
