All my lights work but the tail lights. I have brake and front runners and turn signals. And I tried stephygee.com thanks, found stuff I needed but not wiring solution. Thanks for the quik responses I just wish somebody knew what wire or plug to look for.

 

I'll probably sound dumb saying this but did you check the wires around the connecting point in the back? Maybe the running light wire got cut somehow. Not sure exactly what color it is, but just look for split wire(s) and OR wires grounding themselves out..

Never really had this problem so I'm kinda shooting from the hip hoping to hit the problem lol
