Joe's Answer
William asked:
"Hello Joe, I have one of your Taillight wiring harness 68 Shelby & GT/CS Item # 3643MF. I purchased it back in Jan from Mustang Unlimited and installed it today. Everything works as it should except one of the 6 lights will not function. The outer most light on the passenger side does not function. Said another way - the light on the far right (as you are looking at the back of the car) refuses to work with anything - i.e. no brake, no turn, no tail light. I have switched bulbs and that is not the problem. I have also taken the plastic cover off the wires and there does not seem to be any breaks in the lines. Any thoughts would be greatly appreciated. Thank you! William"

I would contact Mustangs Unlimited and arrange an exchange. Sounds like to me you have a faulty harness.
