Just brought my new (to me) 99 TJ home and was fixing a few things for safety. I did the front brakes which went smoothly and have started on the little things. One of which is the drivers side tail light doesnt work. it lights up fine when the brake is applied but is a no go with the lights on.
I figured it was a simple bulb, however, when I took the tail light cover off I noticed a brand new bulb. I swapped the bulb anyway and still nothing.
I have noticed that the PO installed a trailer brake extension and he hacked into the wires just inside the tailgate. I noticed that coming out of the light bulb are a purple wire, a black and (yellow i think) and a green.
anyway im hoping that it is as simple as cutting the trailer harness out and reconnecting the wires.
