Taillights dont work
Yes sir, I too have had this very problem a few times. I would like to recommend a solution that I have had to use. Under your dashboard and at the top of your brake pedal is a switch so that when you push your brake pedal, the brake lights come on. Find that switch, you will need to start from there. Find a way to get a testing instrument, and test the two wires that go to the brake light switch and see if either of them is "hot" all the time. One should be. ( Your brake lights should work all the time, every time you push the brakes, engine on or off.) After you have found the switch, if neither one of the two wires is hot all the time, you will need to find out which wire goes to the brake lights. Take a jumper wire to the battery plus ( +) terminal and touch the two wires that go to the plug on top of that brake light switch and see which one lights your brake lights. If you get the brake lights to work with that jumper wire, you are halfway home! Oh yes, you will want to push the brake pedal to test the switch with the jumper wire attached.
Let's hope one of those wires will light the brake lights when the hot jumper wire is attached. If so, you could run a wire from the battery to the brake light switch so it will work all the time. You need to add a fuse holder and fuse to that wire to protect the circuit. They sell these in car parts stores. It is a about 8 inches long and has a white plastic fuse holder in the middle with a fuse in it.
If one of those two wires to the top of the switch is hot, then either the switch is bad, or you have a break in the brake light wire. I would find a test instrument and see if juice is coming to the other wire, (not the hot one) out of the brake light switch when the pedal is pushed. In that case, you might run a jumper wire from the brake light switch to the back of the jeep and splice it in to the brake light wires. You will need to identify which wire goes to the brake lights in the back of the jeep by color code. and I would cut the wire coming from the front, since, as you say, the wire might have a short in it. Be sure you have the right bulbs in both brake light sockets, because the wrong bulb can cause this problem also ( Using a one filament bulb where there is supposed to be a two, or visa-versa.)
