Sounds like you don't have a ground. The factory lights were grounded through the mounting bolts.

That's exactly what it was bud thanks but now everything works but the brakes I'm thinking brake light switch under pedal?

Possibly. You can check voltage at the switch when pressing the brake pedal and also check it back at the wires also while someone is pressing the brakes) Check all fuses under dash and hood if no power to switch or back at the wires.

In the 87 yj 4.2l are there supposed to be reverse lights? I find it odd no lights come on the back up...
