I have a 1988 Jeep Comanche Pioneer (5 speed manual, 4.0, 4x4) when I got this truck the brake lights didn't work, turned out to be an easy fix, i just had to rewire the connection to the switch on the brake pedal, but as i was bolting it back on a small amount of smoke started coming from under the hood, i quickly shut off the key (i know, it should have already been off) and popped the bonnet to find smoke, the smell of burning rubber, and no apparent damage to any wires or connectors (inside or out) that i could find. However, once i climbed back inside i realized all electricity that passes through the cabin was DOA (no radio, fan, turn signals, break lights, starter motor, or wipers, but the headlights still work) i dug through the wires up front again and replaced any questionable fuses (they were really old and a little corroded, but none were burnt) and i took the cover off from under the dash board and looked through those wires to no avail, they all looked healthy, any thoughts?
Personally i think that it must be something through the key, as it continually acts as if they key were off, but as i said, i couldnt find an obvious short and the smoke was coming from under the hood, over by the wiring box (or where it should be, due to an engine fire a couple years back i no longer have a box, but it was repaired by a mechanic and has run ever sense)
If no body has a suggestion i will have to take it to a mechanic, but i would much rather fix it, unfortunately the body of my expertise falls outside of electricals
