I had a hitch installed along with the wiring on my 99 classic about 6 months ago at an aftermarket store. I have only used the hitch a few times and noticed that the lights on the trailer worked, except for the running lights (when I put the headlights on in the cherokee), no biggie, I just didnt tow anything after dark. Recently I noticed my left side parking lights (front and rear, right side works fine) did not work, but the turn signals and brake lights work just fine. I replaced the bulbs and checked fuses and still no luck. I then noticed my hitch wiring had burn marks on the harness that plugs into the trailer harness. When I took off the left brake light, I saw the person installed the wiring by tapping into the left factory brake wires (one wire went to the right side rear brake light). After researching a little more, I noticed that the cherokee requires the wiring with the "black box", but I could not find anything installed on mine. I searched the forums and found similiar issues to a bad ground, but I think this may be more then that, any suggestions?
