So im in the process of moving. I bought a trailer a few months ago and i basically rebuilt it. The Po of the xj added a 4 flat connection and a hitch and the wires come out from behind the spare tire. i hooked the trailer up cause all i had to do was wire the lights. I had the lights on for a second, but i must have bumped the wire on another and it wont work. I cant seem to find a fuse for it. there are a few wires plugged straight into the fuse box. Could there possibly be a in line fuse? I really dont want to have to take all the door trim pieces off to try and follow these wires. what would you do?
