Haha!Do you have any aftermarket powered accessory in that vehicle particularly tapped to the fuse box or any circuit?
If you do remove that before you try anything else.
I had no rear defroster and it turned out that I had my backup camera tied to the cluster circuit and that was confusing everything.
You can cross one wire on a TJ and flash your lights and it will change the channels on your television.
No nothing that I know of wired through the fuse box. 3 sets of lights just wired straight to the battery with a relay and it’s own fuse.
