Thank you for your reply! I'm sure the high load causing issues is what's going on, which is why I wanted the harness. I still have yet to check the actual switch, but when I installed the harness relay kit, it smokes the relays in it when I hit the dimmer switch. But it doesn't smoke the relays...
Thanks for your replies, guys! I'll dive into it hopefully sooner than later because I need to drive this rig at night. I'll keep you guys updated as to what I find, it might be a little bit before I can get to it though! Thanks everybody!
So I have a 91 and a 94 XJ in which I installed Hella H4 housings and Sylvania Ultrastar bulbs with the headlight upgrade harness from K Suspension on both vehicles. Works flawlessly!
I also have a 96 XJ where sometimes the headlights will shut off and I hear a click behind the gauge cluster...
