I ran my wires outside but on the inside of the frame, I also used that plastic housing....what ever you call it?
I ran all the way to the battery with a fuse very close
to the battery, this was from a switch in the dash,
I just drilled a small hole for a switch.
I had a set of Off-Road lights off from a Jeep TJ 1997-2006 (same)
These lights are dam near perfect the stud on the lights
fit the nut of the cage, just added jamb nut for proper addjustment. /forums/images/graemlins/cool.gif
Oh did mention they are bright!
I wired to the battery so the lights can be run without the key on, if needed.....
Be sure to use a fuse right near the battery, if ya go this route
FWIW lights inside the cage may bust you in the head?
Lights outside the cage may catch a tree branch?
