Jeep Wrangler TJ Factory Fog Lights - Enabling Their Use With High Beams
and
KC Hilites Quad Beam Conversion Kit

Enabling your fog lights to stay on with your high beam headlights. If you are the type of driver who wants more light on the road when using your high-beam headlights, follow these instructions to enable your factory fog lights to illuminate with high-beam or low-beam headlights.

2001 - 2006 Jeep Wrangler: The Jeep Wrangler TJ factory setup, as with most vehicles, turns off the fog lights when the high beam headlights are turned on. To have the fog lights stay on with the high-beam headlights on the 2001 - 2006 TJ Wrangler, follow these instructions:  Find the #35 fog lamp relay inside the main fuse box, which is on the passenger side of the engine, under the hood.  The relay is clearly marked on a diagram on the inside cover of the main fuse box.

Pull the relay straight up and out of the socket. Carefully and slowly bend the #1 pin (it's marked) 180 degrees around to the side of the plastic relay, so it will not make contact with its female socket when the relay is re-inserted. Re-insert the relay and you're done. You can now turn on the fogs with either low beam or high beam headlights.

1997 - 2000 Jeep Wrangler: On 1997-2000 Wranglers the relay is located behind the glove box door. You remove the glove box door and pull relay #2 (the one on the right) and bend pin #1 (it’s labeled.) Put the relay back in and test. If you have no fogs you pulled the wrong relay. Just switch them and it should work.

KC Hilites Quad Beam Headlight Conversion Kit, for those who want more light when the bright headlights are on, it’s part #6314 at KCHilites. This kit allows the low beam headlight filaments to stay on along with the high beam filaments, when the high beam headlights are activated. The TJ factory setup turns off the low beam filament when high beams are turned on.

KC claims this kit is for most pre-1999 vehicles only, but as long as your vehicle does not have high beam day time running lights, it will work fine. It works for 2-headlight systems and 4-headlight systems. I installed this kit on my 1994 Chevy Van, 1999 Chevy Van, 2002 Jeep Wrangler and 2006 Jeep Wrangler. Easy installation and it works great.  

Available at KC Hilites, Amazon and many other retailers.  Installation instructions for the #6314 kit
