I just installed 5.5" driving lights to my front bumper on my 97 Cherokee. I want to splice them into the existing fog lights that are burnt out. Basically I want to use the existing switch inside instead of drilling a hole for a new one. Any suggestions?
Driving lights are usually for offroad only, or to be wired in with high beams to make them brighter on back roads. If you use the stock fog light switch, the lights will only come on with your low beams. The factory fog light harness is also pretty cheaply made with tiny wires. I wouldn't trust it with big high wattage lights.

there's no need to drill new holes, just run new wires through the existing holes in the firewall. I just finished the wiring for driving lights tonight, it's not hard to do, and you'll end up with a beefier wiring set up for your driving lights.

Just run new wires to the old fog light switch through a relay,its pretty easy to do and it works well I have two 100 watt lights on my bumper wired this way with no problems.
ah,beer the cause of and cure to all of lifes problems ...Homer J Simpson... I am the guy in the red jeep!
Wire up the new lights using a 30 amp relay run a wire from the fogs the the switched input on the relay(4 post relay- power in, switch in, ground, power out to new lights.) be sure to put a 25 amp fuse in the power in wire to the relay. This setup will utilize your exsisting wiring and will keep all of the new wires under the hood.
