I rewired my KCs. I had a problem with switch on the steering column. My fog lights would randomly turn on leaving me with a dead battery.
If the stock fog light wire is as thick as the KC lights I would thing you would be fine but the thing that concerns me is the stock fog lights were only 55 watts, you KC light are probably considerably more than that.
