does the stick for your lights have the option to turn them on? I have a 09 Rubicon and to turn the fog lights I pull out to turn them on at the same time I rotate to turn parking lights on.
I seem to remember that there were a couple options for this switch and if yours doesn't have it then I highly doubt the wiring is going to be there. The lights in a JK are controlled by the computer.
That being said it wouldn't be too hard to wire up fog lights with a switch in the cab.
