I had the same "problem" on my YJ. I finally gave up and since I was replacing my OEM fogs with LED fog lamps, I wired those as daytime running lights and they automatically come on no matter what the headlights are doing. I wired them through the fog lamp switch (with OEM wiring removed) in case I ever want them off. Everything seems to be working fine. Replaced the halogen headlights with LEDs also, WHAT A DIFFERENCE.
