I am having a problem. The #1 and #2 upfitter switches are wired up to the KC lights and bar from Ford Racing and worked as they were ment to for about 2 weeks. #1 switch 2 driving lights, #2 swithc to 2 longe range lights and all worked. Now both sets will not come on. I checked the fuse in the 37 position in side the kick panel and it looks OK. I am at a loss. The only other common item shared by the 2 systems is the 4 ground wires are connected at the same point with a bolt to the frame. I have checked every thing amd all connections are tight and no broken wires. I looked at one of the fuses under the hood and as far as I can tell it is OK as well. I swaped around a relay and replaced the 30 amp fuses but still nothing. I dont see 2 seperate systems going down at the same time. Can any one help or should I take to Ford?
