i have a '00 xj sport without factory fogs. i want them. i can get a factory switch for like $10. when i pulled to dash apart to see how hard it would be to put them in, the wiring was plugged into the blanking plate where the switch should be. would it be safe to assume that all of the wiring is there and i would just have to mount the switch, lights, and a fuse in the fuse box?
