SHobbs, when you remove the headlight switch you will find that the harness has a short pigtail on it, it may be stuffed inside a bit, that will plug into the extra spot on the new switch. If you buy the dodge kit you can use the harness and relay and other parts for other projects. When I priced it the kit was less than the seperate lights, bezels, and switch by quite a bit so even though you don't use it all it is a better way to go. Good luck.
