PIA to get at with headlites in, passenger side wiring comes in to front side of washer bucket , driver side come out about 1/3rd way down along side radiator. You can jiggle them around to see them, good luck unplugging them in the tight space.
Got mine apart and cleaned up followed with a good coat of di electric grease, come apart real well now .
Did wire my side marker to turn signal wire, pretty cool to have a side blinker on front, haven't done back...yet !
