I've been attempting to track down the parts to try this out, I ordered one headlight switch for my 2010 Fusion SE (Motorcraft SW-6602) and it wasn't the right size. I also ordered a Sun Load sensor (DG9z-13A018-a) which looks like it will work but I can't seem to find the wiring harness for it anywhere. Anyone have a reliable/easy place to find the correct parts. It seems no where has accurate pictures or descriptions. If anyone had the part #'s for a 2010 i'd appreciate it. I don't want to order the wrong thing again.
