I know this is an older post, but hoping someone will read this and shed some light on my idea. Both switches have the same amount of pins. since both switches have 7 pins, wouldn't it be easier to figure out which pin does what, then change them around. Im not an auto elec so Im not that good at figuring out which wire does what, but I am pretty good with moding stuff. My theory is, take a look at the VT headlight switch connector plug from the car and see what colour wire does what, then cross reference with the VS headlight connector plug from the car. Or maybe even using wiring diagrams from both cars and cross reference that way? Because the pins can be removed from the factory connector plug, (albeit tricky as buggery trying to get a needle or some such tool to pull the lock in tab that keeps the pins in place) but still can be done. and personally I believe it would be MUCH simpler doing the mod this way. So if someone who has more know how in figuring this out, could you please shed some light on which pin would go where? as this would make this mod. a lot easier I think, plus give the added advantage of not having to make a spot for the interior light (no offense but I think it looks ugly like that).
