Incorrect (at least on my car). See the wiring diagram. The "V" wire exiting the bulb of the dome light is white/black on my car. It comes from the Fues block and sure looks hot to me, and was hot when tested. When you ground that, the dome light lights up. What isn't HOT about that? Whatever at this point. Mine works as it should in all 3 positions and I am moving on.
Larry - agree with you, the switches are all over the map in terms of which terminals they have, and whether they connect in a given position. The only way to determine is to test a switch in all positions to see which lugs are connected. From that you can map how to connect the device or lights properly to make the switch do what it is supposed to. Simply attempting to stick wires on a numbered terminal will not produce the result unless you happen to get lucky.
