I have the haynes and it sucks. All I have is just the basic mirrors, no heat, flashers etc.
The problem with ts without the drawing is this: Everything is plastic and there are no clearly labelled hot and ground. The switch mounts into a plastic panel that snaps into the door. There is 2 black leads (1 has a white stripe) and no red leads. I can't really tell which leads are for what.
Next week I am going to try the local library, but the last time i looked they just had general repair info. Nothing specific.
