It is a 1989 Pontiac Grand Prix. I have a Chilton's manual, but it doesn't contain the necessary information. It is a thick book covering all cars from that year and not one specific to the car, if they make that.

I was googling "1989 grand prix vss wire color" and a few variations on that, but I just tried what you suggest and I get nothing useful. There seem to be things for cars just a few years newer, but not for mine.
My question, I think, is a more general than this, though. I'm pretty sure I have it narrowed down pretty tight, but I want to know what I'm looking for. Is there one wire to tap for each signal? What kind of signal does the wire have, so I can confirm that I have the right one?
Oh, and...is there a wire that, if grounded, can destroy an injector?
