1) Yes, please.

2) I'll have to see if I can't dig up my 1985-1986FSM - it's around here somewhere. I've just got to find the wretched thing...

3) The wiring for the ignition switch should be about the same - IIRC, it's a standard GM colour code.

4) Did you switch to a "tilt" ignition switch at the same time? The 1990 FSM does not differentiate between functions for the wiring, so it's probably not an issue. But, the mechanical operation of the two styles damn sure is different, and that might be causing you a problem you're not aware of.

I'll PM later - I've got a few things I've got to see to beforehand.
