I've been doing some searching in prep for putting in the harness and thought I'd post links to two threads out there.

Talk to me Turbo Guys This one has the Monty side of the B38/B37 hookup.
Turbo wiring question (almost finished).

There are also some good links in them. One links to someone's (Liz?) "modified" wiring diagram that also shows the coil hookup.
