Since I have the entire under-dash wiring exposed on my 1991 Donor, thought I'd post a few images of the fuse panel, since the underside is very hard to get to without (a) pulling the dash out and up a bit and (b) dropping the HVAC controls as well. A cover has to be removed to access the wiring underneath.
See this thread (on installing heated seats) as an additional reference. I decided to pull IGN power directly from the fuse panel wiring but in retrospect I'd have been smarter to use a fuse tap.
