Oddly enough, I was going to mention ignition switch, but I've been a bit pre-occupied.

I have a copy of the microfiche thing in PDF, if that helps. It's got some indexing to make searching easier. It's what I use, a lot. It was originally from someone on here.
If you want a copy, send me pm with an email address, and I'll attach what I have. The only downside is that it is American market, left hand drive, so some extra thinking is required for the uk market differences.
