anyone know where to pick up a good manual for the wiring in the 8? Hopefully one that's comprehensive and easy to decipher.

That's not the complete wiring diagram, though. ........

What's missing from the PDF that's in 9999-95-040G-04?

I don't know, as I don't have the separate wiring diagrams. A few members who have both manuals have confirmed that the separate wiring manual is more comprehensive than what is in the basic manual. Of course, the basic manual is a good start, though. It has more than I would probably ever need! :)
