Here is a schematic I worked up of the internals of the typical 
underhood fusebox:

The rest you need ought to be in the appropriate Bentley - surely you 
have that by now - unfortunately the "later" Bentley manuals spread the 
diagram for one car out over a *lot* of pages (as opposed to the 8-10 
pages for, say, an '85).  Every system seems to get its own three page 
spread.

As far as the engine bay diagram, you can sort of piece that together, 
as each "system" in the Bentley usually has a crude drawing or two 
showing the locations of components.  It tends not to show where the 
harnesses lay out, though.
