The Bentley manual, Chilton's and Haynes all have wiring diagrams, all are
incomplete, and all cover slightly different aspects of the electrical systems.
None of them cover such simple things as the interior lighting.  None of them
tell you what all the leads are to the instrument cluster or OBC, for example,
although I was able to figure it out by combining snippets of information from
all 3 books. Of the three, Bentley's is clearly the best, so if you can afford
only one manual get that one.  If you really need a complete set of wiring
diagrams you'll have to spring for the ETM (about $135 or so, if memory serves).
