I've had the Service Manual for every care I've owned in the last 15 years. I went scouting around the web to order one for my new 2007 530xi, and I cannot find such a beast. Lots of manuals, but for older 5-series, not the E60.

At the moment, I'm interested in the electrical wiring, and how things are wired through the fusebox (A schematic would be wonderful).

Where do I go to find such things?

 

I've seen some on ebay.com

 

you can get the CD from ebay for $9+shipping.
