The BMW Electrical Troubleshooting Manuals (ETMs), linked to above, are drafted in a simple, uncluttered style for automotive technicians. Engineering drawings are almost always much more dense packed, and to a layperson, probably much more cryptic.

The first couple sections of each manual (0110 and 0140), after the index, explain how to interpret the drawings. (Different automakers have different styles). Sections 7000 and 7100 show component locations. The BMW ETMs are pretty well organized – is just takes a little time to get used to BMW's style.

For laughs, I have attached a schematic I was studying a few weeks ago, that helps engineers design in a simple voltage regulator. I only had to understand the bits near and around 2 1/2 sides, to answer the question: just how many pins can I tie to ground?
