Back in this thread, 430461, I asked for recommendations on wiring/electrical books. Midlife suggested Auto Engines and Electrical Systems, Blanchard and Ritchen (published by MOTOR). I just got it and it looks very good (700 pages with lotsa pictures). It covers more than electrical systems as the title indicates. It was also cheap as I got it used through Amazon's zShops ($15).
