Also, and I feel you on the need for pictures, but when I was wiring my 84 CJ7, I went and bought a cool book on automotive wiring. At first I was afraid I wouldn't be able to follow it, but the author used pictures and made it very readable to normal people. It wasn't a sole source or anything, but it was a hell of a primer that let me get the basics of the harness and what does what and why, and then I had a LOT more luck with being able to follow diagrams and whatnot. I think the whole thing was maybe 100 pages, but like I said it was very readable, got through it in a couple of afternoons and it made a world of difference if you're just starting out with wiring.
The book is "Automotive Electrical Handbook," published by HPBooks, and the author is Jim Horner. I think I found it on Amazon a couple of years ago, now it's well-worn and highlighted. If you're looking for a broad-overview starting point, this has worked for me.
Good luck man!
