These are scans of the color wiring diagrams out of the back of an old Clymer BMW Manual.
The diagrams cover the wiring of bikes from 1970 to 1982.
I left the pictures rather large, about a half a meg (500K) each. I figured that if anyone wanted to print them, or really study them it would be better for them to be too large than too small!
The most heavily used ones are soiled a bit, and written on, (1970 diagram) but should still be perfectly usable.
