I added a page,  61 BMW R75/5 Removing the Wire Harness & Electrics, showing how I removed the wiring harness and electrics.  I took detailed pictures of the wiring layout, labeled all the ends and made some sketches so when I reassembly the wiring, it should be a lot easier.  Here are some of the pictures.
