It's been on mind for a while and I wanted to redo the wiring on an R80 project that I'm currently renovating, and decided to use an m-unit that I had kicking around.
One thing which I found difficult, was to find definitive information on how to wire it up specifically for a BMW and how to get the charging light etc hooked up correctly.
For this project I wanted to keep all the stock controls for the functions of the bike, but redo the wiring so it is simpler and more robust than the original.
As I couldn't find anything around on the web which looked close to a wiring diagram for the stock BMW airheads, I decided to draw one up and share it. Hope fully it will help someone out.
