My heating system doesn't work and I suspect it's a bad ground or something likewise.
In order to fix it I colorized the wiring diagram for the body electrical system.
It's a diagram out of the Owners Workshop Manual from Autobooks. I don't know for which countries or years of manufacturing this is relevant.
The book says: BMW 2500, 800, 3.0, 3.3 Saloon, Coupé, Bavaria, 1968-1977.
I hope it can be useful for others working on their wiring.
Maybe in the future when I feel like it I will colorize the other diagrams as well.
