I drew this diagram for my K100 RT 1986. Dark green, light green and brown wires are part of an original installation that I do not interfere with. Anyone have any suggestions, warnings, confirmation, that I think right. Today, I got the last elements, so that I will finish the project in a short time. I would also like to ask: will the 1.2W diode be OK?f

This doesn't look right at all.

There is a schematic posted here: https://www.k100-forum.com/t11686-m-unit-wiring-bmw-k
