Most of the green wires are switched 12+ (except the one in the top left corner, that is RPM in from the VR sensor)
The red wires on the outputs are drain wires on the mosfets, the blacks are the power-grounds (source).
Thank you sir. When I got the engine running I'm going to hotglue all the small wires to the board to prevent them from breaking off because of vibrations
Only got the MAP and VR input left, but I'm going to test all the inputs/outputs first now.
After the testing I'm going to connect all the wires to the Motronic 55 pin connector to regain some structure in the view...
