Have a e50 with the 6wire setup but the wiring was all messed up when I got it. I've seen a lot of diagrams but nothing that lines up quite right. I have all the wires out of the stator and all stock head/tail lights, horn, speedometer, etc. which I would like to get working. My light switch is confusing me though, from my picture, yellow is going to stator yellow and gray is going to the horn/blueblack. Should I add another wire based on the diagram to connect Lo to the headlight? Also where does it hook up to the rear light?
