Hi there, I leave here the wiring drawings of a CB750 SevenFifty RC42. both on original and the color tracing I did manually some time ago, in both jpg and pdf. Hopefully useful for you out there, it helped me a lot to figure out the way the bike is connected to make mods. For the colored wirng diagram, I think is best printed from the pdf in a 135% scale to 4 A4 pages (original file is A3).
