I put some information together about the Hitachi Carb wiring harness and the 720 harness. This will be very useful in a Weber conversion, especially if your carburetor is missing its harness, has been replaced with a different year carb, or is missing the wiring. This write-up focuses on the choke and anti-dieseling/cut-off solenoid. I will add the other wire descriptions if I find them. Feel free to post any related information, and I will update the drawing. I hope this helps someone and saves them from the nightmare that I had!
I added the image from service manual as another reference for the anti-dieseling solenoid.
I think this would be a helpful edition to the DIY section.
