I finally sat down and finished the wiring, it took me about two hours to do since it was my first time to wire an electronic ignition CB750. I have done a few viragos with EI systems and I can do them pretty quick now. The CB750 was more complicated because it has two separate TCI units. Here is the simplified diagram that I found and used. Gotta love the internets!
I know it looks like a lot of wires but it is really pretty compact since that’s all the wires on the bike, that will all be under the gas tank of course.
I just used one main fuse between the battery and key switch. The master cylinder I installed has a brake light switch built in, so I wired that into the harness so the front brake will trip the brake light instead of the rear. In the past I usually just use the rear switch but it doesn’t look as clean and generally riders use their front brakes more than the rear so it is a bit safer this way.
If you look close you can see that my ground-to-frame is about 2″ long which is awesome 🙂
On an unrelated note, I was walking to go get the mail and as I passed my girlfriend’s parked car something bright white caught my eye below the steering wheel. Upon closer inspection I found this!
Here i’m staying up all night wiring motorcycles and Jazzy is just snoozing in the car! What an easy life.
