This bike has been quite the project.I have been working on this bike for over a year and have not yet ridden it more than 1 mile.  I had it running and it idled awesome but when I would drive it, it would stutter during the first 3rd of the throttle. I had just moved from DC to Marin County in CA, and I do not have tools, a place to work on the bike, or the time to work on it much. I found a guy on craigslist and he helped me out and cleaned the carb, rebuilt the accelerator pump(which was in pretty bad shape), and replaced the coils and wires(which were also in bad shape. He was super nice and things were just about done and then he replaced the carb and saw two wires that were loose. I had thought they were the horn but apparently the one wire was getting consistent hot power and seems to have fried my starter solenoid. The bike no longer is getting power and should FINALLY be able to run correctly but I can't try because some of the wiring got screwed up. Here is a video of the guy who helped. Any advice on what theses wires go to would be greatly appreciated.

Those are NOT standard connectors. I would speculate that he had something aftermarket rigged up. Trace them down on the other end and probably eliminate them. That's my 2 (per) cents.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

Not sure about the wires in the video, but the green wire attached to the nut in your picture is used for grounding (earthing) your front turn signals. They fit inside the headlight shell and the turn signal stem bolts in to the nut, with the green wire connecting to any other green harness wire inside the shell as part of your earthing system. There should be two of them.

This might help in tracing the wires. It is never a good idea to intentionally spark a known hot wire multiple times.
For any reason.  Best of luck!
