Thanks
@kirrbby for the tag. I only visit every few days and hadn’t seen this post.
The wiring harness picture:
As Kirrbby said, the three plugs in upper right of pic go inside the headlight and probably has more wires than you need. Which wires you use will depend greatly on the type of switch controls you run on the bike. In the left plug, I do see a black/white wire, which is usually the “kill” wire. Whatever this harness was made for, the key switch must have been in or very close to the headlight.
Heading down the harness, to the left, the next plug connects to the wires from your engine, just match colors. You say you have a black/white from engine…..are you sure it’s not blue/white? Regardless, hook it to the blue/white in harness. I don’t see a green ground wire in this harness plug. The green from the engine will need to go to ground.
The next white plug is for gear selection indicators. Your engine probably only has a neutral indicator wire, which is the green/red wire. Hook it to the green/red in this plug. Ignore the other wires in this harness plug.
You have the next two wire labeled correctly, they go to the 12v coil.
The next wire with eyelet looks to be a chassis ground.
If the next two wires are black and green/yellow, I would say you are correct, these go to the brake switch.
You are correct, the next plug is for a 4 pin regulator.
The plug with black and yellow/red wires look like starter solenoid wires for electric start.
The red “+” covered wire is battery positive and connects to starter solenoid.
Going up and to the right, that looks to be correctly marked as the CDI plug.
I’m perplexed by the next two wire plug. Is it “L” shaped, to plug a signal flasher into? If it’s a flat plug, I’m not sure what it goes to.
The next two wires connect to the + and - of the battery.
The last wires on the far left go to the taillight, but they look confusing. The orange and blue are typical Honda colors for turn signals. The green/yellow in the white plug is the brake light wire. Typically, the running light is solid brown, I can’t tell if any of those are brown. Solid green should be ground. I’m not sure why there is a second blue wire.
