Wiring Harness

[keges335]

I am working on a 1981 Honda CB 750 K. I plugged all the wiring plugs together in the Headlight bucket. And Turnsignal plugs etc.
I have a Blk Female and a Brown female plug left over. And no wires left to plug into these 2 Any suggestions ?

Thks Keith.

I just put a new harness in my 81 cb750c. The original harness had a black, brown and one or 2 green not plugged into anything so i just left them as so on the new harness.
I assume they just use one harness for multiple bikes and leave the unneeded wires in place to simplify manufacturing. My turn signal flasher for example has only 2 prongs but 3 wires going to it so one is left dangling. Apparently different models/years had turn signal flashers with either 2 or 3 prongs but the harness was left the same.

I’m having the same issue, replaced my wiring harness and have some leftover wires. The original harness had some black wires with different colored bands on them. Are those grounds? Pic is my leftover wires.

One black female plug and one brown female plug is totally normal in my 1980 CB750K; they're on the wiring diagram as going nowhere. It's an additional power connection inside the headlight that's switched to the ignition from what I remember. Meant for accessories and such.

Check your wiring diagram.
