Topic: What does this wire connect to?

[HaaJeHaa]

I’m close to finishing my cafe CB750K2  build and I’m currently doing wiring. I’ve bought everything new and plugged everything where the colors match. However, one wire doesn’t make any sense (see picture), the all brown wire in placed in the headlamp. The old harness has it also, but I can’t find out what it’s used for?

The wiring diagram says all brown is from combination switch to taillight, altough there’s no wire for it to connect to, and the combination switch should be connected with the 4 prong connector. Any ideas?

 I believe it's fed from brown/white.  Is it an euro spec bike? They are a little different than the US version I'm used to.
   The passing switch may complicate things if it has that. Also the US bike has the turn signal beeper cancel button on the k2 only. The euro K2 continued on past 1972 so there may be another question.

Both the 550 and the 750 have an unused brown wire with a female terminal inside the headlight shell.

Is it a new wiring harness? When I did my 750K8 i discovered the new wiring harness colors didn't match exactly and had to spend a few days with a continuity meter, notepad and wiring diagram to get everything correct.

I guess parking light is the correct answer Thanks!

On my K3, my new harness had it. I bought a Euro headlight with the parking light, I plugged it in to that, if I remember correctly.

Yes, that's parking light from ign switch.
My Cb750 K2 has a reflector with Parking light bulb. I connected that brown wire to it.
It lit when I turn ign switch to Parking position. Rear lit too as standard.
