The title pretty much says it all, but I was poking around trying to solve another issue when I came across what appeared to a a disconnected connection. The bike appears to run fine without it, and the wires don't easily reach each other, so maybe there's a missing device between the two?

One thing I thought it possibly might be, is something to do with my temperature light on the gauges, as it doesn't light up on startup, but I've read somewhere that's normal.

The picture is taken right up at the steerer tube, left hand side.

Thanks for any ideas as to what it might be

You say your bike is a K100 or is it a RS or RT or a naked straight K100.
Many of us have put the bike model and year in the signature line, it helps us old farts with dementure to remember which it is Laughing.
There are several unused connectors on a harness so it may well be for some accessory you don't have. The picture didn't come through but I presume the temp gauge is a MotoMeter brand and so OEM, these have a flat 4 pin plug.
It is normal for the lights to go off when starting.  There is a load shedding relay that disconnects all unneeded electricals when you press the start button.

This could be the connection to the horn.
What's the colour on the wires?
Which model and year is your bike?

That pic is not showing on my computer.
There're a few connections under the tank for optional accessories including security system etc so its probably something like that.
Number of pins and wire colours and we could soon find what that is.
Cheers

Whoopsie..... Might have kind of forgotten to host the photo...Embarassed

The wires on the label side are black with yellow stripe (Might be green stripe, I'm colour blind) And yellow with black stripe. The non labeled end are both the same colour. Probably yellow.

Pretty sure it's an RS. It doesn't have a stock fairing on it, and the insurance says straight up K100, but in doing a search on the VIN, I seem to recall it telling me it was supposed to be an rs. When I figure out how to do it, I'll add a picture of it to my profile.

It stand "KUPPL"...=....kupplung....=....clutch switch.

Looks like the time is right for rerouting the wire from the switch......
first check that the function is OK.

The function this switch have is that you can start the bike when in gear.....
if you pull the clutch.

Why I first did guess horn.....in german it's "HUPE"......and that the letters could
be difficult to read.........

Aha! Thanks for the translation! I've noticed a few of the safety "features" have been disabled on this bike...

That's it Inge. Now I see the connector its from the clutch lever switch.
A while back I was tidying the wires thru the steering head and when I turned the steering to the right the clutch sw wires tensioned and the connector separated. Took a while to work out what was happening.
Rusty, you just need to try to pull it thru to get a bit more wire into the under tank area. Sometimes wires can be wound around or tangled. If not you'll need to extend it.

Cheers

Go here realoem.com and type in the last seven digits of your VIN in the appropriate place...
