K1200RS - Strange wiring fuel level sender

If you have an early K1200RS (1997-1998):
this is something I have never seen before and the owner says it is stock from factory.
Would appreciate feedback if you have seen this Yellow connector near the fuel level sender connector (on top of fuel tank , right side).

See attached pictures...

Early 98. Mine has it. I assumed it was user installed.

Interesting.

Re: K1200RS - Strange wiring fuel level sender

Brown wire on BMW = ground or negative
but useless.

Roland,
I was aware of the BROWN wire convention, HOWEVER having such a brown single wire connector alone, not connected to anything is strange.

This connenctor/wire does not even exist on later facelift model AND it would appear it is not even connected on early models. Well... we do not know with 100% certainty yet, but for the moment I have seen 2 members with 1997-1998 (on another forum) and 2 more members here with 1998 - all of these unconnected.

If it was intended for an optional equipment (like GPS, heated grips..) it would NOT be a single wire connector.

Re: K1200RS - Strange wiring fuel level sender

Definitely not on my 2000 manufactured 9/99. As you say, the heated grip connections are two wire and, I believe, under the tank not along the top. This is a mystery for sure. Can't wait to find out why BMW put it there....
