Please identify this cable…

Hi all. Got this small cable with no home on my 12J ‘87 110 rebuild.
The wires are black with a white trace.
There’s a pair of mating connectors coming through the bulkhead spare, and one of the cables goes to pin 6 on one of the co sole multi-connectors.
Black/white in the diagrams I’ve found seem to indicate brake warning but I see no connectors on the master cylinder.
So, any ideas? Pleeeeease.

Have you not got a pressure differential valve on the lower bulkhead into which four brake line pipes enter and a pressure switch

Black/white comes from the brake fluid reservoir cap float to the lower connector in your hand - sometimes new reservoir caps are bought without electrical connections and so are not reconnected.

Not sure of the other single pic connector, my 87 Ninety does not have this type - hopefully someone will have one on their OneTen/110.

Plus 1 on the above.

I know sod all about the 110 but that plug looks like and older version of a standard connector, I had similar on a trickle charger on my old bike.
IMO it's not factory fit.

Hi. Not that I can see.

Is it possible that at some time there was a level sensing cap on the brake fluid reservoir that the more modern connector went to, but this has now gone and the cable is redundant?
Seems to make sense.
