White/red wire in cabin...?

[Gerard]

Hi!

Someone asked me where a certain wire goes in the cabin of a 1990 Audi
100/200. I took a look in my almost stripped out cabin and found this
wire coming out from under the dashboard, then just dangling down
towards the centre console. It has a single spade connector on the end.
I haven't pulled the dash apart yet so not sure where it goes. I
couldn't find a single point for it to connect to. Only thing open was a
point on the handbrake switch.

Anyone have an idea?

Also, I attempted to make sense of the wiring diagrams in the Bentley
manuals. Perhaps I'm just clueless as usual, but I hunted for all the
red/white and white/red wires and most of them are for internal lighting
and indicate I have to follow the diagram at another track number. I
then look up the track number, but there is nothing at that point. Am I
reading this stuff correctly?

Thanks.
