Carrera Speedo Wiring -- Anyone know what this Br/W wire is?

[Crachian]

As far as I can tell, everything is working now that I had my speedometer repaired (broken odo gear).

Aside: I used Overseas Speedometer here in Austin and Rick Borth was great to deal with and kindly advanced the mileage according to my log records so it's still accurate.

But this Brown/White wire is a mystery. Where does it go and what does it do?

I'm also working on my speedometer at the momment. I have referenced this thread by Thrasher, there is a pic where you can see that wire (bottom right).

wait... on second thought, sorry I'm second guessing now... looks like a solid brown there.

Terminal 4 on the combined indicator light (seat belt, parking brake, brake pad wear) is a Brown/White.
