Where does this wire go?, Broken wire - 1.7L D-jet Options

[stinkindiesel]

Car is a 1973 1.7 with original D-jet fuel injection. Wire looks to be tan or faded brown, and exits from the wiring harness under the intake plenum on the passenger side along with a green-red wire that goes to what I think is the oil pressure sensor. I've tried to capture it in the attached picture.



So, where is this wire supposed to go?

I know brown is usually ground, but I'll be darned if I can find a ground point around where this wire is. The ground point further back looks to have its full complement of wires in place.

There is a wire going to the aux air regulator already, so I don't think this is it. I thought initially it had to go to the cold start injector (?), but it would not be typical for Porsche to have put two wires into one crimp connection would it?

BTW, I hope I'm calling theses things by the right names. Sometimes it seems the more looking around I do, the more confused I get (IMG:style_emoticons/default/dry.gif)
