I have the left front wheel well apart to replace the outside temp sensor (was missing) and found a few strange things (isn't that how it always works?)

First, I found a pair of yellow wires, soldered together via a resistor. Was this an attempt to "repair" the absent outside temp sensor? Are these the wires that go to the temp sensor?

Next, in the rear of the wheel well, I found 2 unused wires with female spade tip ends on them. One is black with a white stripe, the other brown. They come out of a shrink wrapped wiring harness (some of the other wires go to the tempostat). Anyone have a clue on these 2 wires? I saw that Viribus had a thread on this in July, but no final conclusion...

Thanks!

Not seeing it for sure, its a guess...but, my guess is those are the sender wires.

odds are the wires BEHIND the wheel well are for the "euro" side markers. In order to keep costs down a bit, Im sure porsche kept the wiring harnesses pretty similar for all the 928s

Thanks, Tony - that makes sense about the rear wires.

I checked voltages and resistance across the yellow wires after removing the resistor - it does change significantly when I put on the climate control on. So that kind of confirms these are the correct wires (I think).

Any more thoughts?

Tony is correct on both questions.

Thanks, Tony and Earl.
I checked with DR at 928 Specialists and he concurred as well.
Looking forward to real climate control (I hope!)
