I think it is the grey/pink wire on the factory harness, but not sure.

Now that I got some sleep, I'll add that I am doing a double dinn install on my turbo. When I did this on my boxster I thought I found, it but I can't remember. It appears to be on the black harness that has empty pin outs, but not sure. Any help would be appreciated. The toughest part of this install was relocating the ac module from top to bottom. I can't even begin to say how much of a pain in the a$$ that was. The factory had already done that on my boxster. The avic x950 is a lot better than the 940, but the wiring harness is a huge bundle.
