Mark, do you mean for the OBC tach? I retro fitted mine a couple of years ago. With Cup mirrors the sensor goes in the drivers side mirror. Parts are identified in the PET catalogue. I can dig my receipt out if you're stuck. Sensor and bracket were cheap from Porsche. I could not find the loom to tap into though despite much searching. I ended up running a new loom to the tach and scotch locking into the correct wires at the connector, which worked.

Oddly enough, George now goes by the name "Rennlistuser8", and he has been deleting many of his old posts. But here's one of his threads on the gauge install. Search for posts by username, or Project Shrek.

I installed the temp sensor when I put an OBC tach in my '90. I wanted to put the sensor in the driver side aero mirror but because these were also an update to my car the wiring harness thru the door did not have the leads for the sensor and I didn't want to mess with the wiring harness. In the end I installed the sensor on the left center behind the front grill. It works well there except when you are stopped with the AC on. In that situation the heat from the AC rad will cause a false temp reading.

Good luck!
