I just rebuilt my son's A4 B5 1.8 engine and it is running great. BUT, there is one connector I did not label and can't find a home for it. It seems to be a sensor and connects like a plug? I have a attached an image of it before I took the engine out and apart and the connector is hanging on the lower front near the drivers bumper mount. Within this image, is a closeup of the connector/sensor itself. Please help me figure out where its home is.
Thanks
Ron

 

That's the ambient air temperature sensor. The plastic bracket on the power steering cooler that sits in front of the AC condenser has a little hole in it that the ambient air temperature sensor will fit into.

 

Ahhh yes found it. I was looking for something a bit more complicated than a bracket with a hole!
Thank you
