Outside Temp sensor

[Kevin Kingan]

 Hi all;
Does anyone know where the outside temp sensor is located on a B4 Audi?
There is a nice 90 that has the outside temp option in the junkyard(sorry
Salvage yard) near me and I would like to get it for my 90. I have the
speedo guage and need the other part( temp sendor and harness) any help
would greatly be appreciated!!
Thanks all
Kevin
