Where is the IAT sensor

I have a 1989 firebird formula 350 and I need to know where the IAT sensor is located. Pictures would help but any info is greatly appreciated

It is under the intake plennum on the back side. I dont have any pictures that would be useful really, but if you look under the plennum right in front of the distributor it should be there. Youll be able to feel the plug and sensor with your hand if you feel around under there. It is the same style sensor as a coolant temp. sensor. Good luck.
