Default Mat Sensor

I've looked in my manuals and can't find out where the MAT (Intake Air Temperture) Sensor is located. I'm pretty sure it's on the plentum, but do not know where. Can anyone give me a hand??????????
HAVE A GREAT DAY!!!!!!!!!

The MAT sensor is located under the rear of the plenum.

I don't know if GM moved it around in different years, but on the 86 it's in the center of the plenum's underside, all the way back toward the disributor.

It's kind of hard to see, but if you stand on the passenger side of the engine, look over or around the fuel pressure regulator you can just see it sticking down from the plenum. In any case you should be able to see the connections wire.
