Default Where is the MAT sensor located?

I can't find the MAT sensor on my 85. From my understanding it is supposed to be under the rear of the intake manifold just unfront of the distributor. However the sensor that I see there only has one wire and according to the shop manual it is supposed to have two. Right now I seem to get code 23 MAT voltage high intermittently.

It is located in the bottom rear of the plenum and has a two wire plug. The only one wire sensor on the intake manifold is the EGR temp sensor.
