Senors on lower half of thermostat housing

[turbotsi92]

Just curious as to what the 2 sensors are the go into the lower half of the thermostat housing on a 92. I was also trying to find the pics that break down everything in the engine bay, but i can't remember where they are.

I thought that picture would tell what they were, but it doesn't. Does anyone know?

One is a coolant temp sensor, the other a vacuum port that switches based on coolant temp.
