Temp sensor question

I'm rebuilding my engine and I'm at the point where it's going back together.

It looks like I have two temp sensors in the block - one is the light style and the other is the gauge style. My dash has a temp gauge (I'm not sure if it has a light and can't check at the moment because the truck isn't here)

The manual says that one head has the temp sensor and the other is oil pressure. But I thought my oil pressure was that little line that come out the back of the block near the distributor.

Can anyone clarify this for me? If I'm supposed to have two temp sensors does it matter which one goes in which head?

Thanks,
Patrick

Oh, one other thing, what is this? It was bolted to the intake manifold.
