I am surprised to learn the temp light isn't connected to anything. I have 350 engine which has 2 temp sensors. 1 temp sensor on driver side head for temp gauge, and 1 temp sensor on passenger side head for temp light. It seems odd GM would have a temp sensor for the idiot light, and not run the wire all the way to the dash light.

On a stock setup you would only have one temperature sensor. The sensor type depends on whether it is for an idiot light or gauge.
