One with wires is the temp sensor for the ECM.
One with vaccum lines is a temp sensor for the emissions AIR pump system.

The one is for the ECM; however, the other is the thermal vacuum switch for the EFE (heat riser) system. You can see how it hooks up on this diagram; it's called "EFE TVS".

my bad. I knew that one of the lines were common with the AIR system. But I guess that was the common source vac.
I will try to do better in the future.
