Help with sensor identification...

L98, In front of the intake manifold. I believe the one with the "blue" arrow is the coolant temperature sensor that reports to the ECM. I have no idea what the one with the green arrow is.

Thanks!

The other pointed to by the green arrow is the cold start temperature switch which powers the cold start injector the fuse for that circuit is called the "Crank Fuse" - not exactly intuitive is it?

Thanks for the reply. Well the Stealth Ram does not have a place for a cold start injector. So I take it I just leave that connector there and won't use it?
