It is the coolant temp sensor. It is the one that gives your dash a reading.

I didn’t know that, I thought it ran off the one in the intake, it had an odd connector on it, the new one I ordered for the 5.0 has a male spade connector on it and the one in the 4.3 had this odd slide over connector

Its not the knock sensor, this is on the side of the head, I’m almost thinking it’s a temp sensor
your absolutely right, its one of two. there is one also on the top of your intake manifold. one for your gauge and one for the ECU.

the one on the intake is where the ecm gets its temp reading.
