Where is the cylinder head temperature sensing unit located in my truck?

I do dozens of these a year. You will need to remove the intake to get to the chewed up connector and sensor because it sits in the valley. Be sure to clean up the mouse nest real good and it would be a good idea to inspect the intake for cracks along the seal areas and replace the crossover pipe o-ring while you are there. Not a difficult repair, just time consuming. Here is the sensor location in the diagrams below.
