I do not know the name for this part but there is a black box on the side of the engine that has individual harnesses going to sensors such as thermostat housing temperature. I am looking for a diagram for that.

Hello, I am Danny,

Is there a chance you can take a picture with your phone and upload it here? I have attached a picture of what I found. The thermostat outlet sensor wire goes to the DCE (Digital Motor Electronics Control unit). I have circled in red. Hope this helps and thanks for using 2CarPros.

Hello again.

Can you take another picture from a little farther away? It is kind of hard to see. Hope this helps and thanks for using 2CarPros.
