So.....
I have an answer from cummins and an answer from Syracuse, NY | Cummins Northeast, LLC
They contradict each other.
Cummings says
"Good Afternoon Glenn,
The part that you are referring to in the pictures, looks to be a temperature sensor for coolant. I had go ask someone more more technical skills than I do. He also stated that the wiring question is kinda hard to figure out. I was advised that the sensor probably only has 1 wire, but there could be other leads that are connected to it, but that is usually done by the mechanic, not by the company. By having the leads on the sensor, it may have helped someone with the set up of the wiring so that they wouldn't have to splice somewhere else.
I hope this helps
Thank you for contacting Cummins.

Syracuse, NY | Cummins Northeast, LLC says
It is a solenoid in the air intake heater system. Judging from your photo's, it should have 2 wires connected.

One says one wire the other says two, one says temp sensor the other says solenoid.
Syracuse also sent along a diagram (attached) which describes the part as a solenoid valve, but no wiring diagram is included.
