M1045A2 Just Arrived! - Need help identifying loose part

I am super exited that my 1045A2 just arrived! While doing my initial "walk-though" I discovered a loose part in the engine compartment next to the washer bottle. I would like to identify it before I attempt to get the truck running. The part appears to be a 24V buzzer of some sort with electrical connectors and what seems to be a vacuum connection. Does anyone here know what it is and/or used for? Pictures attached. Thank you!

Goes on top of the injector pump. Solenoid. Make sure your IP has one.

Awesome! Thank you for the quick reply. I'll check it out this morning. The part doesn't appear to be in great shape so if I do not have one installed i'll have to order a new one.

It’s not what the parts looks like on the outside that’s as important on the inside, AFAIC...
it appears ok, that just black paint from the rebuild. Many many of these injector pumps are now bad due to bad fuel
sitting in them for so long....
