Where does this plug go, two wire green and green black.

Exactly what I was looking for! Thanks for the pics.

And now it looks like I am off to the junkyard. The solenoid is in place but the plastic hose is missing. Tahoe was stolen and I got it back. The thieves and put in a fresher engine and when it was recovered they were in the process of buttoning up the new engine. So I get to put some pieces back together that I did not take apart. I've got it running, trying to get it to the point where I can get it inspected.
