Here is a somewhat exhaustive review of all the wires & sensors I could name for anyone who didn’t have anything as a reference.
 
I also show the wire loom that goes at the front of the oil pan and comes across to the passenger side that gets affixed to the oil pan on the passenger side.
 
The throttle body is easy, just 3 bolts and a couple of sensors (don’t forget the gasket)!  Then I attach the EVAP to the top of the intake manifold and its associated screws and sensor.

I did not button everything up because I will still be doing an oil catch can later.
