Is this needed? LS swap evap valve

[MDPotter]

See below - there is what appears to be an EVAP valve solenoid on our 2012 Gen 4 5.3 engine and there is no wiring to plug into it and there is also what looks like an outlet on that valve as well as a piece of tubing on the passenger side of the engine which has nothing connected. We bought the engine from a dismantler who took it out of a wrecked 2012 Silverado. We also had the harness reworked by Speartech (emissions and VATS removed) and we don't have any extra leads to plug into the valve. Since the emissions were removed from the computer, I'm assuming that this valve does not need to be hooked up to the computer? And how should we go about plugging or completing the loop with the open vapor tube?

This may be more of an LS1Tech forum question, but I thought maybe someone here had ran into this at some point.

Thanks in advance for any insight.
