Question What connection is this?

I was plugging in my LSx 5.3 harness in today and noticed I don't have a connector to plug into this port. It looks like a vacuum port there too.

I had the harness and PCM modified by Wait4Me.

Is this plug/connection even needed?

Thanks!!

Default

IIRC from my LQ4 Manifold, thats the EVAP solenoid. It isn't needed but I think it will function even if it isn't plugged in. It just releases built up pressure in the fuel tank.
