wiring harness junction box under throttle body

I have a 2007 328i N51 engine. I pulled the intake manifold and the wiring harness junction box under the throttle body. Now I'm putting it back together and have a plug left over and can't figure out where it goes. It's a short cable so has to be close but I don't see anything it could plug into. In this link you can see the plug: https://photos.app.*******/zuHz75FRXXKr5FRj8
The wiring harness is part # 7555016 but I couldn't find a wiring diagram for it. Hoping someone can tell me what I'm missing here.

Some more info on this. Problem is, I can't get the engine started. When I try to start the engine it cranks over and sounds like it can't get enough fuel. It will labor and then start for a second and then quit. Giving it gas with the gas pedal doesn't help. Only code it's throwing is 2D5A (Monitoring engine torque limiting) which I don't think is much and 2D0F Air mass sensor. I did disconnect the mass air flow sensor but have it connected to the air box now.
