Yeah, that's the egr, I saw that in the diagram, lol.

I asked what that is, because that's next to the air pressure sensor, and I didnt know what the air pressure sensor was either... and the air pressure sensor was connected to the thing I was trying to figure out by my air box... but yeah mystery solved, lol.

Thanks everyone

...and yeah I like Vailskier's set up, Im gunna go off that I think.
