Sensors going into intake Options

[Rider]

I just bought a short ram intake from eBay, and it seems I'm missing some things.

First of all, the stock intake has a plastic box that, as far as I can tell, is empty. It hooks in to the side of the rubber tube close to the airbox through a 1½ inch (roughly) diameter hole. The box seemed to hold the intake in place, but it's also hollow, weirdly shaped, and actually connects to the intake. The intake also had a little hole next to the manifold that had nothing connected to it.

Second, I can't find whatever sensor goes into the rubber-lined hole on the new intake right next to the filter. My brother bought an intake like this a couple years back on his old Celica, and he did have a sensor that went in there.

Third, I can't find whatever sensor hooks up to the rubber hose that comes out of the right (passenger) side of the new intake. What's it supposed to lead to?

Here are some images:
