Where do those hoses go?

Here's hIGGI's engine.



I went to the junkyard the other day and I saw that there's a hose attaching this thingy and going to the back of the engine.
So I wondered which way does the hose has to be positioned? It's a special hose that only let air go through one way.
And where does it attach to in the back of the engine? There's 2 holes, but I can't remember which one it is.

Thanks!

IT goes tot he beige thermo valve on the back of the TB, toward the top. IT'll have a cap over the end, and 2 nipples ont eh bottom, IT can go to either nipple, and the other nipple has a line that leads to a metal nipple about 6" farther down ont eh back of the intake manifold. Its some of that cold start idle thermo bullshit, it changes the way the car reacts as it warms up.

It also sticks, and prevents the throttle plates from opening fully, and thus preventing anyone from going WOT, ever!

Time for a TB mod!!!
