I know it's on the firewall but there are 3 vacuum lines going.

Is it the one in the middle?

Because the one on the left, I'm looking at it and it and it's connected a piece of plastic that goes nowhere.

 

It should have a plug with three wires going in to it and a vacume line going in the bottom with two screws going in the bottom up toward the hood. It says MAP on a little sticker on it. It is sort of shaped similar to an oil pan only much smaller of course.


Edit: Maybe the line goes in the top. I've held about 2000000 of them in the last week and can't remember one of the more obvious traits. Anyway... it says map on it.

 

Ok, I found it.

Also, I found that one of the vacuum lines is a dummy vacuum line. It plugs into this plastic piece that connects to nothing..
