I bought an AEM short ram for my 99 civic EX, i have it all hooked up except for the vacuum lines, which i'm worried about.

Basically, the intake has 2 holes and a nipple. I know there's a vac line that goes to the nipple, i'm also reasonably sure I have to connect the IAT sensor via a rubber grommet directly into the intake pipe itself. My question is for the remaining tube, it's a small diameter tube, not a piece of vacuum line, and it t's near the throttle body. I'm not sure what it's for.. do I cap that? What is it?

 

hm when i installed mine there was only 2 slots. one for the iat sensor plug with was like a black rubber piece and the other one was the vacuum line which you connect from the valve cover to the intake. Not sure where the other hole is there for since i have the same car lol

 

Yeah, same here?
