I think the FAQ cover's this but not sure,

a hose should come off the black oil box, then you should have a splitter at the top of the manifold or close to it which branches off the same size hose and one small hose which goes directly into the manifold, the other large hose should gove over the valve cover and connect directly into the lower turbo intake hose, both garrett and mitsu turbos had the same setup like that.

If someone has changed your intake system this would explain why theres no hose there, you should consider putting things back like they should be so you dont have any future problems if your going to use it as a daily driver.
