Run a length of hose from the valley cover outlet to the catch-can inlet, then CC outlet to intake (side) inlet. For the fresh air inlet get a pcv breather(remove the pcv valve) that will fit into the oil fill on the passengerside valve cover.

That's how I did mine.

BTW, the RevXtreme CC has a built-in pcv, at least mine does.

It's nothing like a typical mini air filter breather, it drawls metered air through the TB.
