Mystery hose

[VR4CE]

Hey guys while installing the stock air box i came across these two mystery hoses on the induction pipe,

Now firstly ill state that the car has a EBC and a defi boost gauge,

The first as you can see is a thin hose plugged up with a screw,

The second which is circled in red is fitting for a hose to fit on to, I've wrapped it up as a precaution, I searched for the mystery hose but could not find it,

I'm thinking that they might have something to do with either EBC or boost gauge, but they are definitely vacuum for something, could someone have a look on their car and report back. Thanks

the first one is where the stock boost control solenoid bleeds the air off back into the intake. (and not required if you are running a EBC)

the second is the return for the breather hose from the rear rocker cover, do you have a catch can? if not you should check if there is a loose hose/blocked off rocker cover breather.
