Can anyone shed some light on where this pipe from the top of the rear ns tgv motor should be connected?. Was loose under the inlet manifold when I removed it. Car is a bugeye wrx, any help will be much appreciated as I can't see where it should be going

 

It's a vent hose....doesn't go to anything

 

Haha well that explains why I can't find any kind of take off or connection for it....
Thanks for the help
