2007 XC70 breather refresh. Most parts are out but confused on where the other end of this goes. The one not under in intake? Its part #30731068. Complete system PCV main hose. Would post a picture if I knew how.

Goes to the PTC or air and head for coolant.

Some unsolicited advice:

Be careful with that coolant banjo on the head, some aftermarket kits have the fitting on in the wrong direction and it will spit coolant everywhere. With the two washers it should not leak, if it does do not keep tightening it!! You will strip it and have a not so fun time. 20ftlbs is sufficient.
