vacuum control tube

[montzz32gtr]

hi , ive done some work to my r32 gtr including taking off recurc pipes and im not 100% sure to where the vacuum control tube went to , if it was the recurc tubes where should i put it now ?

its 1 of the vacuum tubes that comes round the back of the engine ,
1 is actually a metal water supply . (i know this as ive had turbos off too)
1 splits into 2 and goes to turbo actuators .(this on mine isnt needed any more as ive put profec b boost cont on it so ive blocked it off)
the other i know is the vacuum control tube as r32 gtr manual shows it ,but where should i put it as ive no recurc pipes now (if thats where it did go)
regards steve
