pipes on waste gate actuator

[hairyuk]

hi everyone. i've tried to get an answer to this question on the alternative engine forum, but no luck, so thought i'd try on here. someone must have this set up on there vans. i recentley purchased a t25 with the aaz conversion. A friend of mine looked at it the other day and noticed there's a pipe coming off the waste gate thats not connected to anything. Anyone got any ideas where this should be connected to? i've spent the last 2 evenings searching the web and have not found an answer. it's the pipe going into the top chamber of the wastegate actuator

It was an economy/emissions device that opened the wate gate under certain conditions.
Leave it disconnected.
