its too cold and wet to go outside and look but from memory,
vacume pipe from the ................................................

couldnt remeber so i went and had a look..

vacume line from the the inlet manifold to the side of the w/g
vacume line from the exit of the turbo in to boost controller solanoid and from there to the top of the w/g.

I am sure that if you are not using a solanoid (elec boost contoller) of any kind, and boost is to be set at the spring setting, then its the other way round, ie   inlet to the top and turbo/charge pipe to the side.  The idea being that the boost is stronger at the charge pipe than it is at the engine so the boost from the turbo pushes the piston up/open, the top vacume pipe just puts a slightly lower boost above the piston to keep it closed and stop it opening to quickly,   thats how i think it works, but the first bit i know is right as i have a GReddy profec B which controls boost perfectly.

Good luck, hope it helps.......   i\'m cold now and my socks are wet

:(
