Where do vacuum lines go from boost solenoid

[ForceFedGN]

I just got my new vacuum lines with the little special Y in it and it goes to my turbo, and wastegate to my boost solenoid, but what goes on the other port of the boost solenoid. all the lines were taken off by someone else and I dont know how they go exactly. Any help would be great

The other port is just an air port -- it has a little foam filter on it stock.

Check the y-fitting to make sure the orifice is the correct size (0.050"). The GM replacements range in size. Drive the car and if you overboost, the orifice is too small. You can get replacements from John's Performance.

Make sure you have the "Y" pointed in the right direction, too. Otherwise boost will be off.
