How do the Wastegate Vacuum lines Run?

[ForceFedGN]

I went to school for a year and I bought the car over that time, and it was back home with my dad, but he was going to replace the vacuum lines for the waste gate actuator but forgot how they go, I dont wanna drive the car till I get it right, anyone have any diagrams how the lines are supposed to run, or could you help me out, and info is greatly appreciated.

scroll toward the bottom of page and you'll see the picture showing the proper hookup of the wastegate Y.

On the wastegate solenoid, 5/32" hose comes from the left nipple and uses a 90 degree elbow and then 7/32" hose to a Y-connector. The y-connector is a GM piece with a special orifice in it. However, the GM replacement typically has the wrong sized orifice in it so make sure it is 0.050".

The straight part of the Y fitting goes to the compressor housing and the other part goes to the wastegate (all 7/32")
