I am returning my 2007 sti back to stock right now and removed my aftermarket 3 port boost solenoid. The problem that I am having is deciding between the two vacuum lines which goes to the "T" part by the lines near the turbo and the line going to the intake. The OEM solenoid has two lines coming off of it and I just need to know which lead goes to which source. Thanks again.

 

Port 2 goes to intake
