Well guys I decided to make up a quick chart on how to run the hoses from the stock boost control solenoid to your car. I came across this issue when returning my 3-port ebcs back to the stock boost control solenoid. The plumbing wasn't really the issue, for me it was finding the hoses to order from Subaru that go there. Along with this diagram I made up, I also put the corresponding part numbers for the hoses. Hopefully someone in the future will find this information useful, as I really could have used it. It took me hours or studying the diagrams online to find the correct parts. Hope this helps someone else!!!

Forgot to put the part number for the "T" section. Subaru part #14447AA320 (Hose assembly/turbo) That part number will bring up the "T", and both hoses.

The restrictor pill for the 09-14 WRX's is 1.2mm. Part # 22326KA120

Made a couple updates here. With the vf52 turbo on the 09-14 wrx's, the "T" section actually has 2 restrictor pills. They are marked like so: one hose has a yellow mark, it will go to the right when looking at the turbo, to the turbo compressor; the other hose is marked with a pink/purple mark, it will go left, to the wastegate.
