EJ22T: Where to tap for Boost gauge -and- What is the 2nd cylinder for?

Here's a shot of my BPV. I know on my WRX I threw a 'T' on the hose that ran between the BPV and the manifold. Does the same go for here? I'm thinking the top hose that has the little piece of white tape sticking to it.





2nd question: There is a 2nd cylinder resembling the brake master cylinder sitting under my IC. Is that the clutch master cylinder?

 

you are correct on both...same hose and yes clutch cylinder then slave underneath that

 

you can tap pretty much any vacuum line fore the boost gauge. (except the EGR line)

 

Excellent. Off to get a 'T' fitting and find a hole in the firewall.

 

I ran my boost gauge line through the fender and through the side of the firewall, there should be a big bundle of wires that go through by the driver's side door hinge

 

The legacy has a hole just underneath the brake master cylinder, just to the right of the clutch pedal from the inside. There should be a grommet you can put a small hole in and feed the line through.

 

Thanks. After I get back from North Dakota I'll finish this up.
