Any vacuum line that's post throttle body with work. Pick one, hook a vacuum port to it, and run all your sources off the vacuum port.

I agree. I don't see him needing to tap more than 1 or 2 things into one source though. Boost controller to wastegate and turbo outlet source, BOV to PCV, then the vacuum port for boost gauge etc... to last source.

I guess you covered it in the last post. :1 Eh, it's almost midnight. Shoulda been in bed hours ago.

Brake booster line the 3/8 hose t off it or in one side of the manifold from the intake mani and out the opposite end back to the booster.Vacum manifold is the only way to go otherwise you have some gettho cluster ---- of lines everywhere.
