Default TT Boost Read / vacuum host

TT is electrical but.. tapping in for boost is more of an engine thing.. but this is for an electrical device afterall.. so my question is where is the vacuum located. i see a tube consist of 2 tubes, connected by a two way conjuntion and then its connected to another tube with a three way conjunction. i'm not sure if that is the tube to pull apart and for me to insert the three way conjunction provided by blitz.. any remarks?

For a boost gauge or other measuring device you need to tap a direct manifold connection. The easiest one to use is the vacuum line to the factory bypass valve on the intercooler. That is where the optional Subaru boost gauge gets connected, as well as most aftermarket ones.

Let me know if you need any help hey1. I'd be willing to guide ya thru it. But yah like Mulder says the location is correct to tap the boost gauge and you run the line to the rubber grommet thru the firewall.
