Where to tap in for boost gauge

[Sam95RT/TT]

Where do I tap for the boost source for my boost gauge on a TTA? Any pics or diagram would be great. Thanks

Should be a hard plastic line coming off of the smaller metal vac tube at the lower rear end of the passenger side of the intake plenum. THis is the factory vac/boost line that the factory gauge is hooked to, just tee into it somewhere near the firewall.

It will be coming off of the smaller of 2 tubes that go up to the vac block on top of the intake plenum, they are held in place by the rear passenger side intake plenum bolt.
