Boost gauge help please

[szalajka05]

So I just bought my first gauge for my pilar. Autometer sport comp 2 black face 30/20 boost gauge. Question is, where do I T it off at so I have boost and vacuum. Pictures please

Theres the line from the watergate that has a T under the snout and continues behind the engine, do I T it again before or after the the T that is already there?

The line the comes out of the lower intake manifold. Tee it after the tee
