Vacuum sources on intake manifold

I just finished installing my greddy turbo/intercooler kits and tomorrow I'll be testing it out for the first time. My question is I wanted to know where all the vacuum lines are that I can tap into. I have the wastegate, blow off valve and boost gauge that need vacuum sources. I don't want to tap into the same line for everything like the fuel pressure regulator line but that's the only one that I know of and the only one people suggest to me.

for the boost gauge and the blow off valve the vaccum line to the stock fuel pressure regulator will be fine, just get some "T" fittings and use those. If you have the greddy kit then the turbo should have an integral waste gate that hooks up directly to the pressurized side of the compressor housing. Most wastegates need to see boost not vaccum.
