The easiest would be to tap into the MAP switch. It's about 1.5", round, mounted to the passenger side inner fender with a vacuum line and an electrical plug plugged into it. This is what triggers the lights on the factory dash. Just "T" into the vacuum line for your boost guage.

You can also "T" into the fuel pressure regulator line, just make sure you have good fittings. You don't want the vacuum line blowing off under boost.

There is a 1/8" NPT on the front of the intake plenum behind the coilpack as well.
