Quick and easy, get a vacuum line T and splice into it behind the instrument cluster.

Ah.....I better read the post before answering... sorry :roll:
No, without a guage there now your better off running a hose from the engine compartment all the way to your gauge.

if you remove the false bulk head there is a moulded white pipe going through to the inside of the car next to the heater pipes there is also a cut out in the false bulk head to get the pipe to the engine there you can t in to the pipe to you dump valve then from inside the car remove the top of the dash and the white pipe can be seen to the left of the heater ducts from there to the boost gauge

i just ran a boosty gauge on my '91 2.3 t. i spliced into teh vacuum line coming out of the intake manifold, ran the tube from the cabin side. On my car, there was a real nice rubber stop with two wire bundles coming thru up and to the left of the brake pedal. shove a straight/stiff wire through first, so you can find it on the other side of the firewall in teh engine compartment.

from there... run said wire down from where you're mounting the gauge to the footwell. and from the wire, you can tape your tube to it and pull it through :) once again, a project that took 7 hours to plan, strategize, scratch one's head, kick various car components, and curse; and about 20 minutes to pull off.
