Usually any line that has a high vacuum at idle is good. As long as your show a vacuum at cruise that goes to zero at full throttle you probably can use the gauge as it is just a relative indicator of engine load.
The power brake line is a good source but I usually refrain from cutting into that line in the interest of brake reliability.
Look for a line that goes into the intake manifold some place rather than into the air body.
