which hose to hook into?

i need to stick a manual boost gauge on my alltrac to see just how much boost the damn thing is gettin in teh mornings when its cold, infact all teh time.. pegs the dash gauge to the wood at about 3/4 throttle all the way up to 7k..

i know on old 80's turbo subarus i just tied in to the intake manifold with a t-fitting a long piece of vacuum line and my guage..

not sure where to hook into on this alltrac...

on the back of the intake manifold there should be a port that is capped off, remove the cap and attach your vac. line. Thats where I have my installed.

easy enough, thanks a bunch..
