Where to plug vacuum gauge?

[FlipTrac_511]

My lil bro is an import tuner and just got some vacuum turbo gauge or something or other and he wanted to hook it up to my Trac real quick to see how good the piston rings are. Hey, it was all Greek to me too. Anyhow, where's a good vacuum line to plug this gauge into (under the hood)?

Back of the motor there are a couple... I think there is a vacuum tree there you can tap off of.. If not just use the brake booster line

Thanks Todd, and sorry I couldn't get back into chat. Anyway, I just unplugged the tube off of the brake booster to get a reading at idle only. To get a reading at WOT the gauge needs to be plugged-in in series which means I need a tee at this location; not sure if I want to go through the trouble of finding one especially since I know all is well with the Trac.
