The 3/8 vacuum line coming off of the intake manifold at the rear. Tee into that.

do i need to break into a vac line as well or will it read both off of that one line? sorry should have asked that in my last post

It'll read both boost and vacuum.

Sorry if this is an old thread but I didn't wanna be a complete rookie and start a new thread b/c I was too lazy to research a little. Is there anyway possible that someone could possible take a picture of their boost gauge connection setup? I've tapped into every flippin hose under that hood and haven't had much luck. I've done many other boost gauges before but this one...UGH!

Thanks in advance.

At the back of the intake manifold there is a 3/8" vacuum hose running towards the driver's side. You tee into that.

Ok, I'll try that today and see what happens...
Thanks!

Ok, I tee'd into the brake booster line on the back on the intake manifold and the other 3/8" hose going to the crank case. Both gave me vacuum and boost readings but I noticed that it blows white smoke when I acclerate? Overboosting?

What's your setup? Stock? Boost spikes to? I don't have a GT to look at, but I don't remember that 3/8 hose going to the crankcase. Shouldn't be white smoke. You only tee into the brake booster hose.
