i have a s-trim and need to know where to hook up the line so the gauge can read the boost. thanks

 

I hookd mine to a vaccuum port on the manifold on the drivers side.
Just T'd it in and ran rubber vaccuum line to the guage.

 

I ran mine to a port that went to some part of the emissions stuff. It was on the driver's side. Or you could t into any vacuum line as 2cub mentioned.

 

all my egr and AIR stuff has been removed from the car. so i guess look somewhere else for a feedline then? can't i just use the line off the bypass valve?

 

All my emissions stuff is gone too. That is why I used the port that originally was used for that.

But yes, you could tee into the hose for the bypass valve.

 

Even with the AIR and EGR removed there should still be a port on the intake manifold on the driver's side next to where the brake booster line is.

 

those hoses wont blow off? did you use hose clamps?

 

I'm only running 6 psi and my hose fits very snuggly.
I suppose you could put a small clamp on it if you're running a lot of boost just to be sure.
If it blows off you'll know right away as your guage will just say 0.
