What's going on guys? I just wanted to make sure I hooked up my EBC correctly. In the diagram, it shows a 3-way vaccum line connecting from the Intake Manifold, then to the fuel pressure regulator and back to the controller. Is this correct? If anyone had a picture of some sort, I'd appreciate it. For some reason I just dont think it should go that way. Thanks in advance.

Its an internal wastegate. I've got it hooked up to the wastegate correctly, but I'm a little unsure of the 3-way vaccum line that connects to the actual unit inside of the car.

Yes there is a black box. I've got all of that hooked up correctly. But like I said before, the unit inside has a vaccum port that calls for 3-way connection somewhere to the intake manifold. That's what I'm unsure about...

i thought you were talking about the sylonoid under the hood,sorry.you can install the tee in the vacume line to the regulator then it goes to the back of the actual unit.

Oh ok. So I did have it hooked up correctly. It does connect to the vaccum line connecting to the fuel pressure regulator and the intake manifold....

Holy crap with the people not getting it.

The Profec B spec 2 has a port on the back of the unit itself for its internal boost gauge. This is what he wants to hook up.

MO87NA: You don't need to hook it up to the one running to the fuel pressure regulator. You can tee into ANY vacuum line coming off the intake manifold. Pick one closest to the firewall, and connect into it :)

Thanks for the help Rob. It's not a Spec 2, it's just the regular Profec B. I guess that shouldn't make a difference though.
