#27679, "RE: Anyone ever installed the Blitz SBC-ID?" In response to In response to 4
The SBC has a control module located inside the car and there is a vacuum line connected to that. I teed off from my boost gauge line to the control module.
I have a Tial wastegate, so I do have 2 ports on it, so that is not a problem. I guess I am going to try to install it like the diagram shows and see what happens.
