This is kinda different that other boost controllers. The tech still doesn't say to cap off any of the TB intake vacuum connections, of which the Z32 wiki does. Apparently one of the connections are capped while the other side connects to the NO port and the hoses that were connected to it are T'd to the COM. Finally the electrical wiring is routed to the balance tube port. Geesh, I honestly think I could explain it a lot better...especially if I had pictures.
