Just trying to re-install my repaired boost controller, and how it seems to have been plumbed in in Japan is different to what the instructions seem to say.

Can anyone with knowlege of how 3 port electronic boost controllers work explain how it should be, as im confused.

The side port of the wastegate is plumbed in to pre-throttle on the car, with no joins, via a stainless braided hose, so that is 100% how it was.

So that leaves me with the top port on the wastegate, and the 3 ports on the boost controller. What goes where?

According to the instructions 1 of the ports goes to the side port of the wastegate and also T'd off to pre throttle, but thats 100% NOT how it was from Japan.

Can anyone explain what goes where considering the bit that cant be changed mentioned above?
