Sorry it seemed that valve only had two outputs.
But since it´s 3 outputs then you can use it like the webshop one.
You don´t need to put pressure on top of the wastegate.
The reason to so that is when you are running alot higher above the spring pressure and you need to have pressure on the valve to keep it from opening because of exhaust manifold pressure.
So if that´s what your doing then connect from manifold to bottom of wastegate.
And connect from manifold to valve to top of wastegate, so when you bleed pressure from that line the springs effective pressure is chanced.
