I just recently bought a used TVVC controller but I don't know which nipple goes to the wastegate and which to Vaccum. There is an arrow on the bottom. Which direction should it flow? Also, I should have it connected to the side port of my 38mm Tial right?

 

 

the arrow indicates the flow of air/boost. so the pointed part of the arrow should be connected to the wastegate. i'm not sure on the Tial as i'm using an internal wastegate.

cool...Thanks
