I have searched google but found many conflicting answers. I have a Tial wastegate, HKS bov, and a cheap ebay boost controller and I need help hooking them all up. Does anyone have a good diagram? Here are the exact ones that I have.

 

I don't have a diagram, but that set up works best if you take the T, put it in your wastegate hose with the arow toward the wastegate, then hook the painted leg of the T to the bottom arrow part of the manual controller. This way sets it up as a controlled air bleed and works pretty decent. Before you put the controller part on, blow through the bottom and get it adjusted so you can't blow air through it, then it will run off straight wastegate spring pressure, then slowly mess with the controller to raise the boost.

 

Try this,
