Can someone please post on how to hook up the EZ or EVC controller to a T78 turbo (There is No Nipple on the compressor side of the T78 like there was on my last T72 ) I think I have it hooked up right but im not 100% sure. There are three ports coming off the EZ controller, the one to the far right is small I hooked that to BOV and Intake pressure. The middle one went to the top of the wastegate and T'd into Intake vaccum (so I just T'd into the far right port already getting vaccum, The far left port went to the side of the wastgate.

On my RPS kit I belive the 2nd port went to the top of the wastegate and t'd into the compressor nipple on the turbo, but being how the T78 has no nipple on the compressor I was told just to tap it to a intake vaccum source which is what the 1st port is doing already so I just tapped that. Is this right?
