MBC pressure source and wastegate nipple question

[Jdiddy2k4]

I am going to be putting a joe p mbc on my car and just need to know if the nipples/connections i marked are the correct places for the vaccum hose.

Nope on both.

The bronze colored can bolted to the compressor has a nipple sticking out the right side of it in the image. That's the WGA nipple.

To the top-right of the compressor inlet (where you can see the compressor wheel and fins) is another nipple sticking out toward the camera. That's the compressor nipple.

The joe-p MBC has an in and out nipple. The in comes from the compressor nipple. The out goes to the WGA nipple.

I have no idea what that black rubber line is coming out the left of the WGA is. I know there's a vent hole on the back of the WGA...maybe someone was using that to somehow increase boost. But you don't need it (and it can't be blocked).

The hoses for the MBC should be short, but you also want to be able to reach it. I ran mine up to the top of the radiator fan shroud so that I could adjust it easily from the front of the car with the hood up. Just make sure you secure the vaccuum lines so that they don't rub/chafe against anything or get sucked into a fan somewhere.

Just look at my photo (on the bottom) in this how-to guide. It's the same turbo, as well as the same MBC, so you can't possibly screw it up. If you need more picture references, just ask. I've got 'em.
