Heres a link on how to set up your vacuum lines.

Those two wires are not both grounds. One goes to the switch. It goes like this:
(the dashes are the wires)

[12v source]---------[switch]----------[mbc]--------[ground]

So when the switch is on, the power goes to the mbc, activating the secondary controller. Flip the switch off and it goes back the the first boost setting. There should be only 2 vacuum tube nipples, one from the turbo, and one to the waste gate. And I think those screws are just meant for mounting purposes.

I'm having the hardest time setting up my dual stage MBC. I contacted Dejon, but their answer was not really clear. I have it hooked up and wired. No matter which way I switch the solenoid, I hit 20psi (even with the MBC backed way out). I obviously have something hooked up wrong. I have the green circle connected to the boost source. The red circle is connected to the wastegate. I have open dump and it's not opening at all. The solenoid is working because I can hear/feel it switch. I'm clueless.. Any help would be greatly appreciated!
