First thing I brought a greddy profec b 2 unit used from brian, I received the unit with no instruction on how to install it. I check the box good still nothing. The unit has all the wiring, black & red, and the other black plug into the stepper motor, it look like motor is missing the vaccum line that suppose to go to it {no big deal they} I need to know how u wire this unit? Also I am currently running a home depot mbc, which mean I had removed my oem pill's. Do i put back the oem pills inside short lines or leave them out when u installed profec b 2 type boost controller? Thanks alot for info, khris

red goes to power, black goes to ground. take out the MBC and put the stepper motor in it's place. NO NOT put back the pills

Jay thanks alot dude, Since u live closer to me than Martin then I will broow yours. let me know it's a good time to come by and pick them up. btw pm with directions on how to go to your house. Thanks Jay, Martin I will borrow Jay side markers. Also back to the boost controller on the stepping motor one nippble side a com on it? Does it really matter what side goes to the wastegate? Also which of the two short lines I install the motor on? I put 2 mbc on the pre spool and the wastegate?

hmmm if I remember correctly, you have to leave the pre-spool the way you have it, or put the pill back in. the profec b goes to the wastegate. from the turbo to the "in" port, then from the "out" port to the wategate. And also I believe on the back of the control box there is a vacuum connection. If you have a boost gauge in your car, you can get a "t" fitting. so the hose from the engine will get split. one to the boost gauge, and one to the profec

Ok can I just cap of the profec b line for the boost or does it need to be hook up? If it does hook up will it thro the parameter's of the profec b? Thanks Jay, khris

"COM" should go to the wastegate.

Ok kinda of confused now the stepper motor has 3 port, I believe one is "no" and the other is "com" that's from front to back, now on the side it has another port but it's has a plastic cap on it.
