need help hooking up profec B to deltagate

[fugitive]

i have a greddy profec b spec 2 boost controller im trying to hook up. can someone tell me where the vacuum hoses hook from the greddy solenoid. so far i have i have one hose running from the in car controller to the port on the side of the deltagate labeled boost

1)one hose is from the in car controller to a fitting labeled boost on the side of the deltagate

2)another hose running from the fiiting on the turbo to the NC port on the greddy solenoid

3)now if i hook up a hose to the COM port on the solenoid where does this run to?? i have one fitting that is currently plugged on the deltagate that is labeled vacuum. do i replace the plug with a fitting for the hose? or do i have the hose running from in car controller hooked up wrong?

thanks
