p0447 code on 08 Forester

Looking for some answers for this fault. I am getting the usual CEL and flashing Cruise light on the instrument panel. The code reader reports this as P0447 code VENT CONT CCT OPEN. There are two solenoid valves is the system. Which valve is this code referring to: the drain valve embedded in the canister or the pressure control valve mounted separately? To me, the name implies the pressure control valve which I have checked. It seems to engage when wired directly to the battery, although it seems a bit sluggish.
When I checked the drain control valve, one of the wires broke off right at the connector. It was holding on by a few strands and wishful thinking. It broke off completely when I disconnected the cable from the canister. If the P0447 code is referring to this valve then I have found the fault. Which brings me to the other problem. There is nothing left to splice to. Anyone know where I can find a replacement connector complete with attached pins and wire? I checked the local auto wreckers ... nothing available.
