Salutaations:
Heartbreaking isn't it? Still, exceptionally good news that everything else is correct.
Personally, I would disconnect as it will not harm your engine to be disconnected until you can get the BPC working. You can seal up the loom connector with a little non-latex silicon chalking if you intend to run without the BPC connected for any length of time. Don't force it in, just make a plug cover.
It could be that either your air circuit channel is blocked with something or that your control disk has lodged in a groove it cuts in the vent ring.
You might want to *very gently* poke around with a pipe cleaner through #1 and #3 nipple to see if it draws any crud. Even more gently, poke just inside #2 nipple - if you are seeing brass dust on the pipe cleaner from #2 (W) nipple - your BPC control disk is likely starting to eat the vent ring.
If you are seeing a lot of brass dust from your swipe inside #2 nipple - then you should be aware that introducing any air or cleaning fluid may in finally fact break up the internal wires or push some brass filings into bad places - but this will be because the wires are too far gone or the vent ring is worn through badly and both ready to go soon.
Soo - perform the next steps with warnings.
First try clearing the air circuit with some hits from a compressed air can (Staples around here) - it has a nice thin tube which should be placed as deeply as possible into the top (#1) nipple and then bottom (#3) nipple.
Do the top one first, then the bottom one - then try to flush anything it clears from the centre nipple (#2 - W).
DO NOT push the air can tube very deeply into the centre nipple as there are wires towards the loom connector side that can be very easily damaged. If you hit something solid with the air can tube on #2 nipple - you have gone too far, back it out 1/4 inch. Do not block the back flow when you flush #2 nipple.
If it is still is not operable - then move to contact cleaner (brake/carb cleaner are not good choices) and again be careful when shooting into the centre (W) nipple. Repeat process as above with warnings as noted about middle (W) nipple. Then, again, flush with compressed air can.
If it still doesn't work - then I would strongly suspect a jammed control disk internally and you can sometimes free it by *gently* tapping the BPC on it's side on a bench with the loom connector facing up (it will have jammed in that side of the vent ring).
Finally - perform the same cleaning proceedure on the compessor outlet and air intake connections on the engine. Also blow out the lines between the BPC and the engine while they are off. Long shot, but worth doing just in case.
If it works after being tapped on the table - then flush one more time with contact cleaner and air at #1 and #3 nipples *only* and then pay close attention to how it works in the coming months. If it jams up again, know that it is coming close to shorting the wires and needs to be replaced at some point in the foreseeable future.
If all that fails - then you are in fact boned and might want to look at some choices for MBC+A devices (Jeff in Atl has a good one I think). Sorry for your pain brother - that's why I'm working on a fix when I have time.
