You're the man! so when you have your finger on the red tab just move it back like half an inch and you will feel some plastic that's flimsy and when you press down it will bend then you just pull and disconnect. It doesn't really feel like its meant to be pressed which is why it took me an hour just to figure out how to disconnect the damn thing.So I’ve figured out that if you put the ignition in accessory mode and hit the exhaust button, the valve opens 100% and stays there until the car times out and goes back to sleep.

But for the life of me, I can’t figure out how to disconnect the electrical connector! There’s the red tab on top that is easy enough to push in or pull out. Where’s the other tab to disengage the connector?
