I tried quickly  to pull the plug off, but there is the metal ring that I could not get off with my fingers. The car was also hot, so it wasn't great conditions to try. Will try again this week end.

But I do not believe it will make a difference.  I also pulled the ' wrong plug' and it does open the flaps ( bout no better sound then with PSE on ) ...  So I do not see what that other plug can do different ?
