I have the one second from the right, but the only difference in mine and yours is that mine has female thread and yours has male threads it seems.
If you have not yet, you may find one tie wrapped near your connector. Typically there is one there from the factory for use by tow truck drivers if needed.
So far, it sounds like it may be your method of plugging in may need tweaking. It takes two hands to do it right. Hold the collar/sleeve on your coach's connector back with one hand while plugging in your adapter with the other hand.
Other suggestions to NOT start up the coach is a good idea. You do not need 125 lb air to fill up a bike tire and you should be very careful. It will probably only take a fraction of a second to fill that tire, and just a little more to blow it up.
