Thank you for your answer. i will do as you said I have a ball valve ready to use.

You are right there is a black air line going into the bottom of the auxillary air supply. I had my better half push the dump air switch as i undid one port at a time to try to detect and air release. Is this the right thing to do ?

Thank you for replying . Yes that is my question. I have dumped the air and was trying to figure out which port to use.

I have a 1998 Holiday Rambler Endeavor with an auxiliary air supply. I would like to know which port to use to connect an air hose connection to.
