Props to OP for having the courage ask a question that many would call dumb. You don’t know what you don’t know and the only way to learn is to ask.
Well done!
Pry off the cap in the middle. Hose screws into there. The spinning part helps you attach hose. If you don’t already have a 90 degree adapter, you will want one. Takes weight off hose.
Might want to replace it. Supposed to look like this:
JR Products (160-85-A-3P-A Black City Water Flange https://www.amazon.com/dp/B00KNB6EUG/ref=cm_sw_r_cp_api_glt_fabc_30PJ1JK13R1F37P9VP5R
You got set up. There’s a tab that connects it to the RV when it’s open it would have been obvious if it was there.
Yea that part in the middle comes out. I think I spent a half hour trying to figure it out my first time. I was about to get some tools out. It seems so obvious now but the first time it sure was confusing for me too.
