I have a new-to-me 2018 Cyclone 4005 and I just winterized it for the first time. I think I got everything squared away, except this quick connect water line that is located on the street side of my unit towards the rear of the coach. I also have a quick connect connection in my water station. The connection in the water station has hand controls for hot and cold. The quick connect at the rear of the coach doesn't to have anything.
I'd like to run antifreeze through this line, but I don't know how to control it.
Thanks for any tips, Tom
