Maybe, I should have posted "Female" before outlet. Sorry for the confusion.
I got both, one innie and one outie.
The (Male) innie is going where the old input was and the (Female) outie is going curbside. The outie comes close to fitting the old water tank inlet hole and will give me 120V power on that side of the trailer. The water change over is another story.
The matching Male inlet is part # HBL61CM64 and there is one Buy it now
