I built my own adapter to convert from the Furrion mount to a Tadi Brothers camera, though they now sell an adapter kit. It probably doesn't apply for the camera you've got, but here are the pix of what I came up with (sorry about the sideways view). I chose to use clear plastic so I could tell if any leaking...been on for 2 years now with many miles and many rain showers and all good. (Irrelevant to the OP, but I replaced the onboard antennae with an extended one, mounted with glue to the front of the a/c unit.)
Enjoy your 2104S!!!!!
