I should have paid closer attention to matt99199's cable ends. They need to extend like his is shown. I had to use a heat gun and warm up the PLA plastic sleeve and push the connector past the flush point to get it to make connection. While it was hot and pliable, I pushed it into the camera port to get a molded and snug fit. I also modified the swivel mount to recess the 3M tape 1mm to allow a flush mounting (no holes drilled in the camper). I attached the stl files for the swivel mount and some zip tie mounts if anyone wants them. They accept the 3M 13mm tape.
