Here's a video of how I'm mounting my Slip ring connector.
This is not exactly the way I wanted it to work, But I couldn't find a better place to mount the connector. The problem this causes, The dome itself will not separate from the dome ring as easily as it has been in the past. The wiring in the dome will connect to the female connector and the male connector will run through the body as a power source. If I need to separate the dome and the dome ring, I will have to unbolt the female connector from the dome ring. This is not really a hard task, But it sure was nice to grab the dome and slide it off the ring.
I'm not sure if most builders separate the dome and ring much anyway. When I sit the dome back on the body, I will be able from the back of the body to bolt the dome to the bearing using 4 wing nuts and then connect the 2 connectors together.
