I was thinking about when you take it apart after a session and put it in you car. Water may then run down and into the connectors. Grease will help, but some kind of plug or lid,l could make it even better. Had loads of problems with this on diving gear that originally was supposed to be waterproof. Water inside after a session/dive is a pain.
Will look into this as well. Would be nice to just unplug everything at once. (Not in two steps).
