We used Anderson 15A power poles to have a quick disconnect for our CAN bus. A bit overkill? Sure. But they worked great and with the right crimping tool were a breeze to install. We also use the 45A on the mains. By changing the orientation of the connectors we could make it impossible to plug the wrong thing in the wrong place. We get them here:
