I have 3 cameras that the connector failed and came off of the cable. Here is a link with some additional info
I'm going to call shopchevyparts.com tomorrow. This is a design issue, there needs to be a stress relief that connects the cable(s) to the bumper connector. This may be less of an issue for a bumper pull, but a 5th wheel or goose neck connection using just the camera connectors is doomed to fail.
