I recently purchased the GM accessory.camera, part number 8494****. I installed it on my trailer and 2021.silverado 3500 HD i turned pulling the coax apart at the connector that plugs into the bumper of the truck. I have been unable to find the repair connector. This is a $400 camera accessory and i don't want to buy the complete camera when I need just a replacement connector. Please provide the source of the coax cable or where i can order the repair of the camera. Barry Stombaugh Stombaughbl@***.com
