Recently purchased a used 2014 2500 SLT. It came with a Tommy Gate installed on the back. With this the bumper and camera were removed. I would like to install a new camera to the existing wiring if possible (looking for tips on how to possibly do so). Also the Park assist sensors were disconnected and now I keep getting a message on my dash saying it isn't working. Is there a way to get rid of these messages or attach new sensors so the message would go away?
