I was told that the truck had to have the software on the truck for the camera to work the top plug must be to separate plugs that says left and right they open up separately the 7 pin is on the bottom. Had mine at the dealership to have it install on my enclosed trailer and they couldn’t do it been waiting for a while to see if the software is on the truck they said you can’t just change the plug.If anyone find out please let me know it was one of the reason I brought the truck
