hi i have a 2020 3500hd 4wd chassis. as is no box rear bumper just cab and frame.i added a cargo platform. installed an oem backup camera. it has 2 plugs. 1 plugged into the rear of frame junction. it has a smaller 2 wire connector. im assuming this goes to backup lite connector somewhere to activate the camera. i have no backup lites. anyone know what connector i can splice into to make it function? having a tough time finding any usable diagrams online. local dealer has been no help.
thx
