The grid lines at the camera harness is the tiny light blue wire , it continues on to the purple wire @ the BCM and finally the BCM C-5 socket 45 orange & dk blue wire ... I'd try drying the camera with a hair dryer for about 5-7 minutes then immediately bury it in a bowl of rice with a tight lid for a day or two , reinstall . If still ghosting then replace with a new camera , or swap out your camera with a buddy's camera see if you still have ghosting or not and see If your cam ghost is his , this is a 10 min job .
Did you purchase this kit from your dealer ? If so it's probably still under warranty.
