I have a 2017 Leaf S. My rear camera stops working. Instead of replacing it, I decided to install a 360 view system that has camera on each side of the car. I have installed the camera at the bottom of the passenger side rear view mirror. I was able to pull the wire from mirror to door. I am trying to bring the wire into cabin through the door wire boot. I can remove it on the door side. But the connector on the cabin side seems to be more than just a robber gasket. Has anybody had experience removing it? Any suggestion about how to remove it will be greatly appreciated.
