I need a picture of the spot under the rear license plate.

A strange request, I know. I have been having issues with corrosion in the rear tailgate. First the camera and now the rear taillights. I washed the truck yesterday and while drying the rear hatch I realized it is full of water. Water just kept running out of every opening (i.e. the latch). I went looking around for a place the water could get in. I noticed that under the license plate is a hole with no grommet or anything to cover it. Does anyone else have this hole with nothing covering it?

Anyone else getting water in the taillights?

Thanks
Marc
