@Muvybuf How did you get the cabling to the inner hole? My 2018 has a bulk head between the outer and inner hole.I mounted the same square plastic connection that brossman shows in the location that Geo shows. I put a white version of the square plastic plug under the van in the existing square hole. It was very tedious to get it to fit and held tight.
The problem is now when there is ice and snow on the van any melting seems to run right to that socket. The plug occasionally freezes and I need to take a heat gun and warm it up before I can disconnect. While I like the hidden nature of the plug location, I think some of the inconveniences of having it below might outweigh the conveniences and the visible nature of having it on the bumper.
