Review on 🔌 CURT 58404 Trailer Wiring Adapter for 1-1/4-Inch License Plate Light Hole - 4-Way Flat Connector, Black by John Sharma

This is an amazing little adapter. I used it to connect the trailer cable through the rear bumper to keep the cable from dangling. My previous car often had the wire dangling loose and one day it was ruined by being dragged across the floor. This problem is no longer related to the adapter. To mount this little adapter, I simply drilled through the bumper with a step drill. Do this slowly so you don't drill too big a hole. I then installed the adapter with a black silicone gasket just to make sure it stayed in place. I have a full video online of this installation (including the towbar) called "Installing a Towbar on a 2016 Subaru XV Crosstrek". It was fairly easy work and it worked well. This adapter is basic, but I highly recommend it.
