Hi Mark; have you tried looking behind the center dash storage pocket? Technically on the vehicle the location is BH7. It will be similar to the attached picture on an Expedition. You can also take a look at the installation video I attached further down on this page for the Redarc Tow-Pro Liberty # RED67CR. Brad covers where the factory wiring port is located on a 2022 F-250 so I would start there.

Mark, I was able to make a plastic cover that went in the space where the oem brake controller was located and just plug my redarc wire harness in for my 2019 F 150. Wasn't that bad to do. I'd show you a picture, but I am not able to upload one to the reply for some reason.
