I installed the 15$ Harbor Freight clearance lights on my 2019 f250 a few years ago (because every Super Duty should have them). Back then I tied them to an upfitter switch because I did not want to reach down into the dashboard to connect them to the stock parking light connector (if the 250 even has one). I just found this gizmo on Starkeys website and it was really easy to install. I just connected the + from the clearance lights to the wire labeled “parking” and it works like the lights were OEM. They Fedexed the package to me which was appreciated. I got home from work at 5:45, changed, did the full install, tested it and was on time for dinner at 6:30.
