That steel box protects the wiring. The intention is to remove that box when you install Ford's Trailer Tow Kit that's available
here on Ford Accessories. Part of the installation step for that kit requires you to remove the rear bumper.
I don't know if you are using Ford's kit or an aftermarket kit... but more likely than not you'll have to remove the rear bumper to complete the installation.
