Official summary
Some 2017-2019 F-Super Duty vehicles equipped with the factory 5th-wheel gooseneck hitch prep package may require replacement of the pickup bed. The 2020 F-Super Duty pickup beds have superseded the 2017-2019 F-Super Duty pickup bed and the existing rear bed plug/connector housing is not interchangeable with the new style pickup bed. To correct the condition, order and install wiring harness LC3Z-13A576-H, which contains the new style connector housing.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
