I have a 08 SCAB 4x4 with the reverse camera in the tailgate latch cover, nice option and Ford was smart offering this without mandatory nav like other brands. The truck came with a accessory bag with a connector labled "rear video wiring protective cap" I looked under the truck and there is already a connector!! Dealer dosent have a clue, imagine that! Only problem with this option is that you will have to crawl under truck and bust knuckles to disconnect to remove tailgate. Any body have a clue as to what I'm missing. " Part #8L3T 15A562 AA Refer to owners manual for proper use". could not find anything in the manual.

 

Answered my own question. When you remove tailgate/disconnect camera, you use this cap to seal connection.
