What kind of audio system do you have? That main console display "tells the Tale" being that when you start the car, that console "boots" with a displayed wording like
"Ford Audio System" - then it uses one kind of connector harness to the Radio head unit and...
...if it does not show that...
It would mean FORD logo appears - then that means the connector is separate with its own harness to a SYNC unit under the Glove-box
So it may help explain the types of Y-Tube vids you see are not equal to your situation.
Can you post a pic of what your console "Boots" as? We may be able to help or at least give others hope for a solution.
However, due to the changes - the older "Ford Audio System" may be harder to find than the more modernized FORD colored logo display one. - Due to one was used more extensively in the UK while USA was modded to the newer more current display.
