Did you order a 402a or ? There's been a lot of confusion about the tow packages, what is different, what you get, are the tow ratings different, etc. Most could not get confident about what was different hardware-wise between the tow tech and the trailer tow.
On my 401a, when I ordered (12/1/21), I can tell you that the 360 degree camera package was NOT a part of the Trailer Tow package ($1090) but was a part of the Tow Tech package ($880). I opted for the tow tech package because I really wanted the 360 degree cameras. I was told if I wanted the trailer tow package AND the 360 degree cameras, I would have to add the cameras to the Trailer Tow turning it into about a $1800 deal. No one could tell me what 'more' I was getting by going that route.
Anyways...I think this is Ford finally correcting the issue and tells me that maybe the Trailer Tow package just adds the tailgate LED and some additional wiring maybe. The 7-pin connector is standard I believe across all trim levels (seems I saw some documentation about that).
