Trailer wiring harness/adapter? Is the truck supposed to come with it?
2015 F150 with trailer tow package
There is no adapter anywhere in the truck, I called the dealer and they said it's supposed to be in the glove box. It's not. And they are not being terribly helpful. Supposed to call me back in a bit...
If I have to buy one of these things, where would you recommend? And are they a fairly common part or unique to F150's? My 2005 just had the old style 4 pin flat trailer connector on the bumper, probably because I did not have the tow package or factory hitch.

Crazy, what "adapter" are you asking about? If you have the tow package, I believe you have an integrated brake controller and you should have both the 4-pin and 7-pin plugs at the back, and, the hitch receiver.
Supposedly, in your glove box you will have a 30 Amp trailer battery charging fuse and you may have a relay for that purpose too - I did.
But there's no other "adapter" I'm aware of for towing. The only adapter I know about is one to add a 3rd party brake controller, which you should not need.

However, in the back, you should have a connector for a 4 pin and a 7 pin, negating the need for the adapter. Have you checked that?

I have a '15 with the trailer package with the 2 covered connectors next to the license plate, but I did have a trailer adapter in my glove box. The part # on the bag is FL3T 15A416-AA, but I don't know what it's for.
It has a squarish gray connector with 4 wires about a foot long labeled as follows.
Whole wire bundle - Labeled Instrument Panel Feed Bundle
Blue wire - Labeled To Trailer Electric
Violet wire - Labeled Stop Lamp
Blue/Black wire - Ground
Blue/Violet wire - Labeled Feed from Battery
I also had a second bag FL3T 15A562-AB Rear Video Camera Wiring Protective Cap.

So, it's normally a 30A fuse, and my 2014 truck also has a relay for that purpose. The only 30A fuse whose purpose is not clear to me is #54, a "Voltage Quality Module". I'd start there, and if it's not the one, pull and check every 30A fuse. If you see anything in a "Not Used" slot, I'd pull and check that too, since the trailer battery fuse and relay are generally not installed at the factory.
Good luck. I looked in both a "first" and "third" printing of the manual, and neither one has the needed information. It really bugs me when the documentation does not keep up with the product.

This is for covering the video cable on the truck if you remove the tailgate
