Having been here without the factory tow package-
SOME of the wiring is already there.
The cab has the controller wires in the harness,
but underhood and along the frame does not.
You end up adding pins and wires to the chassis side
connector, and it's kind of a pain. If I had to do it again, I'd
avoid the factory wiring and instead add my own.
If you HAVE the tow package, adaptors are almost plug- and- stop-
I like the Tekonsha, myself, and that requires attaching it to a universal pigtail.

My truck had tow package and plug for controller, but was missing the blue wire from fire wall.
it may look like plug and play but won’t be.
i ended up getting a true variable 2008? Ford brake controller that works off a pressure sensor on the master.
really depends on how often, how far and how much towing you plan on doing.

Factory tow will have the extra relays hanging off the fuse box for the trailer brake
Look to see if that seven pin is OE or aftermarket. Tow pack had the HD cooling system, sway bars, etc.

Not if previous owner(s) have removed it.

Fair point but they would have to depin the fuse box and remove the harness down the frame to totally remove it.

My old truck had tow package, sway bars, not hd cooling, external trans cooler, single core rad, was missing the relays and wiring.
I ended up getting all wiring from a junk yard, was a pain to pull, but wanted it like factory.

Thanks everyone for replies. I do have a Tekonsha that I had used on another F150 that would have to be hardwired. Unfortunately it is in a box in storage. Storage unit is scheduled to be emptied in three weeks. Someone mentioned how much towing which would be very little and the heaviest would be a 1964 Triumph Spitfire @ 1500 lbs plus trailer.

I wouldn’t even bother, sure it helps, but your going to be under 2500lbs with that combo.
when that much weight goes in the box you don’t put extra brakes on the truck, right?

But its well in the safe range as well
If its pulled often, the brakes give the option to stabilize the trailer if it were to be sway-y, and it wears the truck brakes less
