My father in law just purchased a 2012 F150 XLT 5.0. It did not come with the factory towing package, but since we have a small dual axle trailer here, he would like to add a hitch and brake controller to the truck. We need to add a 7-pin plug and a brake controller inside the cab, so I was wondering what is the best way to add this to a truck that never had a towing package?

Is there a harness at the back that we can hook up to a 7-pin plug?

On a few of my older F150s they had a plug under the dash that you could plug an aftermarket brake controller into. Would his truck still have this plug even though it never had the towing package?

 

I don't know about the 2012's but my 08 came with the trailer package but no brake control. I bought a brake control and it just plugged in under the dash. Another truck I had didn't have a trailer packaged but had a plug under the rear bumper to plug a 7 pin plug in.

There's a little bit of conflicting information about this, but here's the best info i have been able to find:

the plug under the dash should still be there, but the fuses and relays in the power distrobution box probably aren't.

The wires for the 7-way plug should at least be run all the way to the back axle, but may extend all the way back (not sure). you should , at the very least, have the 4-way connector on the rear bumper, most (if not all) do.

My expedition has the factory 4-way plug, and the electric brake wire run all the way to the back, but the rest of the wires that make up the 7-way plug terminate at the rear axle, i would expect yours to be similar.

if you are very lucky, you will find a big round connector under the rear bumper that looks something like this:

if that's the case, you should be able to buy the plug above, mount it, and install the proper fuses and relays in the fuse box and you are golden .... but i wouldn't hold high hopes in that being the case.

sorry for not being able to be more specific than that. maybe someone who has done it will chime in.

 

I purchased a Ford Controller and a harness that goes from the rear axle area to the hitch. This harness has the 7 pin receiver. If you want a hitch, that will accept the 7 pin receiver, you must buy the Ford hitch. or make your own mount for the 7 pin receiver.
I also found that the Blue wire that usually goes from a harness plug ( beginning on the left inner fender)to the 7 pin was not in the harness.
We had to run a new wire. Fuse and relay comes with the Controller.
I am sorry, but I have misplaced the part numbers. I have a 2012 XL.

Do a search, because someone posted the whole process for installing the Ford controller.
