2011 EB no power to 7 pin trailer connector

So i have searched and found nothing. Am I missing something. I can not get power at my 7 pin with the key on. Blinkers and everything else works. When I had my gmc there was a fuse you had to install. Is this the case with the F 150? If so where is it please.

F-150's have traditionally been shipped with two parts in the glove box to install for full 7-pin trailer connectivity, as you determined. Does this still apply to 2011?

You may find a bag with a fuse and a relay in your truck when you take delivery. Mine was in the drivers door map pocket, but it may be in the glovebox. The bag was marked with the part number AL3T-15A416-AA. These provide power to the trailer battery charge pin located on the 7-pin trailer plug. Install the relay into position 9 of the underhood fuse box located on top of the radiator. Install the fuse into position 21. The circuit has a capacity of 30A.

If you have a backup camera, you may find another plug in the glove box. This plug is used to cap the camera wiring connector in case you remove the tailgate.

This is for a 2011, FWIW. On my 2001 there were several fuses and relays included in the bag with the brake controller pigtail. These fuses and relays powered the trailer battery charge circuit, the electric trailer brake battery feed circuit and the reverse light circuit. These went in the underhood fuse box located on the drivers side fenderwell.

There was no fuse in the bag in the glove box. Just a relay. Bag was open.
