    [PUT] First of all, I just want to say that we have been towing our trailer for the past 15 years. But, when we purchased a lovely used 2011 Ford F-150 EcoBoost truck with built in tow package, we ran into a problem, our refrigerator was set for running on battery when we were traveling to and from the campground and the new TV did not charge the battery or provide power to the refrigerator to keep it cold [:(]. This is our first experience with having this happen. I've read that manufacturers will sometimes not fully wire the receiver. Is this true? When I take it in to the dealer [MOD] what questions should I be asking them? I want to be prepared so that I make sure they rectify the problem. Experts what do you think?

    Probably needs a fuse is all, they don't always install the power fuse when building.

    Relay or fuse. It may be in the truck somewhere with other wires in a bag. Read your owners manual.

    Probably just need a relay. I just added one to my '02 F150 with the factory tow package for the same reason.

    Check Relay number 9 in the box under the hood. My guess is the spot is empty. You just need to pick up the appropriate relay either from a dealer or auto parts store.

    Also check fuses 21 and 54 in the same box as they also mention the trailer charge circuit.

    These are all from the owners manual. http://www.fordservicecontent.com/Ford_Content/catalog/owner_guides/11f12og3e.pdf

    My brother-in-law had the same problem with his Ford. We checked it out while on a camping trip together and found that Ford was to cheep to put the relay and fuse in for the charging line to the 7 pin factory tow package plug. What good is having the 7 pin plug if they don't do it all?

    They're in the glove box when bought new. Most of the time they get tossed by the detail guy if bought used.
