Surprise FIND

I've had my new 2024 Ford Expedition XLT about 3 weeks. I was looking back where the jack is stored and found this new harness in a bag labeled Ford Part JL1T-15A416 and JL1T-14A348
I looked it up and found two references:
- Ford Engine Block Heater Wiring
- Ford Electrical Trailer Brake Wiring Harness

The window sticker for the vehicle shows it has this option: CLASS IV TRLR TOW PREP PAK. My Expedition came with an installed hitch receiver and a 4/7 pin trailer connector. I tested the connectors and both work (brakes lights and turn signals).

Am I correct that because the sticker indicates that my model has the "CLASS IV TRLR TOW PREP PAK", that my model comes with a hitch receiver and 4/7 pin trailer connector? And, that they threw in a free trailer brake wiring harness for a 3rd party trailer brake?

All the 4th gens come with the 4/7 pin and hitch receiver so you have it for sure.

Thanks AJ!

I'm curious if the trailer brake harness I found was a one-off occurrence or, if all vehicles come with one?

That is a good question. I ordered mine with the heavy duty tow package so I have a built in brake controller and didn't get the harness. It would be nice of Ford to include that harness for those who didn't get the built in brake controller. Being nice doesn't seem to match Ford lately LOL. Perhaps someone who didn't get the built in one can chime in if they got it too. In the end it is good for you!
