My trailer hitch was purchased at a Valley retailer and fits fine except the receiver seems to fit loosely resulting in banging noise when trailer bounces. I was finally able to purchase a universal wiring adapter at NAPA that didn't require the separate power connection. It cost $16.99 and only took about 45 minutes to install by removing the 2 tail light lenses and using scotchlocks to tap into existing wiring. Ford should be ashamed at not offering a good wiring solution when it changes it's wiring diagram. I called several Ford dealers and nobody had a solution.
