The plug and play connector is only available from Ford. I went that route on my van. On my dad's van, I went with the e-trailer universal 7-way. Both work fine. The Ford plug and cover are more durable, but the universal one is cheap to replace when it breaks. And the connectors that come with the universal option are not waterproof.
Note: The F-series connectors are not the same as the E-series connectors.
Kinda funny how I was on here 6 months ago asking almost the same thing and I get nothing but crickets,,,,,,, Trailer place wants $450 dollars to do almost the same thing + add a electric brakes device.
