Did you get this fixed?
Having the exact problems with my 2017 F450 PU, we tried the "fix" with the module and it was $90 wasted. I tried hooking the trailer to the wife's F150 Raptor and it works fine. The pin weight alone would crush the Raptor but it could at least apply the brakes. Dexter says it will work but they are telling falsehoods, their actuators are NOT compatible with the new Fords even with their magic gismo. I had an emergency trip to get the trailer unloaded and I was at over 30K gross with no trailer brakes. Towhaul, manual exhaust braking, avoiding hills allowed me to limp it to get the trailer offloaded. Good thing F450's have huge brakes!

Ford sent an “engineer” out several times. They tore my truck apart, checked the trailer numerous times. They checked all outputs from the truck. They had spent the better part of the day with my truck in pieces. I don’t know what keyed the thought. The trailer had been checked by them, a trailer dealer each on several occasions. The 2008 wasn’t to picky about brake wiring polarity, the 2017 is. They swapped the white and blue wires and it works as intended. I’m guessing over 25 man hours was spent on this simple problem.

Actually where they switched them they might not be white and blue, they told me they were reversed and I remembered the stupid $100 module that didn’t work went between white and blue. They did not change the truck, they swapped wires on the trailer, everyone walked away, myself included, feeling STUPID! The crazy part is, we tried in an aftermarket controller while waiting for a fix and it worked great with the truck wiring and the trailers. The Factory unit is picky, it monitors everything constantly.
