I’m trying to add the factory trailer brake controller to my 22. Apparently in the changes to the 22 I have the old style connector and the dash mounting position of the new controller. Has anyone been successful sourcing an adapter of some sort? The vehicle has the hd tow package, just not the gain adjustment controller.

What was the solution to this? I'm getting ready to do the same thing

I'm working on trying to do this too, along with adding the Pro Trailer Backup Assist. The last piece I ordered for it is supposed to arrive tomorrow. If I'm successful with what I'm trying to do, I'll report back with details. *Fingers Crossed*
How could HD tow package not come with a trailer brake controller? That doesn't make any sense to me.

Here's where I currently stand:
I've purchased the following parts:
I'd love to get this figured out on my vehicle and get it all documented for others to be able to follow too. I'm really surprised at how hard this has been to figure out and have run across many others who are also struggling with it. I'm mainly trying to get the trailer brake controller figured out first and will then focus on the Pro Trailer backup feature after that.
I've purchased the following parts:
- Trailer Brake Switch: ML3Z-14529-AC
- Jumper Wire: NL1Z14A411F
- Trailer Brake Module (With Pro Trailer): ML3Z19H332J
- Pro Trailer Knob: ML3Z19H540AA
- Dash Panel to support pro trailer knob install: NL1Z7804339CA

Update: I have the hardware physically installed, but couldn't get the software programmed to work. We bit the bullet and brought it to a dealer and their service team said the FDRS software said it couldn't be setup on this make/model. We then took it to another dealer that has an "Accessory Department". They didn't have success either, but want to order some replacement parts to see if that will make a difference. We're expecting they will have those in and take another look at it next week...
I’m not sure it’s possible. Seeing the 22 and 24s appear to have the same harness at connector 238 on the main harness side the wires needed are not in the connector. I just tried wiring my own wires and with Fords FDRS software I can not enable it. Possibly you could with Forscan but as a dealer tech I don’t currently have Forscan to try. If I get this one on this 24 to work I will update this.

I'd really appreciate an update once you have one! The last dealer we had it at, ordered some other parts suspecting there was something wrong with mine, but they didn't work either and they ultimately cited that the FDRS software said that adding the brake controller is not available on this make and model year. I'm not accepting that this is truly the case. Maybe it doesn't make financial sense, but it has to be possible because there are vehicles that were originally sold with this option in this model year... So it just has to be a matter of what modules need to be ordered/installed. Right??
