No way in hell does the computer know when to emergency brake.

There have been a few times driving along the East Coast in Delaware when a gust off the ocean starts shaking my camper. A slight squeeze of the trailer brake and quick press of the accelerator puts everything back in line.

No computer will know that trick and can sense outside influences to trigger it.

Sure, I can see the computer knowing when to brake the trailer/camper, but that is only in normal slow down and stop of a light or in traffic.

Comments like above form the dealer tech are from people who have never really towed anything seriously.
That's kind of what I was getting at, I can't imagine having a brake controller without having the ability to activate the brake with a lever/button. I am not even sure how I would properly set the gain without it, I have always used the lever when setting gain. I'm no trailer brake expert though, just a casual user.

Exactly!!!

You need to set the gain WITHOUT engaging the vehicle brakes.

Proper way to set it is to find a parking lot or empty stretch of road. Get to about 20-25 mph, apply the brake controller level until the truck starts to stop by just the trailer. Too much gain and you lock up the trailer brakes. Too little gain and the trailer is pushing the vehicle and potentially overheating the brakes to a failure.

Pretty scary to hear that.

I confirmed today that you cannot adjust trailer gain from the steering wheel controls if your 2022 Expy doesn’t have the integrated TBC installed already. Called my dealership and they said they can get me in next week to install the TBC from the 21 f150. They said it should work just fine

I appreciate about your information. I ll be back dealer about that.

Could you please give some review after install TBC from dealership? Because I went my dealer, they said no wires behind the blank. I m waiting from your review after install TBC.

Thanks again.

The dash changed for the 2021 F-150.

Also, the TBC part number (Part #: JL3Z19H332AA) says it is the 2018-2023 Expedition and 2015-2020 F-150. No 2021 F-150 support. Looks like it is a different parft number.

Part #: JL3Z19H332AA is NOT fit on spot on dash. Thanks

Also, I don't believe there will be "wires" behind the dash, I think there is a harness that is needed and that harness plugs into connectors that are back there. I am not 100% on that but I believe that was what I read somewhere on here. There have been several who have done this.
I haven't paid a lot of attention to the 2022's but with the dash change on them it is possible the trailer brake controller is different but I could see it being the same as on a different model.

It should be one big plug that clips into the back. Whether that plugs is tied up in the dash someplacve, not sure. I don't think there should be any wiring or slicing that needs to occur.

I don't really feel like ripping apart my dash to track where the wires from the TBC go.

I have confirmed that my expedition doesn’t have the wire harness on the back of the coin tray like it should either. I spoke with the parts guy and he’s trying to figure out what they can do. He said according to the schematics he has on his end, the pigtail should be there. Maybe something the production line skipped or messed up on??
