It is not uncommon for certain factory brake controllers to have issues with electric over hydraulic brakes. This would be the first we have heard of this issue with a 2023 Ford F-350, but it is possible that the brake controller in your ford is simply not compatible with electric over hydraulic brakes. There may be an adapter module available depending on what brand of actuator you have on your trailer so that is one option. If you can tell me the make and model of your actuator I can see if we have a compatible adapter.

With some of the newer controllers, the manufacturer can actually send software updates to the controller. So it may be worth checking with Ford to see if an update is required in order to operate EOH brakes.

Another potential option is to replace the factory controller with an aftermarket controller. Most any aftermarket brake controller like the Tekonsha Prodigy P3 # 90195 or Redarc Tow Pro Liberty # RED24FR will be compatible with EOH brakes. So making this switch is basically guaranteed to resolve the issue and allow your trailer brakes to work normally. With the Redarc controller you have the option for a plug-and-play install using the # 331-TPH-007 wiring harness. Generally, this is the approach I recommend.

Answer 1

You are correct, this is actually a fairly common occurrence and a known issue for the newer Ford trucks and their factory TBC not working with Dexter EOH brakes. Ford did have a recall for almost 400,000 trucks with this issue and they discovered…

Since your factory Ford brake controller has a hydraulic mode setting you would not need to use any type of adapter like the part #DX35FR that you referenced.

The "Trailer Disconnected" error message on the dash with a factory brake controller is usually related to an issue with the blue brake output wire that runs from the brake controller to the 7-Way connector. The fact that the issue remains…

Yes, you can use the HydraStar Electric Over Hydraulic Actuator Adapter Module #HBA-CAM with the Dexter DX Series Electric Over Hydraulic Disc Brake Actuator #K71-651. In my experience I find the Hydrastar HBA-CAM is the most reliable module with the…

Answer 6

It sounds like there is a short somewhere in your trailer wiring that is causing the #K71-651 to run. Unless the actuator itself has an internal problem the only way it is going to activate is if it senses that a truck is connected. The black wire of…

Answer 7

This is exact same adapter as the Dexter part number you mentioned with the part #DX35FR. Now with that said your 2022 Ford F-250 shouldn't need this adapter so that makes me think you just need to put your brake controller into hydraulic mode.

Answer 8

The pump should come on when you hit the brakes with your Dexter EOH system. I hope you have the Dexter #K71-651 for disc brakes versus the #K71-650 you asked from which will not work with disc brakes because it won't provide enough pressure. If…

If you are needing the hub and drum assembly then you will want to go with the Dexter Trailer Hub and Drum Assembly #8-201-5UC3-EZ but if you are just looking for an idler hub then you will want part #8-213-5UC1 instead. These come with the correct…

The manual lockout on your Atwood 85778 surge brake coupler is there so that you can back up the trailer without the brakes locking up on you. Yes you can safely tow your trailer with the broken manual lockout, you just have to make sure you…

I checked with Curt and they do show the Curt Trailer Hitch Receiver part #C13233 as a fit for a 2022 Volvo XC90 All Models which includes the Recharge.

From what I could find it looks like your 122R (red) and 122Y (amber) lights measure 3.75" x 1.70" x .81". We don't have any replacement lense directly for the GLO-BRITE lights but we do have some similar lights that you could use…
