Installation of Curt Brake Controller Adapter

To install your Curt electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


This adapter plugs into the port on your vehicle's built-in brake control wiring harness. The port is located in the wiring panel underneath the dash, to the left of the steering column, near the emergency brake pedal.


No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

Video Transcript for Review of CURT Trailer Brake Controller - Custom Wiring Adapter - C48RJ

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this CURT custom wiring adapter for your trailer brake controller. Now this is a custom-fit part. It is designed to fit the 2019 and newer Subaru Ascent with the factory tow package. And on a custom-fit part like this, I do like to recommend you to go to our website, use the fit guide, put in your year, model, vehicle, and it'll show you if this will work for your application. Now this is a plug-in wiring adapter that allows for a nice, quick, simple installation of your electric trailer brake controller to your vehicle.

There's no cutting or splicing required. The custom connector end right here is what it'll plug into your built-in port beneath the dash of your vehicle. And the other end right here is what it'll plug into the back of your electric brake controller. Does come with everything shown here, a couple cable ties that take up any slack in the wiring and even some installation instructions that'll describe how you connect it. Now this is compatible with time-delayed and proportional brake controllers from CURT.

Now, the brake controller itself must have the built-in plug for this adapter to connect. It does not work on controllers with the pigtail wiring harnesses. This adapter is about two feet long and it uses twelve-gauge wires with a protective covering to prevent any damage. But that's gonna do it for a look at this CURT custom wiring adapter for your trailer brake controller.

  • Availability of Custom Wiring Harness for Redarc Tow-Pro Elite Installation on 2023 Subaru Ascent
    Hey Andy! Since you have the tow package on your 2023 Subaru Ascent there is a custom wiring harness available. You will still need the Redarc Tow-Pro Elite Brake Controller # RED44FR. Then you can use the Curt Custom Wiring # C48RJ along with the Redarc Curt Adapter # 331-TPH-019. This will allow you to plug directly into the OEM brake controller port on your Ascent. If you want to save a little money, the same two wiring harnesses will also work with the Redarc Tow-Pro Liberty # RED24FR....

This kit includes the Tow-Pro Liberty RED24FR and the universal wiring harness RED69FR you referenced in your question. The Universal Mounting Panel item # 331-TPSI-001 is not included with the kit so it'll need to be purchased separately. Please note that there is no custom fit brake controller harness for your...

  • How Does Brake Controller Install in 2024 Subaru Ascent with Factory Tow Package
    Hey Doug, I did some digging and your 2024 Subaru Ascent with the factory tow package does have brake controller wiring under the dash to make installing a brake controller easier. Curt has their harness part # C48RJ which was designed for your vehicle. I really like the Redarc Tow Pro Elite part # RED44FR that you referenced and this would be an excellent option for you. To install it you would use the # C48RJ that I mentioned earlier. You would cut off the side that doesn't plug into...

  • Brake Controller for 2023 Subaru Ascent
    Hi Allen; for a brake controller on your 2023 Subaru Ascent I recommend the Redarc Tow-Pro Liberty # RED24FR. This controller is simple, reliable, and won't take up space in the cab of your vehicle. The main unit installs behind the dash so only the control knob is visible, giving it an OEM appearance. If you have a factory tow port for a brake controller you can use the Curt # C48RJ along with the Redarc adapter # 331-TPH-019 for a plug and play installation. If you do not have a 7-way...
