  • No cutting or splicing required
    • Custom connector end plugs into the built-in port beneath the dash of your vehicle
    • Other end plugs into the back of your electric brake controller
  • Compatible with time-delayed and proportional brake controllers from Curt

  • 2' Long, 12-gauge wires have protective covering to deter damage
  • Limited 1-year warranty


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 harness is located underneath the dash, to the left of the steering column, and it is taped to another harness 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.

  • Is Curt Spectrum Trailer Brake Controller A Good Option For 2020 Chevy Silverado 1500
    The Curt Spectrum Trailer Brake Controller part # C51170 and the custom wiring adapter part # C51525 is a great option for the 2020 Chevy Silverado 1500 because of its simple out of the way installation. The knob can be installed in any easy to reach location at any orientation. The main unit installs out of the way and utilizes the custom adapter plug for your truck to plug into the factory port. I have attached the measurements of both the main unit and the knob for you to get an idea...

  • Curt Spectrum Trailer Brake Controller and Charge Line Circuits On a 2022 Chevy Silverado 1500 LTD
    The Curt Spectrum Trailer Brake Controller # C51170 will not charge the breakaway battery on your 2022 Chevrolet Silverado 1500 LTD. The charge line portion of the 7-way trailer connector runs on a separate terminal(see image). The charge line will be located in the 1 o'clock position while power from the brake controller is sent through the terminal in the 5 o'clock position. If you are not getting 12 volt power to this terminal you will want to check the fuses on your Silverado. The...

  • Parts Needed to Install Curt C49UR Assure Brake Controller on 2021 Chevy Silverado
    To install the # C49UR Curt Assure brake controller in a 2021 Chevy Silverado, in addition to the controller you'll also need a # C51525 brake controller wiring harness. The harness plugs in to the connector located under the dash just left of the steering column next to the e-brake pedal as shown in the provided photo. I've linked to a demonstration video showing how the brake controller works.

  • What Brake Controller Do You Recommend For My 2022 GMC Yukon XL AT4
    I prefer brake controllers that have proportional braking. Your trailer gets the same braking power that you are applying in your tow vehicle. With that in mind, my recommended brake controller is the Curt Spectrum Trailer Brake Controller - 1 to 4 Axles - Proportional - Dash Mount, part # C51170. You will also need the Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In, part # C51525. This controller can be installed in your cab in any orientation and it plugs into...

  • How Would Brake Controller Install in 2021 Chevy Tahoe
    If that part is available it would be through GM only. But you could also bypass needing a connector and just wire what you have found directly to a brake controller like the Brake EVN part # TK63VR instead. For this controller the black wire is the 12 volt power wire, red is stoplight circuit, blue is brake output, and white is ground.

  • Can Redarc Tow Pro Elite Brake Controller Install in 2021 Yukon XL Denali
    The Redarc Tow Pro Elite brake controller part # RED44FR can install in your 2021 GMC Yukon XL but you'll need to use the correct brake controller install harness which is part # C51525. You'd have to cut the black connector off of the harness and wire it by color to the harness of the Redarc and you'd be set. This is one of the nicest controllers out there as it uses an inertia sensor to determine how much brake pressure to apply and only installs a small knob on the dash.

  • Recommended Trailer Brake Controller for a 2022 Chevy Silverado 1500 RST

  • Where Is Factory Trailer Brake Controller Port On 2021 Chevrolet Tahoe W/ Factory Tow Package?
    The factory trailer brake controller port on your 2021 Chevrolet Tahoe is located underneath the dash just to the left of the steering wheel. It will be taped to another harness so it may take a bit of looking to find. Keep in mind that if your Tahoe does not have the factory tow package, the connector may not be there and you would need to hardwire a controller. At this time (5/30/2021) the only plug-in adapter confirmed to fit is the Curt Custom Wiring Adapter for Trailer Brake Controllers...

  • How Does Curt Assure Brake Controller Install in 2022 Chevy Tahoe
    To install the Curt Assure brake controller part # C49UR in your 2022 Chevy Tahoe would only require the install harness part # C51525 which plugs right in under the dash. The Assure is Curt's answer to the P3 part # 90195 as it has a full screen that uses full words instead of codes to decipher that is also proportional.

  • Where is the Factory Trailer Brake Controller Port On a 2022 Chevrolet Tahoe
    If your 2022 Chevrolet Tahoe does not have the factory tow package then the plug may not be there. If this is the case you would need to hardwire in a brake controller. If your Tahoe does have the tow package then the plug will be under the dash. The plug will often times be taped together with another harness making it not always apparent that it is the plug you are looking for. You may need to do some searching to find the correct plug. Currently at this time (2/10/2022) the only adapter...

  • Troubleshooting Curt Spectrum Brake Controller # C51170 in a 2021 Chevrolet Silverado 2500HD
    We have not yet been able to install a Brake Controller # C51170 on a 2021 Chevrolet Silverado 2500. The thing that I do not like to hear is when you replaced the controller your issues changed. I would begin by checking the Curt Custom Wiring Adapter # C51525 for the ensure that it is receiving the correct power from your Silverado. You can use a Test Light # PTW2992 or Multimeter # PT29ZR to test the adapter wiring. With the ignition on you should have constant 12 volt power to the...
