  • 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. For most applications, this harness is located beneath the dash, near the center console.


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.

Made installation in a Land Rover Discovery Sport a breeze! Note: This option isn’t listed on either Curt or eTrailer, but it is absolutely an option if you have the factory installed OEM trailer tow package. Your factory tow package must be dealer activated in your vehicle’s software to use the quick connect harness shown here. Total plug and play. Zero cutting, splicing or tapping required! Fantastic. TIP: Select your model year and Land Rover Evoque (Shares the same chassis and tow electrics as the Discovery Sport) if you want the right part numbers for your quick connect options. 794750

Ask the Experts about this Curt Accessories and Parts

  • Where is Install Connector on 2014 Ford Explorer for Curt Brake Controller
    The correct install harness for a Curt brake controller in a 2014 Ford Explorer is the part # C51322. The harness you are looking for on your vehicle will be under the dash to the center towards the center console. I attached an install video that shows a different brand controller and harness installed in a 2013 Ford Explorer which will be the exact same process. Around the 10 minute mark is where the connector on the vehicle is found.

  • Brake Controller Installed on 2001 Ford Van Causes Turn Signal to Malfunction
    You are using the factory pigtail provided when you purchased the vehicle, not the # C51322, is that correct? If this is the case, the factory pigtail uses a different wire color code than the aftermarket ones, which match up color for color. Before proceeding further, lets make sure you have the pigtail wired correctly to the brake controller. An incorrectly wired harness or pigtail could cause the problem you describe. Over the years, Ford has made two different factory pigtails, one...

  • Will Brake Controller Plug-In Adapter C51322 Fit 2004 Ford Expedition And 2004 Ford E-350
    The Curt Custom Wiring Adapter, part # C51322 is designed to work with the # C51110 brake controller and will fit both of your vehicles if there is a factory trailer connector installed on the vehicle. If you have a 4-way connector on either vehicle then you will also need part # 37185. If your E-350 does not have a trailer connector you will first need to install a 4-way connector like part # 18252. You will then need part # ETBC7 to get a 7-way at the back of your vehicle. If...

  • Parts Needed to Install a Brake Controller in a 1994 Ford Bronco

  • Does Curt Brake Controller Install Harness # C51322 Fit 2007 Ford F-150
    The Curt brake controller install harness part # C51322 that you referenced is a confirmed fit for your 2007 Ford F-150.This adapter plugs into the port on your vehicle's built-in brake control wiring harness. For most applications, this harness is located beneath the dash, near the center console. Most likely the mechanic you brought it to didn't know where to connect it. This would work well with the proportional Triflex part # C51140.

  • Economically Priced Proportional Brake Controller Recommendation for a 2004 Ford F-150
    For a great brake controller at a great price I would recommend the Curt Triflex Brake Controller part # C51140. This is a proportional brake controller that will sense how much braking power the tow vehicle is applying and will proportionately apply the trailer brakes to slow the trailer down in a smooth, effective manner. To install the brake controller all you need is the correct install harness which would be the part # C51322. Check out the link to the install video I attached as well.

  • Recommended Curt Wiring Harness for Brake Controller on 2003 Ford Explorer

For your 2003 Ford Explorer Eddie Bauer edition, that wiring adapter is the Curt Custom Wiring Adapter for Trailer Brake Controllers # C51322. On an Explorer that harness is behind the glove box on the passenger's side.

  • Brake Controller Wiring Harness for a Curt Brake Controller on a 2014 Ram 1500
    If you are using a Curt trailer brake controller then for your 2014 Ram 1500 you will need harness # C51453. Harness # C51322 fits Ford, Land Rover, Lincoln, and Mercury vehicles. The new Rams have a unique multiplex wiring system called Powernet. Because of this new design it requires a special brake controller harness, # C51453, which will allow the Curt brake controller to function properly.

    To install the Curt TriFlex # C51140 trailer brake controller in your 2006 GMC Savana Van you will need to wire in harness part # C51515. Vehicles with the 7-way tow package have the blue output brake wire already run from the back to the front. It is located under the dash near the emergency brake pedal. This connects to the blue wire on the harness. The white wire connects to battery negative, the red wire connects to the cold side of the brake light switch and the black wire connects...

  • Recommended Brake Controller for a 2018 Thor Ace Motorhome
    For your 2018 Thor Ace Motorhome, I recommend using the Curt Spectrum Trailer Brake Controller part # C51170. The reason for this is because this unit is composed of two main parts, the control box and the output knob. The control box gets mounted out of site and then the output knob will get installed up on your dash for easy use and a very aesthetically pleasing look. The color output of the knob also helps with ease of use. Since your motorhome is on a Ford F-53 chassis, you can use...

    Thank you for purchasing your Curt Tri-Flex trailer brake controller # C51140 and matching wiring adapter # C51322 for your 2009 Lincoln Navigator. I am sorry you are having an issue with the trailer braking power being weak. If your voltage readings are taken on the trailer at the brake assemblies, and you are reading 12V there, then chances are that the issue is on the trailer side. The pad tension, which is set with the star wheel adjuster, should be set so that with the trailer jacked...
