  • Vehicle Specific

Install your Curt electric trailer brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in port beneath your 's dash.


Features:

  • Plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller
  • 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
    • Brake controller must have built-in plug for adapter to connect - will not work on controllers with pigtail wiring harnesses
  • 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.

Everything was as described. Easy easy installation in 10 minutes. Not the top of the line controller but it's all I need. Very fast shipping as well. Couldn't be more happy with etrailer. I will be purchasing my fifth through etrailer soon!

Plug and play !
Very easy install !

We purchased our new Ford Explorer with the towing package but the dealership said it didn't come with a trailer brake controller and nothing was made for our SUV so we would have to get an aftermarket controller and have them run the wiring. After looking online I found a video on etrailer.com and it was just as easy as the video to install, the hardest part was finding the Ford plug under the dash, very happy with this product and ready to haul our RV everywhere.




by:

Excellent. Perfect fit, exactly what was needed. Connected the Curt C51110 Brake control to factory wiring. Only thing that could make it better is if it came with someone to plug it in for me and save me 10 seconds.


Comments
The products worked great up until about a few weeks ago Thats when I sold the truck where the items were installed. lol. Really though, I very much liked how the products listed and purchased from etrailer.com were easy to find, fit exactly as described, and performed as needed. etrailer.com is always one of the first places I look when searching for items for my new truck.

Easy to use and customer support is awesome. First time using it I called customer support and they answered right away to make sure everything was set up correctly. 2003 Excursion

2017 Land Rover Evoque

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.




by:

Plug and play, great




by:

Nice trailer brake. Works as it should.




by:

plug-n-play, that’s what it’s supposed to do, and that’s what it does.




by:

Made the install quick and easy.




by:

Made installation a snap. Just mount the break controller, plug one end into the vehicle's factory plug and the other end into the break controller.

2004 Ford F-150

This is well worth the money. The cord ends appear to be high quality and fit the wiring connectors on the truck and brake controller perfectly. It makes hooking up your new Curt brake controller as easy as plugging in a cord. The only way to make this any easier is to have someone do it for you. The hardest part of the whole installation was finding the factory connector to plug this cord into. Hint: On my 2004 Ford F150, the brake controller connector was just above the factory diagnostic port underneath the dash.

2010 Ford Expedition

This cable made the job very easy. took 10 minutes to plug in and mount with Curt Venturer Brake Controller. Very inexpensive solution. This is an old vehicle (2001 Expedition) and didn't want to put a lot of money into a brake controller setup. These parts and directions from the website made it quick, easy and inexpensive. I have not towed with the controller yet.




by:
2000 Ford F-250 and F-350 Super Duty

I purchased this along with the Curt C51140 controller and 7 way harness to replace the mess that was spliced in on my truck when I bought it. Don't bother with splicing your controller in. Buy this harness, plug it in, don't look back. Service was great.




by:
2010 Ford Explorer

Product worked liked a charm!! I have a 2010 Ford Explorer XLT, and the Curt brake controller with the factory adapter cable was a perfect fit!

Note: Even though it doesn't specifically say on the etrailer website, the adapter connector WILL fit a 2010 Ford Explorer that has a Factory Tow package installed. The factory connector is located next to the steering column underneath the kickboard. It is kinda of hidden away, but it's up and next toe the brake pedal switch connector.

Great service and communications.

  • 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...

  • 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 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.

  • Will the Curt Custom Brake Controller Adapter # C51322 Work with a 1998 Lincoln Navigator
    The Curt Custom Wiring Adapter, # C51322, was designed to work with the factory brake controller plug on your 1998 Lincoln Navigator. The pin for the red wire coming from the brake controller should mate with the pin for the light green wire on your factory plug. It will be the middle pin and on one side you should have a pin with constant 12 volt power and the pin on the other side should have no power. I have attached a photo that shows the functions of each pin on the custom wiring adapter...

    The relay you need to activate the 12 volt power circuit of your trailer connector is available at your local Ford dealer. I wish we carried it so that you could get it from us but we do not.

This is the easiest option. The other option is to cut off the plug on the Curt brake controller # C51120 and hardwire it to the Ford harness.

  • 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.

    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.
