    • Custom connector end plugs into the built-in port behind the dash of your vehicle
    • Other end plugs into the back of your electric brake controller

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 behind the dash.


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.

Kate M. my salesperson, had a most professional interaction with me being certain of my and my vehicle's needs. In addition, she walked me through the complete installation process. This I completed, wiring the 7-way and the Curt Discovery Controller making no errors along the way. On the first test, every terminal on the 7-way tested as it should. When we came home with the RV from the dealer, all the lights and the brakes worked flawlessly. Many thanks!!

Adapted Curt brake controller for my 2014 Ford F150 STX without any problems. Just find your Ford brake control connector behind the coin slot on the left side of the dash and plug it in.

The Curt wiring adapter for my 2009 Ford F-150 plugged into the controller and the truck connector under the dashboard exactly as it should have. It works great.



by:
2010 Ford F-150

The cable assembly made installation quick and easy, all I had to do was locate the Ford supplied connector in my F150. The cable assembly supplied by Curt plugs into the Ford provided connector. Plug the opposite end of the Curt supplied cable into the controller and the electrical installation is complete. Note: the Ford supplied connector has a protective cover on it, you have to remove this cover before this Curt connector will plug in.

Installing and using the Curt trailer brake controller was simple and worked perfectly. I Can say the same about the customer service at etrailer. And will certainly be using them both

I purchased the C51436 adapter to install the C51130 trailer brake controller in my 2010 Ford pickup. Everything worked as stated. Good products from a good company with quick service.

I am very happy with all of my purchases from etrailer. The products are still working fine after a year and your company is very good to work with. Any future needs I have will be purchased at etrailer.

2013 Ford F-150

Etrailer provided outstanding information regarding the technical details of the product along with easy to understand installation instructions. The brake controller provided a cost effective solution for my basic requirements. The installation was a "snap", the only time consuming task was determining the optimal location/position install the brake controller. Item was installed in a 2013 Ford F150 and I use it on a dual axle trailer for hauling a compact Kubota tractor.



by:
2012 Ford F-150

Excellent - no hesitation in making that evaluation

I bought a brake controller, interface cable for the F150, and the 7 pin plug that goes on the back bumper. All items are great quality. Parts arrived as expected with shipping as paid for. I am installing the equipment, but don't have any issues. There were no installation instructions, however these are available on line line detail. I do not expect any operational probems but am a few days from making that test.

2016 Ford F-150

This pigtail that Dan T. with e-trailer help me get order an shipped worked perfectly. It was a custom fit for 2016 F-150 w/ no tow pkg and a Curt 51120 brake controller. This will almost complete my conversion of my truck that had no tow pkg. In the end it will help my daughter tow her Shooting S barrel horse safely to the shows. Thank you Dan T.

Made install easy. I ran my own 12 ga wire to 7 pin connector for trailer brakes. I couldnt find the fuse and or relay needed for my 2011 F150 to complete factory circuit. I NEEDED the trailer the next day with a 3,000 lb tractor on it. Worked well.

2009 Ford F-150

Researched, purchased and installed a hitch and brake controller for my 2009 F-150. It was so much easier using etrailer. I have recommended them to several friends for their towing needs.

Exactly what I needed. It worked great and arrived in 3 days right before an 1600 mile trip. It plugged right into my trailer brake harness and was easy to install. Took me less than a minute.

  • Should Curt Spectrum Brake Controller Show Lights on Display When Connected to Truck
    With a trailer disconnected the Curt Spectrum part # C51170 that you referenced should have the outer two lights flashing blue at idle or solid blue when the brakes are on. Since you used the correct install harness for this controller in your 2010 Ford F-150, part # C51436 you most likely have a blown fuse under the hood of the truck for the brake controller circuit. That would be only thing that would kill the circuits that power the controller.

  • Does Redarc Tow-Pro Brake Controller Have a Custom Adapter to Fit a 2023 Ford F-150
    Technically no, since Redarc doesn't make a lot of custom adapter plugs, but we have the parts you can use to make one for the Redarc Tow-Pro Elite # RED44FR or the Liberty # RED52VR! Curt has their Custom Wiring Adapter # C51436 listed out to fit your 2023 Ford F-150 with the factory tow package so all you'll need to do is cut off the black connector and then splice the pigtail that comes with your Redarc controller to the Curt adapter (by matching the colors) and you'll be good to go.

  • Installing a 7-Way and Trailer Brake Controller on a 2011 Ford F-150 with Factory 4-Way
    In order to determine if you will need any additional wiring you will want to look under the truck and find where the factory 4-Way harness plugs into another harness forward of the rear of the truck. If you find this harness you will see that where it is plugged in the forward harness has more wires going into it than the harness that leads to the 4-Way. If you peel back the protective covering on the forward harness there should be additional wires. Use a circuit tester like # 3808 to...

  • Installation of Curt Venturer Brake Controller # C74VV in 2011 Ford F-150
    Your 2011 Ford F-150 has a quick-connect port under the dash to allow for convenient plug-in installation of a trailer brake controller. The harness part you referenced, part # C51436, provides this connection instead of forcing you to hard-wire the unit. Your harness may be pinned out incorrectly for your 2011 F-150. Please refer to the linked article which explains the correct pin assignments for the harness you have. It may just be necessary for you to relocate the ground and brake...

  • Parts Needed to Install Curt TriFlex NEXT Brake Controller on a 2018 Ford F-150
    To install the Curt TriFlex NEXT Trailer Brake Controller # C24VV to your 2018 Ford F-150 I recommend also picking up the Custom Wiring Adapter # C51436 so the installation is a plug and play setup. You'll be able to find the OEM connector on your Ford behind the center console controls (see attached instructions). If your F-150 came from the factory with a 7-Way connector at the back then you're good to go, otherwise if it came with the 4-Way then you also need the Universal Installation...

  • Trailer Brake Controller Recommendation for 2022 Ford F-150
    Since you have more than one trailer I would recommend the Curt Echo Under Dash Brake Controller part # C27JR as it has ability to save different trailer profiles so you can more easily go between trailers without having to completely set up the brake controller. This an under dash controller that once installed just needs to sync to your smartphone and is ready to tow with. The correct install harness for this and your 2022 Ford F-150 would be the # C51436 and you'd be set.

  • Brake Controller Recommendation and Install for a 2014 Ford F-150
    If you have a factory 7-way connector at the rear of your 2014 Ford F-150 I would recommend the Curt Brake Controller part # C24VV and the install harness part # C51436. These two parts will make installation very easy as the harness plugs into the controller and then the other end plugs into the port under your dash. If you have a factory 4-way connection at the rear of your vehicle you will also need the part # 37185 to complete the install. Check out the FAQ article to the right for...

  • Harness to Install Prodigy P3 In 2020 Ford F-150
    The Ford brake controller install harness part # 22292 is currently unavailable due to an extended back order so what you could use is the Curt # C51436 to install the P3 part # 90195 but you would need to cut off the black connector and hardwire it to the wires of the P3 color by color.

  • Can a P2 Trailer Brake Controller from a 1998 Ford F-150 Be Used in a Rental 2012 Ford F-150
    The 1998 Ford F-150 and 2012 F-150 do not use the same wiring harness (a 2012 would use # 22292). Because you would have to put holes in the dash of the truck to mount the controller, it is probably not something the rental place will let you do. But if they allow you to or can find a factory screw to mount the controller mounting bracket to then it could work. A 2nd option is to use a time delay brake controller because they do not have to be mounted any certain way and you can just set...

  • Parts Needed to Install Curt Venturer Brake Controller in 2018 Ford F-150 with 7-Way
    To install the Curt Venturer brake controller part # C74VV all you need is the install harness part # C51436 that you referenced. This plugs into the port on your controller under the dash and then into the connector of the Venturer. You would not need to flash the computer of the truck either.

  • Curt Brake Controller Adapter For 2019 Ford Expedition
    I am happy to help you install the Curt Triflex part # C24VV in your 2019 Ford Expedition with a factory 7-way. I recommend to use Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51436 to install the brake controller. It will plug into a built-in port under the dash of the Ford and the other end plugs into the brake controller to power the brake output circuit on the 7-way to tow a trailer with brakes.

  • Where Does Wiring Harness for Curt Venturer Connect to in Cab of 2016 Ford F-150
    The Curt Venturer Brake Controller # C74VV installs with the wiring harness # C51436 behind a panel in your 2016 Ford F-150's dash counsel. The panel you will need to remove in just to the right on the steering wheel. See the video I've attached and skip ahead to about the 2:30 mark to see the panel. From their the video will show you the rest of the install.

  • Troubleshooting Curt TriFlex Brake Controller Keeping Motorhome from Turning On
    If your motorhome has the 2015 Ford F-450 cab and chassis that you input for your vehicle info then the Wiring Adapter # C51436 is the problem. You should actually be using the Wiring Adapter # C51432 for your TriFlex # C24VV instead. When I spoke with my contact at Curt he said that for the Ford pickups if the wrong adapter is used then it does something to the anti-theft and keeps the vehicle from starting.

  • Troubleshooting Curt Triflex Brake Controller that Wont Power On Installed on 2018 Ford F-150
    The install harness part # C51436 is the correct harness to install the Curt Triflex part # C24VV in your 2018 Ford F-150. What I would do is verify the controller wiring has power on the black wire as this is the power circuit for it. You'd want to use a circuit tester like part # PTW2993 for this. If there is no power there then check under the hood for a blown fuse for the brake controller power circuit. If there is power there then you most likely have a bad brake controller as with...

  • Can 2017 Ford F-150 With 7-Way Have Trailer Brake Controller Installed
    So, I'm going to go ahead and rip the Band-Aid off right here - your dealership is very wrong and your 2017 Ford F-150 can absolutely have a trailer brake controller installed. They are wrong about not being able to add one and wrong about there not being a module/wiring connection. It is up and under the dash on the right side; I have added a photo from an install we did on a '17 F-150 showing the port. That said, I don't recommend using the Curt Echo # C51180. The reason why is 2015-2017...

    On your Ford 2010 F-150, the harness location should be located under the dash, above the brake pedal and taped to another harness. If you have the shifter in the center console of your F-150 it will be located under the center console. I have attached an installation video which will walk you through the installation process.

  • 2019 F150 Trailer Brake Controller Wire Size
    I'm not entirely sure a relay is used on that circuit, but it would provide a good explanation for the smaller wire gauge used on the factory pigtail. There's really no need to hardwire the controller. If the small wire gauge concerns you, there's an aftermarket one available, part # 22292. The black power wire and the blue brake output wire are both 12 gauge and the red stop lamp switch wire and the ground wire are both 16 gauge. This harness is designed for use with Tekonsha brake controllers,...

  • Is The Curt TriFlex Trailer Brake Controller Compatible With a 2010 Ford F-150?
    Yes, the Curt TriFlex Trailer Brake Controller # C24VV can be used on your 2010 Ford F-150. As you have the factory tow package you only need the Curt Custom Wiring Adapter # C51436 to connect to the factory connection under the dash.

  • How Does Brake Controller Install in 2012 Ford F-150
    When installing the Curt Discover part # C84VV with the harness for your 2012 Ford F-150, part # C51436 all you'd have to do is plug in the controller and harness and you'd be set if you have the factory 7-way like it sounds like you do. It's really a pretty simple install. Otherwise you'd need a 4-way to 7-way adapter like part # 37185 and you'd have to run the wire from the truck's frame rail to the adapter and you'd be set. See attached picture for more info on that.

    Yes, that's correct. To install the Curt Spectrum, part # C51170, or any brake controller you can use a custom harness to just plug it in. The harness is part # C51436. We don't have a video that shows the location of the connector but it's too the right of the steering wheel.

  • Hardwiring in a 7-Way Trailer Connector and Brake Controller on a 2018 Ford F-150 w/Factory 4-Way
    I did some checking and right now, in order to add a 7-Way trailer connector to your 2018 Ford F-150, you will need to use our hardwire kit # ETBC7. The factory brake controller wiring harness might be in place but if it is for sure and if that means you can install the Ford brake controller I cannot answer. I am sure you can though because I know in other Ford F-150s you can. Or you could install an aftermarket brake controller using wiring harness # 22292 and a Tekonsha brake controller....

  • Recommended Out of the Way Brake Controller for 2009 Ford F-150 With Factory 7-Way
    The Curt TriFlex Trailer Brake Controller # C24VV with Wiring Adapter # C51436 is a very good option for your 2009 Ford F-150, though to mount it you will need to use the included mounting bracket and screw it in under the dash. If you (understandably) don't want a brake controller unit in the cab of your F-150, you do have a great option I recommend checking out, the Curt Echo Mobile Trailer Brake Controller # C51180. The Echo is the best option because it will simply plug into the 7-way...

  • Can Same Harness be Used when Switching From Curt Time Delayed to Curt Proportional Controller
    To replace the existing trailer brake controller on your 2009 Ford F-150 with a Curt proportional unit, such as the Curt TriFlex # C24VV, you can indeed use the same Plug-In Adapter part # C51436 that you used before. You will just need to unplug your old unit and plug the adapter end into the new Curt controller. The TriFlex is a really nice, proportional controller that will activate the trailer brakes at the same time and with the same intensity that you apply to them in your F-150....
