Curt Accessories and Parts - C51436

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 behind your vehicle'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 behind 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 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.

Video Transcript for Curt Brake Controller C51436 Review

Today we're going to take a look at the Curt Custom Wiring Adapter for Trailer Brake Controllers with the Dual Plug-In number C51436. This plug-in adapter works for Ford F-150s and allows for a quick, simple installation of your electric, trailer brake controller. Thanks to these two plug-ins there's no need for cutting or splicing. The custom connector end plugs into the built-in port behind the dash of your vehicle, that's this end here. The other end right here plugs into the back of your electric brake controller. It's compatible with time-delayed and proportional brake controllers from Curt.

The brake controller must have the built-in plug for the adapter connect. This will not work with connectors with pigtail wiring harnesses. It is two-feet long and features 12-gauge wires that have a protective covering like you can see here, to help prevent damage. It does have a limited one-year warranty. We're going to bring out our Curt Brake Controller here.

This is the Curt Reflex. Show you how this is going to work. As I said, this end will go to the port under the dash of your Ford F-150. Then you will just plug this in as such. That should about do it for our Curt Custom Wiring Adapter for Trailer Brake Controllers with the Dual Plug-in number C51436.

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. 115344

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.

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. 258882

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. 107754

  • 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....

  • Installation of Brake Controller and Brake Controller Wiring to Added 7-Way in 2018 Ford F-150
  • For your 2018 Ford F-150 I don't recommend the Curt Venturer brake Controller # C51110 but it will install in the same way as any other brake controller and for that installation you have a couple different options. If when you installed the 7-way you grabbed the factory wiring for your 12V and brake controller from near your driver's side wheel well, then I recommend using the wiring harness # C51436 which will connect to the factory port under your dash. Some models don't have the brake...

  • Parts Needed to Install Curt Venturer Brake Controller in 2018 Ford F-150 with 7-Way
  • To install the Curt Venturer brake controller part # C51110 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.

  • Which Curt Brake Controller Adapter Fits a 2015 Ford F-150
  • The Curt adapter, part # C51436, fits your 2015 Ford F-150. It plugs into the factory connector under your truck's dash and fits most Curt brake controllers, like the Venturer part # C51110. I've linked a video of a controller being installed into a 2013 F-150 using the # C51436 adapter.

  • Location For Brake Controller Adapter # C51436 To Plug Into On 2010 Ford F-150
  • On your Ford 2010 F-150, the harness location should be located under the dash, above the brake pedal and taped to another harness. I have attached a photo that shows the typical location for the harness location on your truck. If you have the shifter in the center console of your F-150 it will be located under the center console. I have attached the installation instructions for the Curt Custom Wiring Adapter, part # C51436. The instructions show the typical installation locations for...

  • 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...

  • The Curt Venturer Brake Controller # C51110 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.

  • Installation of Curt Venturer Brake Controller # C51110 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...

  • How Does Brake Controller Install in 2012 Ford F-150
  • When installing the Curt Discover part # C51120 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.

  • Brake Controller Wiring Adapter for 2014 Ford F-150
  • The adapter you need to install an electric brake controller in your 2014 Ford F-150 depend on which controller you have. If you don't already have a controller I recommend the Prodigy P3, part # 90195, because it's the easiest to use and install. For the P3, or any other Tekonsha controller use part # 22292 for the adapter. A few other popular brands: For Hayes controllers use part # HA81794-HBC For Hopkins controllers use part # HM47845 For Curt controllers use part # C51436 If...

  • 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 # C51140, 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....

  • Brake Controller Install Harness for Curt Triflex to Install In 2017 Ford F-150

  • 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. Another option is to use the Prodigy RF, # 90250, which mounts on the trailer so you will not have to modify the rental truck...

  • 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 # C51140 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...

  • 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 # C51140 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.
