  • 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 controller and then plug the other end into the built-in port beneath 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 on most applications
    • 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


Note: The factory brake controller plug on certain Nissan Titan XE models has a pin configuration that does not match up with this adapter plug. To install this adapter in those vehicles, hardwiring is required.


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 in most vehicles. 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.

Used with Curt brake controller. Only giving 2 stars as I'm having issues with the controller and at this time, not sure if it could be this cable? Unlikely but can't rate this any higher since I rated the brake controller 2 stars and this is essentially part of that setup. 820019

The trailer light kit I got was very easy to install with the helpful video and instruction etrailer has. etrailer made it very easy to select the correct trailer accessories for my Frontier. They were helpful when I called and the website is very easy to use! I have made other purchases through etrailer because it is easy to use and they have what I needed all in one place.

Easy installation on a 2019 Nissan Frontier with factory towing package. I opted to screw the controller to the left side bulkhead. The control knob mounted on the dash looks like it came from the factory. Much nicer than a controller slung to the bottom of the dash. 764597

  • Where to Connect the Adapter to Install a Curt Brake Controller in a 2017 Nissan Pathfinder
    To install a Curt Brake Controller, like the Discovery # C51120, on your 2017 Nissan Pathfinder you will simply need to plug the Custom Wiring Adapter # C51382 under your dash like you mentioned. I am attaching a video where one of our install guys installed a Tekonsha Prodigy P2 # 90885 in a 2013 Pathfinder using the Tekonsha Wiring Adapter # 3050-P. If you skip to the 2:45 mark you can see where he plugs in the adapter for the Prodigy P2. Your Curt adapter will plug into the same place.

  • Availability of Curt Brake Controller Plug-In Harness for 2018 Nissan Armada
    I spoke with my contact at Curt regarding a brake controller plug-in harness for your 2018 Nissan Armada. If you had previously used the Custom Wiring Adapter # C51382 for the controller in your Pathfinder, this same harness should carry over to your 2018 model Armada without issue. They have not been able to physically test/confirm the fitment simply because they have not yet had access to the 2018 model vehicle, but there have been no generational changes between the model years so...

  • Recommended Curt Brake Controller Wiring for 2017 Nissan Titan
    If you have a factory 7 way in your 2017 Nissan Titan, then the Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In # C51382 is all you need for your brake controller. If you don't have the factory 7-way, then you will use that same harness and then also the Factory Style 7-Way and 4-Way Flat Vehicle End Trailer Connector # N40975.

  • Curt Brake Controller Install Harness Recommendation for 1999 Ford F-250
    For installing a Curt brake controller like the Triflex part # C51140 in your 1999 Ford F-250 the correct install harness is the part # C51322 which is a confirmed custom fit and would work well.

  • Recommended Brake Controller for 2018 Nissan Titan With Factory 7-Way
    For your 2018 Nissan Titan I very strongly recommend going with the Redarc Tow-Pro Elite # 331-EBRH-ACCV2 over the Curt Spectrum # C51170, which does use Wiring Adapter # C51382 to connect to your 2018 Nissan Titan. The Redarc Tow-Pro # 331-EBRH-ACCV2, which you can install in your '18 Titan with Wiring Adapter # 3050-S, is by far the superior option because it is not only extremely effective and responsive but its manual control knob makes it simple to use; the Tow-Pro can also be mounted...

  • Recommended 7-Way and Brake Controller for a 2019 Nissan Frontier
    The wiring that I recommend installing on your 2019 Nissan Frontier so that you have a fully functioning 7-Way is the Tekonsha T-One # 118266 because it is the most reliable option available. This comes with the wiring and relays needed for the installation but you may be interested in the mounting brackets # PK12711U and # C57202 as well to easily mount the 7-Way. If you don't already have a brake controller then I recommend going with the Curt Spectrum # C51170 because it is a proportional...

  • Troubleshooting 7-Way Trailer Connection Wiring on 2017 Nissan Frontier
    In your 2017 Nissan Frontier, the Curt brake controller should be installed using the custom wiring adapter # C51382. This should work correctly to give you the proper wiring within your cab. Then you will use the Curt # C56226 or the Tekonsha # 118266 to get the correct 7-way. If you have done this even using the previous relays, check your trailer connection for functions using the attached photo and a circuit tester like # PTW2993. It sounds like the trailer may be mis-wired...

  • How Can I Tell if My 2013 Nissan Pathfinder Came With Factory Tow Package
    All 2013 Nissan Pathfinders came pre-wired for a tow package, so we know your Pathfinder at least has something. If your Pathfinder came with the tow package option from the dealer, then you would have a trailer hitch and trailer wiring at the back of the Pathfinder. Since you are asking for a wiring kit, I'm guessing you need the wiring still. For this I recommend the Curt 7-Way Wiring Harness, # C56357, if you want a 7-pin trailer connector or the Curt 4-Way Wiring Harness, # C56281,...

  • Recommended Brake Controller Wiring Harness and Installation Location on 2018 Nissan Titan XD
    If your 2018 Nissan Titan XD has the factory 7-way trailer connector then there is a custom wiring harness for your brake controller. If you will be using a Draw-Tite, Tekonsha, or Reese brake controller you will use # 3050-P. For Curt use # C51382 and for Hopkins use # HM47635, and for Hayes use # HA81786-HBC. The factory harness you connect to will be located underneath and to the left of the steering column taped to another harness near the emergency brake pedal. It will be a 6 pin...

  • Brake Controller Recommendation for a 2006 Nissan Titan for Tent Trailer
    The Curt Venturer part # C51110 would have plenty of braking power to activate the brakes on the tent trailer you are purchasing. This controller can activate up to 3 brake axles so it would be more than powerful enough. I do have a better option for you though. The controller you referenced is a time-delayed controller. Which means that it applies a preset amount of braking power at a preset speed every time you touch the brakes. That can work out decently, but in reality rarely do...

  • Troubleshooting Brake Controller that Says Not Connected to Trailer
    Since your trailer's brakes worked on another truck that would indicate that the problem is on the truck side of the equation. First and easiest thing to check is to check for corrosion on your truck's 7-way. Some fine grit sandpaper can easily remove any corrosion that would prevent the connetion from being made. Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide....

  • Recommendation Between the Prodigy P3 and Curt Spectrum Brake Controllers for a 2008 Infiniti QX56
    Both the Tekonsha Prodigy P3 # 90195 with the Adapter # 3050-P and the Curt Spectrum # C51170 with the Adapter # C51382 are excellent brake controllers and I wouldn't hesitate to recommend either one for you to use with your 2008 Infiniti QX56. Even though they are both electric brake controllers the P3 is more of a traditional controller while the Spectrum is a new style of brake controller. Ultimately I recommend going with the Spectrum over the P3 because you can install it just about...

  • How to Set a 2012 Nissan Frontier Up for Towing a Trailer with Brakes
    You are correct in that you will need to use a brake controller in order to operate the brakes on a trailer. The Curt Venturer Trailer Brake Controller part # C51110 is a fit for your 2012 Nissan Frontier and will not require any splicing so long as you also use the Curt Custom Wiring Adapter part # C51382. The relays and jumper harness that you are referring to are not included with the brake controller and will need to be purchased separately. If your Frontier came with a factory 7-way...

  • 7-Way and Brake Controller Recommendation for 2007 Nissan Xterrra
    If you install the Curt 7-way part # C56226 on your 2007 Nissan Xterra you can install a Curt brake controller with the correct install harness part # C51382 for your vehicle. This will allow you to install a Curt Triflex part # C51140. It would be a plug and play option without requiring any hardwiring.

  • Troubleshooting Curt Venturer Brake Controller on 2008 Nissan Xterra with No Lights
    I spoke with my contact at Curt and he said it sounds like a problem with the wiring on the trailer, probably a bad ground. His advice was to make sure the trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or...

  • Curt TriFlex Trailer Brake Controller Does Not Power On
    First, lets just make sure you are using the correct wiring harness. For a 2012 Nissan Pathfinder it is # C51382. What you will want to do is check the black wire. There should be power on the black wire leading to the controller. If there is no power leading to the controller then you will need to check the owners manual for all of the fuse/relays locations related to the tow package wiring and brake controller wiring. Chances are that it is just missing a fuse or relay. If you are...

  • Curt Tri-Flex Brake Controller Shows Voltage on Blue Wire When Plugged In on 2008 Nissan Frontier
    First, if your 2008 Nissan Frontier has the factory installed 7-Way trailer connector then make sure you are using the proper harness for the Curt brake controller, # C51382. On the end that plugs into the truck, make sure the wires are in the same positions as the ones in the picture I have included. If something is out of place it will need to be moved. If you hardwired in the brake controller then I suspect that there needs to be a more substantial ground and/or the red wire is not...

  • Are Relays Needed to Install a Brake Controller in a 2006 Nissan Frontier
    Relays are used to activate circuits or provide power for them. In the case of your 2006 Nissan Frontier some owners of Frontiers have had to add a few relays to activate the trailer wiring circuits. If all of the tail light functions work on your trailer when connected to your Frontier then you would not need any additional relays. Most likely this is the case since whoever installed the 7-way on your vehicle would have wanted the 7-way to work. If you needed the relays you would...

  • Curt Spectrum Brake Controller Install 2018 Nissan Armada with Factory Tow Prep
    In order to use your Curt Spectrum Trailer Brake Controller part # C51170 in your 2018 Nissan Armada you need the Curt Custom Wiring Adapter part # C51382. One end plugs into your Spectrum Brake Controller while the other plugs into the factory harness located under the driver side dash, to right side of the steering column and above the accelerator. I included a photo of another brake controller harness being plugged into a similar Armada and some video reviews of the brake controller...

  • Can a Brake Controller be Installed on a 2014 Nissan Frontier with Aftermarket Remote Start
    If the remote start uses the CHMSL or stop light circuits then it is possible that using the brake controller could blow that fuse if the circuit is overdrawn. But considering that a remote start is only using the brake signal to shut down the motor before using the key to restart it the chances of that happening are slim to none. If you want to use Curt controller # C51110 then you will need wiring harness # C51382 to plug it into your 2014 Nissan Frontier.

  • Upgrade 4-Way to 7-Way Adapter for a 2015 Nissan Xterra and Recommended Brake Controller
    The harness and 7-way plug that you suggested # 118267 is a compatible upgrade for your 2015 Nissan Xterra that currently has a 4-way plug. You'll just need to plug-in with no additional wiring needed. The Curt Brake Controller with Adapter # C51110, # C51382 is also compatible fit for your Xterra. If you're interested in a brake controller with all the bells and whistles, I recommend the Tekonsha Prodigy P3 Brake Controller with Adapter # 90195, # 3050-P. It's the latest version...
