  • CURT
  • 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.

Just installed a Kurt brake controller which I purchased from Etrailer last year. Having a newer vehicle I needed a different harness which made the install easy.
by:
Very handy to plug into the vehicle harness
by:
Hard to tell. For my 2018 Armada the power input and output was not reaching the controller properly. I took it to a shop that installs Curt products. They added a diode to one of the wires. They told me some vehicles need it some don’t. When the controller was in my Ram, it didn’t. After hours of diagnosis, they strongly believe my vehicle has a wiring problem. In the end I ended up getting the Curt Echo which works. A lot cheaper than going to the dealer to figure out wiring issues.
by:
It's perfect. Just plug and play as advertised.

2016 Nissan Frontier
I installed the Curt C51110 controller with the Plug & Play C51382 into my 2016 Frontier, works perfectly.

ITS BEEN A YEAR SINCE INSTALLATION, ITS BEEN IN THE SAME LOCATION, HAVENT HAD ANY PROBLEMS! GREAT PRODUCT, GREAT PRICE!

by:
I've had the brake controller in use for over a year in my 2012 Nissan Frontier. The install was easy and took about an hour. My truck is a 2WD model so I mounted the controller in the plug that is used to select between 2WD and 4WD on vehicles equipped with 4WD. So the install look like factory.

Still in service after a year. Works perfect and easy to install.

As always, the etrailer staff came through with the right part for my Nissan.

So much easier than cutting wires and crimping butt splices. Plus it make un-installation easier and doesn't void the warranty for the brake controller. the time saved was worth the money for me.

One year later and unlike my guitar hero drum kit the insulation on the wires has not cracked and fallen off yet. Plus its nice to be able to unplug the unit from the car.

by:
2004 Nissan Titan
I ordered this wiring harness because it said it would work with my 2004 Nissan
Titan. It does not. The plug on one end of the harness matches none of the plugs on the truck wiring.

Thanks for pointing this out, Russell. The factory brake controller plug on some vehicles primarily XE models do not have the 4 pins to match up with the adapter plug. The factory plug will need to be hardwired onto the brake controller adapter that was purchased.

by:
Ordered gooseneck hitch, wiring harness and break controller for my truck. Perfect fit , easy connections best purchase ever made on internet. Very good price and great customer service! ??
by:
Nissan Frontier
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. Thanks!
by:
Truly plug and go, except at the back of the truck when the trailer plug harness plugged in, the brake wire and power wire were crossed. Research explained that Nissan Frontier's are known for the unconventional switch with aftermarket wiring. I simply cut, switched, soldered. All good now.
by:
etrailers out did my expectations. I ordered a trailer brake controller and pigtail one day, and they were at my doorstep the very next day. Boy, talk about fast. My rig works great , easy as pie setup, good price ( and I did look around), no problems at all. You guys are great. I will be buying from etrailer.com again for any of my trailer and accessories. Great job guys and girls.
by:
Great product!!! Installed in a matter of minutes. Determining where to attach the control took longer than the install. Pulled the trailer on a trip on roads with several steep inclines and applied the trailer brakes sparingly on the decent. Was able to adjust with the proper brake applications needed. Worked great. Made me feel confident that I could control the trailer on any road way. I very much recommend this trailer brake control for two axle trailers.
by:
This product is easy to install with the correct harnesses. It is relatively basic, but it handled our application quite nicely. I was a complete novice when I started this project and had to learn as I went, but this is a nice brake controller.
by:
2010 Nissan Frontier
I ordered a brake controller and a wiring harness from etrailer for my Nissan Frontier. It was shipped and delivered on time. When I went to install it everything was right and took 10 minutes to install and worked great. This was my first order from etrailer but it won't be my last. It was great to get a good price and great service
by:
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.
by:
2023 Nissan Pathfinder
Works perfectly
by:
It was easy to install and works as advertised. I have never installed or used brake controllers before so I can't really give a valid star rating as I have nothing to compare it to. For that reason I will give it an average rating.
by:
Worked as described. Easy plug-and-play on my factory tow package. Shipped and delivered in no time. This company really pays attention to customer service. I will definitely use etrailer again
by:
Your company is awesome! I can’t write about the brake controller because my mechanic is putting it on today and it is the one he recommended. What I can write about is the customer service. You made ordering simple and the follow-up is fantastic. Delivery was quick and there were no delays. I will use your company again — and again. Thank you…
by:
the black side went into curt triflex excellently. the white side was supposed to be wired for my nissan, just clip in & done. but the wires were not the same and in the wrong sockets of the clip. my electrical man is currently working this out. HOPEFULLY.
by:
2019 Nissan Frontier
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.
by:
Great service, prompt delivery of the Curt brake controller and adapter. Harness adapter connected the brake controller perfectly. Highly recommend Etrailer.

  • Brake Controller Wiring Harness for 2024 Nissan Pathfinder With Tekonsha Primus IQ
    Hi Stephen! The 3050-P you looked at is the correct Tekonsha wiring harness. However, Tekonsha is for sale right now and parts aren't available. What you can use instead is the Curt # C51382 along with the Curt Wiring Adapter for Tekonsha Brake Controller # C68VV which will let you adapt it to the Primus IQ. What are you towing with your Pathfinder?

  • Recommended Plug and Play Brake Controller Adapter for a 2022 Nissan Pathfinder
    No, I am sorry we do not because Tekonsha did not make one for your 2022 Nissan Pathfinder. The Prodigy P3 Brake Controller item # 90195 includes a universal harness you can use but you'll need to cut and splice wires. Curt does have a plug in play adapter but it only works with their brake controllers. It is the Curt Custom Wiring Adapter for Trailer Brake Controllers item # C51382. It will allow you to easily install the Curt Spectrum Trailer Brake Controller item # C51170.

  • Installation of Redarcs Tow-Pro Liberty Brake Controller on Nissan Pathfinder with CAN Bus System
    Yes, per the installation instructions, your 2014 Nissan Pathfinder with the Controller Area Network, or CAN Bus system, it is recommended by the manufacturer that you use the 30-amp circuit breaker kit # 331-CBK30-EB. This, along with your Redarc Tow-Pro Liberty Brake Controller, # RED24FR and the Plug-and-Play Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers, # RED39FR (TPH-014) will have you all set. As long as your Pathfinder has the factory 7-way already. However, to add...

  • 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 # C84VV, 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.

  • 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 item # RED44FR over the Curt Spectrum item # C51170, which does use Wiring Adapter item # C51382 to connect to your 2018 Nissan Titan. The Redarc Tow-Pro item # RED44FR, which you can install in your '18 Titan with Wiring Adapter item # 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...

    Hey Dirk, the correct Curt brake controller install harness for your 2025 Nissan Pathfinder is the part # C51382. I confirmed this with Curt just now. There actually isn't a part number C51383. Do you have a Curt brake controller already?

  • 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 and...

  • Install Harness for Tekonsha Brake Controller 2025 Nissan Pathfinder
    Hey Tom, for your Tekonsha brake controller to install in your 2025 Nisssan Pathfinder you would want the install harness part # C51382 which plugs into the port under your dash. You would need to cut off the Curt side of the connector and wire it by color to the Tekonsha universal harness since we don't have a Tekonsha harness that fits your vehicle at this time.

  • Part Needed to Add 7-Way to 2011 Nissan Pathfinder
    To add a 7-way to your 2011 Nissan Pathfinder, all you need to do is add the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # C56226. This will replace your 4-way and give you the 7-way you need to tow your camper with electric brakes. You'll then be able to use a brake controller like the Curt TriFlex NEXT # C24VV with Wiring Adapter # C51382.

  • Brake Controller Recommendation for 2013 Nissan Frontier with Tow Package
    For a basic but great brake controller the Brake EVN # TK63VR would work well in your 2013 Nissan Frontier. It would install to the factory wiring of your vehicle with the part # 3050-P which plugs in under the dash. It comes with hardware to easily attach to the console as well. For a brake controller with an even smaller foot print that installs with just a small knob on the dash of the vehicle the Redarc Tow Pro Liberty part # RED24FR would be a great option that would install with...

  • 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,...

  • 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....

    Hello Hugues, thanks for reaching out. Generally, with the Curt Echo wireless controller, the error codes it throws are pretty accurate. A bit of play at the trailer connector could explain the intermittent issues you are having. Since the trailer is brand new it is hard to believe that a wiring issue would be the cause, unless it came off the lot that way. Sometimes the contacts in the vehicle trailer connector can become loose- same on the trailer side. The only real way to fix this would...

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.
