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.

For the most part I have been very happy with the merchandise that I have ordered from etrailer. But right now, I think that the people pulling the orders have to slow down a little and look closer at the details. I had ordered a C51382 cable but was sent a C51362 cable. They are not inter-changeable. They are shipping a new cable today (Tue.) I am supposed to get it by Thursday, depending on what time it gets here I may be able to get it done Thursday night and then calibrate the brake controller. Otherwise I am supposed to be on the road Friday but first I will have to take care of this and calibrating the brake controller on top of everything else.

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.

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.


Comments
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.

This worked well with the nissan NV 3500 passenger van pre-installed trailer wiring

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.



- C51382
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.

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.


Comments
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.

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.

2014 Nissan Frontier

recently purchased a Curt Venturer Brake controller with wiring harness for my 2014 Nissan Frontier. installation was as easy as shown in the video. after hooking up camper, initial brake setup and test drive was 10 minutes! everything should be this easy!

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.

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

Awesome! Made controller install a 5-10 minute project.

I could have bought for the same price the one that plugs in series between your 7-way, but I liked the more permanent solution and didn't want to control it from my smartphone. Very pleased with the factory like look in my Nissan PRO4-X.



- C51382
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.

Great product!! It took a total of five minutes at the most to drill and hook up the wiring harness. Took the TT to get tires and the test drive was complete. Thank you etrailer for a wonderful product.

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.

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!

I have used this on two different vehicles to pull a popup camper, R-Pod camper and a tandem axle enclosed trailer. This has performed perfectly every time I have used it and I have been very satisfied with my purchase.

I use this in conjunction with a Curt controller in my 2011 Xterra Pro-4X. It all works great.

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.

  • 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...

  • Redarc Brake Controller for 2014 Pathfinder
    Yes, the diagram is correct. Please also note the attached "official version" from installation instructions. Only the black wire needs to be pulled from the TPH-014 and run to the battery with the breaker fit inline. The remaining wires within the TPH-014 can be left in place and the Tow-Pro harness plugged into the vehicle trailer brake connector. I verified this with the Redarc too just to ensure.

  • 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....

  • 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 if...

  • Troubleshooting 2018 Nissan Frontier SV with Brakes that Lock Up when Key is Turned On
    The brake controller and the brake controller wiring you mentioned does not affect the 12 volt accessory circuit of the 7-way that you are wanting to use to charge your trailer battery. Now with that said if your trailer brakes are locking up as soon as the ignition comes on that to me indicates that you have the brake output and the 12 volt accessory circuits either wired backwards (most likely) or there's a short between the two circuits. The 12 volt accessory circuit should be in the...

    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...

  • 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.

  • Troubleshooting Brakes Activating With Headlights On, TriFlex Brake Controller, 2012 Nissan Frontier
    The Curt TriFlex Trailer Brake Controller Item # C51140 is not going to work properly on your 2012 Nissan Frontier if you are using a factory plug and play wiring adapter. If you are, the red wire from the brake controller should not be connected to the green wire. These wires connected cause the power to jump circuits. To get the proper functions out of the brake controller it would require the Curt Custom Wiring Adapter Item # C51382.

  • 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 want...

  • 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 people...
