LED Display

The LED display on the TriFlex is large and easy to read at a glance. It will show you what setting the brake controller is on as well as give you information for troubleshooting. You can adjust the screen brightness or trigger night mode so it won't glare obnoxiously on your dash.


To change any of the settings, press the silver mode button on the front of the brake controller and which mode you are currently on will show on the LED display. When you're on the setting you want to adjust, use the black rocker switch next to the mode button to adjust it up or down.


Gain Adjustment

Gain control lets you set the maximum amount of power that will be applied to your trailer's brakes, adjusting in increments of 0.5. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop. You want to go as high as you can without the trailer brakes locking up. Typically, the gain is only readjusted when you experience changing road conditions or if the weight of your trailer changes. To get more power to your brakes, press the upper rocker switch. To decrease the gain, press the lower switch. When you make your adjustment, the gain setting will show on the LED screen for 10 seconds and then go into sleep mode.


Load Control

Once you have the gain set, you can fine-tune your braking by adjusting the load control on a scale of 1 to 9. This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. Load control can get the braking power to your trailer faster and with more intensity so that it doesn't push your tow vehicle forward. If your vehicle takes too long to come to a stop, increase the setting by pressing the upper rocker switch. If it stops too abruptly, decrease the setting by pressing the lower switch. You can alter the setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.


Pinch-Trigger Manual Override

The TriFlex comes with a easy-to-reach, pinch-trigger manual override, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just push in the trigger. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.


Safety Features

The TriFlex offers key safety features to prevent damage to various components of your towing setup. This starts with built-in protection against shorts and positive and negative power reversal, as well as continous diagnostic checks to alert you to any potential problems as they come up. To minimize the drain on your vehicle's battery, the TriFlex will automatically go into sleep mode after 5 minutes of inactivity. Sleep mode will turn off again the moment you press the brake pedal.


Curt TriFlex NEXT

Quick Installation

Automatic leveling means you can mount the unit at any angle. Your mounting options are limitless, so long as you can still easily access the controller and the manual override. The included bracket is designed to mount the brake controller flush to the dash so it takes up almost no space at all.


If your vehicle already has a plug-in brake controller wiring harness, just connect the unit to it. Otherwise, you will need to purchase a vehicle-specific wiring harness (sold separately) to plug into. If a harness is unavailable for your vehicle, hardwiring will be necessary.


Note: If a custom brake control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

Proportional Braking

What is proportional Braking

The Curt TriFlex NEXT brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.


The TriFlex uses an internal 3-axis accelerometer to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In
part number: C51451

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
    • 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


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 port is located in the wiring panel underneath the dash, to the left of the steering column, near the emergency brake pedal.


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.

Arrived as planed and was much smaller then my old clunky one. The custom cable harness was easy to install. Finding a flat spot to mount the controller took the longest to find the perfect spot. I gave a five stars because every was as it said. (Plug and play)

Excellent product. Easy install. Customer service was exceptional with real-time communications every step of the way. Highly recommend e-trailer for any of your trailering needs.

Excellent product, easy installation just as described. Good quality as expected from E trailer.



by: Chris03/29/2024

The product I ordered was not available. There was a suggestion for another product, without the full knowledge that there are multiple other products, and I was only given one choice. It is what it is, if I knew of options, I would’ve made a different choice. Not a great company in terms of knowledge and service



by: Adam 02/07/2024

The control works great. The reason for knocking off a star is that the control rattles whenever there is a vibration in the truck. While annoying, it doesn't affect the operation.



by: Dennis 02/11/2024

I have not used this device yet but I have installed it. It looks kool. I hope installation orientation doesn't matter too much.

2015 Chevrolet Silverado

After talking at length (at least 15 minutes) to the rep on the phone, I choose the Curt TriFlex controller for my 2015 Silverado. It happens to be the same unit sold on Chevy's website (but cheaper on etrailor). The sales person was awesome! She wanted to be sure I got the right one, not trying to upsell me on something I didn't need. Just as she promised, it plugged right in under the dash and I even used an existing screw to mount the bracket. A 15minute install!!! I will shop here again.



by: Scott09/18/2022

I’m not sure if this part is good or not because it is part of a trailer brake choice that doesn’t work well. It is possible that this is the problem, but no one seems to be able to tell me what the problem is.

Do you have a question about this Trailer Brake Controller?


  • Where Is The Trailer Running Lights Fuse On a 2014 GMC Sierra 1500
  • For starters, the Curt TriFlex Trailer Brake Controller part # C24VV and Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51451 have nothing to do with the running light circuit. The most likely cause of this issue is a blown fuse on the vehicle. For your 2014 GMC Sierra 1500, the running light fuse is in the #15 position on the fuse box which is labeled as "Trailer Park Lamps".

  • 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.

  • Troubleshooting Curt Triflex Brake Controller Showing OL Code on Display
  • The Curt Triflex brake controller is known to have more problems than other brake controllers so I would not rule out the problem being the controller. 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. Using a circuit tester like the Quickee Tester, part # PTW2993, you should get output to the controller side of the wire you severed. If the manual slide activates

  • Parts Needed to Install Brake Controller on 2013 Toyota Tundra with Factory Tow Package
  • The only thing you'll need to install the Curt # C24VV TriFlex brake controller on your 2013 Toyota Tundra is the # C51362 vehicle-specific brake controller wiring harness. As long as the vehicle is equipped with the factory tow package, you won't need anything else. The TriFlex controller includes the necessary bracketry and hardware for installation. The factory tow package connector that the harness plugs into is located to the left of the e-brake pedal, above the kick panel as shown

  • Why Doesnt Brake Controller Have an On/Off Switch
  • Like just about every brake controller available today, the Curt # C24VV TriFlex is installed with a direct connection to the vehicle battery and does NOT feature an on/off switch. This is intentionally done for safety reasons, to ensure that the end user doesn't inadvertently forget to turn the controller on before towing. After between 10-20 minutes of inactivity, a brake controller will go into a 'sleep mode', during which time the controller will draw a miniscule amount of power

  • Troubleshooting Low Output on Curt TriFlex NEXT Trailer Brake Controller
  • It sounds like you're getting an output of 0.5 on auto. The manual setting on your # C24VV won't have an impact on the output aside from when you use the manual control. Based on what you're describing it sounds like you need to adjust the gain control which is the maximum power available to the brakes. The load control, which is the sensitivity, adjusts the aggressiveness. Even at 9 there won't be a high output if your gain setting is low. Keep in mind, this whole system works proportionally

  • Could Curt Triflex NEXT Brake Controller Drain Truck Battery
  • Nope, definitely not; brake controllers, including the Curt TriFlex NEXT # C24VV will go into sleep mode after a period of time. While technically it still draws power, it is such a low amount that your battery would die from inactivity before it would drain it.

  • Trailer Brakes Are Locking Up When Connected To My 2010 Nissan Armada
  • There are a couple tests that need to be done to determine if there is a wiring issue on your 2010 Nissan Armada with the Curt TriFlex Trailer Brake Controller # C24VV. With your trailer brakes locking up as soon as the trailer is connected it leads me to believe that the brake switch is sending power when it should not. The red wire in the Curt Custom Wiring Adapter # C51382 should only see power when the brake pedal is depressed. You can use a Test Light # PTW2992 to test this wire

  • Troubleshooting Curt Triflex Trailer Brake Controller Having Gain Numbers But Brakes Not Working
  • To determine if the issue is within the controller itself or on the trailer side of things, I recommend using a circuit tester like # PTW2993 to test the 5 o'clock pin on the 7-way connector while a friend applies the manual override of the controller. If you have power then the issue is on the trailer side, and if there is not power then the issue is between the 7-way and trailer brake controller on your 2009 Ford F-150. Since you are getting the gain number on your Curt Triflex

  • 2000 Chevy C3500 Brake Controller Recommendation
  • To add a brake controller to your 2000 Chevy C3500 I recommend the Curt TriFlex NEXT Trailer Brake Controller # C24VV which is a traditional style proportional controller that's backed by a limited lifetime warranty so it's really hard to beat the control and reliability of this controller. For the wiring you'll need a 4-Way connector, like the T-One # 118315, as well as the Universal Wiring Kit # ETBC7.

  • Curt TriFlex Brake Controller Showing L.6 Code
  • Thank you for your purchase from etrailer of the Curt TriFlex Trailer Brake Controller # C24VV. The L.6 code of the TriFlex controller means that your tow vehicle has low voltage and the tow vehicle's battery system needs to be checked. Since your brakes are locking up it could be that you also have a connector which is corroded or dirty that needs to be replaced or your wiring could have a short which is causing an issue. So you'll want to check your trailer and tow vehicle connectors

  • Will Curt TriFlex Electric Brake Controller Work with Curt 7-Way Trailer Connector with Test Lights
  • Trailer connectors that have test lights like the Curt # C57674 will sometimes cause an electric brake controller like the TriFlex # C24VV to believe a trailer is plugged in. The controller is sensitive enough to the test lights. The TriFlex will actually work just fine as long as you know that it will always think a trailer is present. If your 2006 Jeep Liberty already has a 4-way connector use # 5506 for the wiring to install the TriFlex with the Curt 7-way. If you'd rather not

  • Brake Controller For 2006 Toyota Highlander
  • I never go off the color that the wire is supposed to be. You will want to locate the brake light switch located under the dashboard. Once you have located the switch you will need to identify which wire gets power when the brake pedal is depressed. A Power Probe # PTW2991 will help you to identify the correct wire. The Installation instructions found on the Product Page # C24VV will help you identify the correct wiring required for the Brake Controller installation.

  • Should I Always Have Power On Blue Wire After Installing Curt TriFlex Trailer Brake Controller
  • The only time you want to see power on the blue brake wire from the Curt Triflex Brake Controller part # C24VV is when the brake pedal depressed in the vehicle or the brake controller manual override is activated. If the blue wire has a constant 12V then it is an indication that there is an issue with the wiring. This could lead to your trailer brakes locking up, getting hot or not working at all once you hook your trailer up. I was able to find your account and it looks like you used
