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


See also etrailer.com's exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.


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: C51322

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 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. For most applications, this harness is located beneath the dash, near the center console.


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)

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

They are the best at what they do. They found the parts I needed and got them to me the next day. I appreciate the dedication to their customers. This product worked for my 1997 Ford F350 with the factory-installed tow package.



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.

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

The products worked great up until about a few weeks ago Thats when I sold the truck where the items were installed. lol. Really though, I very much liked how the products listed and purchased from etrailer.com were easy to find, fit exactly as described, and performed as needed. etrailer.com is always one of the first places I look when searching for items for my new truck.

  • Curt C24VV TriFlex Brake Controller Putting Out Minimal Voltage With Vehicle Brake Pedal Applied
  • The Curt # C24VV Triflex is a proportional brake controller, which means that there are internal sensors that can determine how quickly the tow vehicle is stopping, at which time the controller will send the appropriate amount of voltage to the trailer brakes so the vehicle and the trailer will brake at the same rate. When the vehicle is NOT moving, you'll get very little voltage out of the controller with the vehicle brake pedal, just enough so the controller 'knows' there's a trailer

  • Troubleshooting Curt Trailer Brake Controller Coming On Immediately When Brakes are Pushed
  • Your Curt brake controller may have had the sensitivity adjusted to the maximum setting without you knowing. If the sensitivity is increased to maximum it may cause the issue that you are having. On a Curt TriFlex Trailer Brake Controller # C24VV this adjustment is made with the switch on the back left of the brake controller. When you adjust the sensitivity it has a range of L1 to L9 with L9 being the most aggressive activation. If the sensitivity and output are set at their correct

  • 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.

  • 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.

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

  • How To Use Curt TriFlex Trailer Brake Controller On a 2018 Ram 1500
  • The Curt TriFlex Trailer Brake Controller part # C24VV is an excellent option for a 2018 Ram 1500. That said, you'd also need the Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51458 for plug-in-play installation. In regards to the factory brake controller, these aftermarket options are much more reliable and offer better performance. There is really no comparison and many swap out the factory brake controller for an aftermarket brake controller.

  • Trailer Brakes Stop Working with P2 Brake Controller Installed on 2014 Chevy Silverado
  • It sounds like there is a loose connection somewhere, probably along the blue wire that goes from the back of the brake controller to the trailer connecter at the back of your 2014 Chevy Silverado. When they installed the brake controller did they hardwire it in or did they use the vehicle specific harness # 3016? It is more likely there is a loose connection if it is hardwired in. But if they did use the plug check where it plugs into the truck. Look for bent or broken pins at the

  • Curt Triflex Brake Controller Randomly Clicking
  • Is the controller showing any error codes when the clicking is heard? The easiest place to begin would be to reboot the controller. Unplug the harness from the rear of the controller for a few minutes then plug the controller back in, which could possibly fix the problem. If that doesn't solve the problem, disconnect the red wire feeding the controller. If the problem still occurs the controller is faulty and should be replaced. If temporarily disconnecting the red wire corrects

  • Can the Top of the Fuse Box/Power Distribution Box Be Opened Safely on a 2014 GMC Yukon
