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: C51352

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 junction box 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 electric junction box 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.


Junction Box on VehicleBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


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.

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

Scratched screen straight out of the package/from the factory. Haven't installed yet. Super fast shipping!!



by: Craig 05/14/2024

As advertised- very easy to install!



by: Pete D.07/28/2016

The Curt electric brake controller was the easiest installation I have ever had. I ordered the custom wiring adapter along with the brake controller; it all came with easy to follow instructions and it only took about 30 minutes to install the entire unit. I had done some checking around to get estimates from various companies which do the installations and their costs were around $300.00. The Curt unit including the adapter wiring was $**.00 and a very easy install. I used the brake controller during a recent camping trip on which I was pulling a 24 foot camp trailer. The controller worked great and I could easily control the trailer in some extreme mountainous terrains in Wyoming.

Bought this trailer controller cable with a Curt Trailer Brake Controller. I dont know if it works or not. I installed this along with thr trailer brake controller at the same time. Nothing works. No lights power up on the controller. I highly respect Curt Products as I have many installed on my truck, but I'm disappointed with this combo purchase.

  • Troubleshooting Curt Triflex Brake Controller that Shows Two Red Lines on Display
  • The Curt Triflex # C24VV is somewhat known for having internal bugs that make it act odd at times. The simple solution is to unplug the controller for a few seconds and then plug it back. This typically clears out the bugs and gets it working again. Try that and let me know if that fixes it.

  • Troubleshooting Curt Triflex Brake Controller that Locks Brakes Up On Lightest Setting
  • It sounds like your brake output circuit may be shorting out to the stoplight circuit of your trailer wiring and that is why the brakes want to lock up immediately. An easy way to test this is to check to see if the brakes end up pulsating when you have either blinker on. If so, then what I described is happening. Otherwise, did the brake controller's position change? Since it is a proportional controller it has to sit level horizontally and vertically to allow the controller to function

  • Comparing the Hopkins Agility and Curt TriFlex Trailer Brake Controllers
  • The Hopkins Agility Trailer Brake Controller part 47295 and the Curt TriFlex Trailer Brake Controller part # C24VV are both fine options and very similar in their proportional design. That said, I recommend the Curt TriFlex because it's physically smaller (4" long x 3-1/4" wide x 7/8" tall vs. 5" long x 3" wide x 1-1/4" tall) therefore you won't run as high a chance of hitting your knee on it getting in and out, has a built-in plug so you can remove the controller easily when needed without

  • Can the Top of the Fuse Box/Power Distribution Box Be Opened Safely on a 2014 GMC Yukon
  • You have to be careful with the fuse box or power distribution box on your 2014 GMC Yukon because if you lift that handle (or the whole box) more than 3/8 of an inch it will become disconnected from the vehicle and you will have to have it towed to a GMC dealer to get the vehicle working again! You can take the top cover off though to access the fuses and relays without any issue. You just want to avoid pulling the whole box up. I have included a link to our help article on installing

  • Troubleshooting Brake Controller With Voltage On Brake Output All the Time
  • It sounds like you are saying that your Curt TriFlex Trailer Brake Controller # C24VV has voltage on the blue wire (brake output), at all times. This would not be normal since it should only have voltage there when the brakes of the trailer need to be applied. It would be a good idea to test the brake controller at this point to determine where the problem lies. Testing the brake controller is fairly easy.

  • Curt Brake Controller Flashes Numbers when Braking and Not Towing with a 2011 Ram 1500
  • Curt brake controllers such as # C24VV can be very sensitive and it is not uncommon to get something on the display with no trailer attached. But what I recommend is to make sure the 7-Way connector at the back of the truck is clean and free of corrosion and moisture inside where the wires attach and outside on the pins. Corrosion or moisture can cause a short and cause the brake controller to do strange things.

  • Troubleshooting Curt Brake Controller that Rests When Brakes are Released
  • So the controller resets every time you apply and release the brakes? You might check to make sure you made all the connections correctly when you wired it to the correct functions. Most likely it sounds like there's an issue with the red and black wires of the controller. The black wire of the controller needs to run to a power source that is hot all the time and the red wire needs to run to the stoplight circuit. Now all of that said the TriFlex is known to be prone to internal problems

  • Troubleshooting Curt Triflex Brake Controller that Is Flashing Numbers Randomly without Trailer
  • Sounds like you have a bit of corrosion on the brake output pin of the 7-way you have on your tow vehicle. Try cleaning the pin in the 5:00 position and should see that issue go away. When a trailer senses an amperage draw (which corrosion will provide) it will think a trailer is connected and show an output setting. Also the TriFlex is known to be a bit buggy so you might also try a hard reset by unplugging it and plugging back in. I attached a link to the install instructions/manual
