Specs:
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 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.
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.
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.
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.
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

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.
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 behind your vehicle's dash.
Features:
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, which is located behind the dashboard. To access this connector, you will need to remove the finish panel in your dash. Plug the adapter into the connector in the large gray housing behind the panel.
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.

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)
I believe I entered the correct vehicle type and the cord did not match my 2024 e350 super duty. Luckily there were extra wiring harnesses with the new van. I spliced the correct end that matched my brake controller left behind my coin tray by the manufacturer. I was able to use the rest of the harness to the brake controller so it still was useful. Who knows. My manufacturer could have wired it incorrectly.
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.
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
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 service and speed of delivery has always been great, thank you E Trailer.
Never a problem with etrailer
Josh was excellent in listening and helping discuss my options. The trailer brake improved my driving and safety tremendously with a 14k dump trailer. Thanks, Josh.
Extremely easy to install and small enough to not be in the way. Works great as well….highly recommend.
As advertised- very easy to install!
Was easy to install and works well.

Perfect communication and quick deliver y!
Great fit works as described
install is a breeze!
I bought a weight distribution hitch w|sway control, and a trailer brake controller for my Four Winds RV. I received my order today, within a few days of placing the order. I have not installed it yet but it appears to be user friendly. Both pieces are made by Curt so the quality & performance should be good.
My thanks to etrailer & Stacy??
Ford 2013 F250.. This brake controller fit like a glove. I have a 2013 F250 and I finally found the plug behind the coin box on the dash. It fit just right and after I finally found where the factory plug was and routed all the wiring behind the dash it took about about 15 minutes to get everything working. I have use e-trailer for several projects and the shipping is amazing and they totally understand what they are doing. Thanks to all at e-trailer.

Hey guys thanks for all the help.

Thanks again for the awesome service and help

I have gotten in contact with the manufacturer and I see that part # C51432 (Curt Custom Wiring Adapter for Trailer Brake Controllers) is only a confirmed fit for the 2014 e350 Super Duty, not the 2024. So, it does not seem like it was your installer wiring it incorrectly. I am sending in this information to our fit guide team for them to get this corrected on our site. I am sorry for the inconvenience, let me know if there is anything I can do for you.
