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.
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
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.

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.

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.

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

All the information I needed was on your site. Got the correct adapter cable and was able to just plug in the controller.
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.

- What Trailer Wiring Do I Need on My 2021 Jeep Grand Cherokee (Without Factory Tow Package)?For setting up your 2021 Jeep Grand Cherokee (without factory tow package) for wiring, you will first need a 4-way harness. For a 4-way that is compatible with your vehicle, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C62VR. The Curt connector will allow you to install a 7-way into your vehicle for the functions you need for towing if you need those functions. For a 7-way, once you have the 4-way installed, you need the Universal Installation...

- 2000 Chevy C3500 Brake Controller RecommendationTo 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. This comes with all of the wiring and connectors you need to get a fully functioning...

You will need the Wiring Adapter # C51458 to plug and play the controller into your factory 7-way wiring.
view full answer... - 7-Pin Wiring Harness And Brake Controller For A 2024 Hyundai Santa CruzHello Evan, I can help clear this up. The Curt T-Connector # C68JR that you mentioned is for vehicles already equipped with the factory tow package. Meaning there will be an OEM brake controller plug already present under the dash and the brake controller would simply plug right in. So, if you do have the factory tow package, you can easily install the # C68JR wiring harness. Then for example, you can use a brake controller like the Curt TriFlex # C24VV, along with the Custom Wiring Adapter...

This will replace your 4-way and give you the 7-way you need to tow your camper with electric brakes. You'll then be able to use a brake controller like the Curt TriFlex NEXT # C24VV with Wiring Adapter # C51382.
view full answer... - How Can I Be Sure My Curt Triflex Brake Controller Is Working WorrectlyHello Dan, I can definitely help with this. It is completely normal for the Curt TriFlex brake Controller # C24VV to show the current gain setting when the brakes are applied, or when the manual override is pressed. It sounds like you have the gain currently set at 9.7 which is why you are seeing this number flash on the display. So, it sounds like it is working correctly and there is no problem with the controller. I suggest trying to turn the gain down. This way you can be 100% sure...
view full answer... - Troubleshooting Trailer Brake Controller Circuit that Activates all of the TimeYou said that the brake controller output circuit was the number 2 circuit on your 7-way. If by that you mean the 2:00 position then you have the circuits flip flopped. The 2:00 position should be the 12 volt accessory circuit, not the brake output circuit. That would explain why you are getting 12 volts all the time. The brake controller circuit should be the 5:00 position. Check out the diagram I attached to see how it should all get wired up.

- Are Circuit Breakers Needed to Install the Curt Triflex Controller with the Wiring Harness # C51362Yes, when you installed the Curt Triflex Brake Controller # C24VV by using the Curt Custom Wiring Adapter # C51362 you took care of the installation completely. The circuits that are used on your vehicle wiring that the # C51362 connected to are protected with fuses so everything is good to go. I attached an install video for the # C51362 for you to check out also.

You'll be able to find the OEM connector on your Ford behind the center console controls (see attached instructions). If your F-150 came from the factory with a 7-Way connector at the back then you're good to go, otherwise if it came with the 4-Way then you also need the Universal Installation...
view full answer... - Could Curt Triflex Cause Error Message on Dash of 2019 Ram 1500The Curt Triflex part # C24VV has a reputation unfortunately as having internal issues. If when the controller is installed it causes a dash error light I'd speculate that the issue is from the controller and I would suggest going with a different controller that is more reliable with the Brake EVN # TK63VR.
view full answer... - Curt C24VV TriFlex Brake Controller Putting Out Minimal Voltage With Vehicle Brake Pedal AppliedThe 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...

Assuming you do not have the factory tow package or factory 7-way on your Grand Cherokee you need to start with a 4-way connector, the T-One Vehicle Wiring Harness # 118425, and this is something we do have an installation video for on an '08 Grand Cherokee. You will also need the Universal Installation Kit...

- Curt Brake Controller # C24VV on 2012 Honda Odyssey Showing OL Error CodeThe OL error code you mentioned indicates an short somewhere in the brake controller output circuit between the blue wire exiting the brake controller and the trailer connector. You can confirm this by severing the blue wire behind the brake controller, being sure to leave enough room to reconnect the wire. If this makes the OL code disappear, you have confirmed the short. If this is the case, you'll need to rewire the output circuit, using 10 gauge wire like part # 10-1-1. Chances are,...

This will be a plug and play connection. If you do not have the factory 7-way you will need the Universal Installation Kit # ETBC7 and a Wiring Adapter # C51515. This kit will allow you to connect a 4-way flat connector to the 7-way and provides the wiring needed to wire in the adapter for the brake controller.

Here are the parts I recommend picking up to accomplish this: - Adapter 4-Pole to 7-Pole and 4-Pole # 37185 - 10 Gauge Wire # 10-1-1 - Curt TriFlex NEXT Trailer Brake Controller # C51140 - Curt Custom Wiring Adapter # C51322

To install the brake controller, you'll need to begin with a 4 pole trailer wiring harness. You can provide one by installing # C56331. With the 4 pole in place, you'll install the controller using our # ETBC7 brake controller install kit. The kit includes every...

Since the Curt Triflex # C24VV only has the single red light we know the controller is getting power but with the 2nd red light not illuminating when connecting to the trailer the brake wire portion is not completing the circuit. You can use a Test Light # PTW2993 to check at the connector to verify if the damaged wiring is on the truck or trailer. Then you can move in either direction with the test light to...

It will plug into a factory port under the dash. If you don't want to worry about flashing the PCM you can use the Curt Echo Wireless Trailer Brake Controller part # C51180 which is plug and play and overrides the factory signal.
