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.

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

- Troubleshooting Electric Over Hydraulic Brakes Not Activating of VehicleIt sounds like there may be an issue with the wiring in the trailer to the hydraulic brake actuator. When you installed the Adapter Module # DX35FR you did receive the trailer connected message. I have attached the instructions for the Adapter Module that shows several different wiring schematics for the popular hydraulic actuators. If yours is not listed let me know and I will help you find the correct wiring. It sounds like there may be issue with the power wire that is going into...
view full answer... - Troubleshooting Two Lines on Display of Curt TriFlex Brake ControllerTry unplugging the Curt Triflex part # C24VV for a few seconds and plugging it back in to reset it. If the problem persists the controller most likely has an internal problem and would need to be replaced. On occasion we've seen this issue be a weak power or ground wire connection too so you might check that as well.
view full answer... - Troubleshooting Curt Brake Controller that Rests When Brakes are ReleasedSo 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...

- Curt Trailer Brake Controller Displays Gibberish when Brake Pedal is PressedThe brake controller may be trying to tell you something. Take a look at the picture I have included and if what it is displaying is any of these then it is trying to indicate there is a problem. It also could be variable voltage on the input (red) wire or the sensors inside are unsure just how much braking is needed. Make sure the controller is not tilted or turned to one side. You also may need to adjust the sensitivity some (see instructions link). You will also want to make sure...

- Manual Override on Brake Controller Not Working on 2012 Chevy SilveradoThere are some tests you can do on an aftermarket brake controller to determine if it is the problem. In the truck cab you will need to sever the blue wire several inches from the back of the controller. Then use a circuit tester such as # PTW2993 to test the end of the blue wire coming out of the controller. It should only have power when you apply the manual override. If it shows power at idle, then there is something wrong with the controller and it will need to be replaced. If it does...
view full answer... - Can Curt Triflex Brake Controller Install in 1978 Chevy C30 with ETBC7 Install KitAs long as your 1978 Chevy C30 has a 4-way installed on it already you'd be set with just the Curt Triflex part # C24VV and the install kit part # ETBC7 which converts the 4-way to a 7-way and comes with everything needed to install the controller.
view full answer... - Troubleshooting Curt TriFlex Brake Controller Not Recognizing Trailer When ConnectedIt sounds like there may be a damaged wire on your 2006 Dodge Ram 2500 Laramie. 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...
view full answer... - Troubleshooting Brake Controller that Activates Intermittently When Blinkers are AppliedSounds like you are using the left turn/stop circuit from your 7-way for the brake switch wire when you installed the Curt Triflex Brake Controller part # C24VV. You would want to go back and find the circuit from the brake pedal switch that only see voltage when the brakes are applied and use it and the problem will go away. Since you used the left/turn circuit of your 7-way any time your blinker is used your controller thinks the brakes are being applied for a second and it activates...

The controller would need to be hardwired using our Brake Controller install kit part # ETBC7 and the Curt pigtail, part # C51515. To install the 7-way trailer connector, a functional 4-pole trailer connector is needed. You can install one using part # 118569. The 4 pole to 7-way adapter provided with the ETBC7 kit will plug into the 4-pole, and will have 4 remaining wires that need to be connected. Ground the...
view full answer... - Why Doesnt Brake Controller Have an On/Off SwitchLike 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 from...
view full answer... - Parts Needed to Install Brake Controller on 2013 Toyota Tundra with Factory Tow PackageThe 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...

I have linked an installation video below that shows a Tekonsha Voyager # 39510 being installed with a Wiring Adapter # 3050-P on a 2016 Frontier that shows you the location of the factory connection. If this does not look like your wiring please send me the picture you have.
view full answer... - Troubleshooting Curt TriFlex C24VV Having L.b and Error CodesI would be happy to help you troubleshoot the braking issues you are having with your Curt TriFlex Trailer Brake Controller # C24VV. There is not a L.5 error code programed into the controller but there is an L.b which indicates low voltage powering the controller. Then the -- you mentioned means that the battery is not giving enough voltage for the controller to work properly. Since you are getting both of these codes I recommend double checking the black power wire for the # C24VV....
view full answer... - Troubleshooting Curt TriFlex Brake ControllerYour Curt TriFlex Trailer Brake Controller # C24VV is not functioning correctly. It sounds like you have checked the red wire and that is functioning correctly but the blue wire is not. There should be power on the blue brake output wire when you step on your brake pedal as well as when you hit the manual override. The OL code is for overload and shows a short on that blue wire. I recommend cutting that blue wire about 6 inches back from the controller and then testing it using a circuit...

There appears to be an issue with the brake output wire sensing a trailer connection. Normally this is due to corrosion and just cleaning up your connector helps. One of the things Curt Tech often suggests is unplugging the unit for 15 minutes and then reconnecting it so it reboots. This is normally the first step with a Curt Controller...
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... - Troubleshooting Curt Triflex Brake Controller that Shows Two Red Lines on DisplayThe 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.

The reason for this is because the power wire on the 4-way harness is designed to help minimize the power draw on the vehicle's electrical circuits whereas the...

Otherwise, the issue with brakes locking up with a brake controller is that there may be an incorrect connection in your wiring. The issue is most likely that your brakes are connected to the 12 volt power on your...

There isn't a controller out there more reliable and better performing that these. The Curt Triflex part # C24VV isn't a bad controller but it's just not quite the same. One aspect is the mounting flexibility is much more limited for the Curt.
