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.

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.
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.

See what our Experts say about this CURT Trailer Brake Controller
- Should Numbers Flash on Curt TriFlex Trailer Brake Controller without Trailer ConnectedI checked out the owner's manual of the Curt TriFlex Trailer Brake Controller part # C24VV for you and on the fifth page it states, "If a trailer is not connected the output setting is flashed when the brake pedal is pressed or the manual control is actuated.". Therefore, the scenario you described is normal according to the manual. I suggest giving this a read to better understand how your controller works. I have attached it below.
view full answer... - Curt Triflex Brake Controller Intermittent Error Code Trailer Not ConnectedYou are correct in your thinking that the problem is not the trailer since the brakes work properly when hooked up to the neighbor's truck. The issue is most likely the ground on the trailer connector on the Yukon or the Curt Triflex itself part # C24VV. It sounds like you have checked your connections and grounds but it is a good idea to make sure the trailer connector on the Yukon is grounded to clean bare metal surface and that the brake controller itself is grounded properly. The brake...
view full answer... - Recommended Brake Controller for 2014 GMC Sierra 1500The Curt # C24VV TriFlex brake controller you'd looked at would be a good choice at a reasonable price. The proportional controller will provide safe, reliable and predictable braking and is compatible with both electric and electric over hydraulic braking systems. You'll also need the # C51451 brake controller wiring harness. The wiring harness plugs into the junction box located on the firewall to the left of and a bit above the brake pedal as shown after the 2:30 mark in the linked...
view full answer... - How To Install Trailer Brake Controller On 2004 Nissan Xterra Without Tow PackageIf your 2004 Nissan Xterra doesn't have a factory tow package then there will be no brake controller wires under the dash to hook up to. Instead, you will need to hardwire the controller. In addition to a controller like the Curt TriFlex Trailer Brake Controller part # C24VV you will need the Wiring Kit for 2, 4, 6, and 8 Brake Electric Trailer Brake Controllers part # 5506. We do offer a complete kit with trailer connector as well, part # ETBC7. I have attached a help article that will...
view full answer... - Curt Trailer Brake Controller Only Works with Manual Override on a 2014 Toyota TundraWhen a brake controller works with the manual lever but not with the brake pedal that usually indicates a problem on the red wire. The red wire is the input wire that tells the controller you are stepping on the brake pedal. The most common issue with the red wire is actually a blow stop light or CHMSL fuse. Use the owners manual to find the stop light or CHMSL fuse to check it. You will also want to test the red wire using a circuit tester such as # PTW2992. With the brake pedal pressed...
view full answer... - Trailer Brakes Lock Up After Installing Curt TriFlex Brake ControllerIf your trailer brakes are locking up with the Curt Tri-Flex Trailer Brake Controller # C24VV, I have to start with checking to ensure you have adjusted the brake setting on the controller to something other than the highest settings, which can result in aggressive braking. 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...
view full answer... - Troubleshooting Brake Controller Not Showing Connection on 2016 GMC AcadiaSo in order for a brake controller to not sense a trailer connection that means that there is a break somewhere on the blue wire of the controller back to the trailer's brakes. Typically this is a dirty or bent brake output pin on the connector of the vehicle. Have you checked the condition of the 7-way pins on the vehicle? Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual...
view full answer... - 7-Way and Brake Controller Recommendation for 2007 Nissan XterrraIf you install the Curt 7-way part # C56226 on your 2007 Nissan Xterra you can install a Curt brake controller with the correct install harness part # C51382 for your vehicle. This will allow you to install a Curt Triflex part # C24VV. It would be a plug and play option without requiring any hardwiring.
view full answer... - Troubleshooting Curt Triflex Brake Controller Not Working After Battery ChangeIt sounds like your Curt Triflex # C24VV has a power wire short or an inline fuse or circuit breaker issue when you changed your battery. I recommend using a circuit tester like # PTW2993 to test the power wire (black wire) on your controller to ensure you have power coming to your controller. Next check your (white) ground wire to ensure connection. I've attached the installation details for you to check the codes on your brake controller and have also attached some articles to assist...
view full answer... - LED Display on Curt C24VV TriFlex Brake Controller Only Reads 3 With Output Turned Up All the WayAccording to my contact in the Tech Services department at Curt Manufacturing, what you're seeing with your # C24VV TriFlex is most likely caused by having the output or gain of the controller turned all the way up with the sensitivity turned all the way down. If you increase the sensitivity, you'll see more voltage output displayed. I would be curious to know why you have the controller output turned all the way up? You'll want the controller to apply enough voltage to the trailer brakes-...
view full answer... - Troubleshooting Curt TriFlex Brake Controller Showing Overload ErrorThis The OL error you're seeing means that there is a short somewhere in the brake output circuit, which is the blue wire that exits the rear of the controller. The usual cause of this is a corroded or damaged trailer connector, but because this is a recent installation on an almost new vehicle, that's probably not the case. In the install, you ran the gray two-wire cable from the rear of the vehicle. The white wire in the cable should be connected to the blue wire on the 7-way connector...
view full answer... - What Problems Does the Curt Triflex Brake Controller Have with 7-Ways With LED Test LightsWhat happens is that the load that LED puts on the brake output circuit tricks the brake controller into thinking that there is a trailer connected and the brake controller will start activating regardless if there is a trailer connected or not. Technically it would work just fine with a trailer, its just that it will always activate regardless if there is a trailer back there or not. I attached installation instructions and an install video for you to check out also.
view full answer... - 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.

So you'd have to go with a proportional controller like the TriFlex part # C24VV. The 2013 Ram 1500 has "Powernet" and utilizes multiplex wiring that is different from previous models. Although the brake control connector is physically the same as the 2010-2012, the...

- Will Curt TriFlex Trailer Brake Controller Work On 2020 Ram 3500 With Factory Brake ControllerThe Curt TriFlex Trailer Brake Controller part # C24VV is a fit for a 2020 Ram 3500 when used with the Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51458 but you must take the truck to the dealer to have them flash the PCM. 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.

Your vehicle needs to have a working 4-pole flat connector in order to install the # ETBC7. The 4-pole plugs into the supplied 7-way. If your Acadia has the tow package with factory 7-way you will not need the # ETBC7. GMC no longer provides...
view full answer... - Comparing the Curt Reflex and Curt TriFlex Trailer Brake ControllersThe main difference between the Curt Reflex Trailer Brake Controller part 51130 and the Curt TriFlex Trailer Brake Controller part # C24VV is that the TriFlex has a triple-axis accelerometer with nine boost settings and the Reflex has a dual-axis accelerometer with four boost settings. The triple-axis accelerometer is going to provide more uniform braking than the dual-axis accelerometer and the extra boost settings are going to allow you to really fine tune the braking power output to...
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...
