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.

Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In
part number: C51332
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 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 built-in port 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.
This adapter plugs into the port on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, and it is taped to another harness near the emergency brake pedal.
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)

2008DodgeRam Pickup
Sorry for the late follow-up. I just wanted to let you know that the brake
controller and wiring harness I purchased through eTrailer worked very well
with my 2008 Dodge Ram 2500 with the Cummins 6.7L diesel. Pictures are
attached for your use, as required.
The trailer was an 18-foot enclosed snow machine tailer with a steel
chassis. I can't remember the empty weight, but it's substantial. We towed
empty and full on dry and snow covered roads from Oklahoma to Colorado and
back. Even with th exhaust brake on my truck, I can't imagine towing this
load through the hills and mountains without a brake controller. It's been
done before, but I would say it's an unnecessary risk given the more than
reasonable prices at eTrailer...it was cheap insurance pulling such a heavy
rig with my family on board.
The controller was definitely not your top-of-the-line model, but the
adjustability and controls were more than adequate for somebody who tows
occasionally. A professional may desire more proportional controls and
adjustability, but not much more. This unit peformed flawlessly.
Thank you for your time. Please feel free to contct me if you would like
any clarification on my statements or pictures.

2007 DodgeRam Pickup
This item easily plugged into my Curt brake controller and into my truck’s factory plug. Made for a less than 5 minute install; powering up the brake controller with no issues. Convenient is an understatement with this pigtail. Rig is 2007 Dodge Ram 2500 4X4 CTD.

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.

Do you have a question about this Trailer Brake Controller?
- Curt Triflex Brake Controller Displaying d.C. Error Code when Trailer Connected
- When the display flashes a d.C. code, it means no trailer is connected (or at least that's what it's detecting). This could be either because the trailer connection has become unplugged, there is a bad pin, a bad wire or the trailer brake magnets are malfunctioning.
To start, check trailer connector and make sure both the trailer and vehicle ends are free of corrosion or rust and no pins are loose or missing. Also check for any crimped, frayed or pinched wires and repair as needed. I
view full answer... - Troubleshooting Curt TriFlex Brake Controller Keeping Motorhome from Turning On
- If your motorhome has the 2015 Ford F-450 cab and chassis that you input for your vehicle info then the Wiring Adapter # C51436 is the problem. You should actually be using the Wiring Adapter # C51432 for your TriFlex # C24VV instead.
When I spoke with my contact at Curt he said that for the Ford pickups if the wrong adapter is used then it does something to the anti-theft and keeps the vehicle from starting.

- I reached out to my contact at Curt and the display you are getting on your Curt TriFlex Trailer Brake Controller # C24VV you have is perfectly normal.
When you press the brake pedal in your truck the controller will read the power setting you have the controller set to. You can see this at the 3:20 minute mark of the included video when Ryan presses the brake pedal with no trailer connected.
view full answer... - Troubleshooting Curt Triflex Brake Controller with Straight Bar Code
- Sometimes brake controllers just need a hard reset by unplugging and plugging them back in. You might try that with your Triflex part # C24VV but you should note that this controller is prone to developing internal issues and if that does not work it would be time for a new controller which I would recommend the much more reliable Brake EVN # TK63VR.

- Since you have a 4-way in your 2019 Toyota Highlander you can install a brake controller like the Curt TriFlex Trailer Brake Controller # C24VV with Wiring Adapter # C51515 so long as you use the Universal Installation Kit for Trailer Brake Controller # ETBC7. This has a 7-way to 4-way adapter but that alone isn't enough to install a break controller. This kit also includes the necessary circuit breakers, wire and additional hardware you will need to install a brake controller.

view full answer... - Could Curt Triflex NEXT Brake Controller Drain Truck Battery
- Nope, definitely not; brake controllers, including the Curt TriFlex NEXT # C24VV will go into sleep mode after a period of time. While technically it still draws power, it is such a low amount that your battery would die from inactivity before it would drain it.
view full answer... - What Does L.4 And L.5 Mean on Curt TriFlex Trailer Brake Controller
- The L.4 and L.5 you are seeing aren't actually error codes with the Curt TriFlex Trailer Brake Controller # C24VV. Those are settings from the controller's sensitivity control, which will range from L.1 to L.9 and control the braking power you get with the controller.
view full answer... - Will Curt TriFlex Brake Controller Work on 2019 Ram 1500 Classic
- Yes, the Curt TriFlex Trailer Brake Controller # C24VV will work perfectly on your new 2019 Ram 1500 Classic. To install the controller all you need is the Plug-In Adapter # C51458 that will connect to the TriFlex at one end and to the factory port beneath the dash of your truck at the other end.
The TriFlex is a solid proportional controller with 9 sensitivity settings to fine-tune your braking and a diagnostic system that will constantly keep you up to date on any potential issues.
view full answer... - How Long Does C.C Code on Curt TriFlex Show on Display
- The display on the Curt TriFlex Trailer Brake Controller C51140 (replaced by the TriFlex NEXT # C24VV) showing C.C means that it's calibrating and will go away once it is done with the calibration. Curt doesn't list a specific time for that code to stay on.
view full answer... - Troubleshooting Brake Controller that Shows Connection When No Trailer is Connected
- Most likely what happened is that over the winter your trailer wiring connector at the rear of your vehicle developed some corrosion which is now confusing the brake controller pin on your 7-way into thinking a trailer is connected. This is very common and all you have to do is clean the pins of the controller and it should start working again.

- The L. display should show up on the Curt TriFlex brake controller, # C24VV, when it is plugged in.
The lever or button on the left side of the controller is the sensitivity adjustment. The L. should change when that lever is moved. You can also try resetting the controller by unplugging it for a few minutes and then plugging it back in (without the trailer connected). We've found that Curt controllers periodically will have odd error codes like this and resetting them takes care of
view full answer... - Troubleshooting OL Error on Newly Installed Curt TriFlex
- The "O.L." code on your Curt TriFlex # C24VV corresponds to some short of sort on the system. It would seem like what you're experiencing is likely down to one of two things;
1) there's an issue with the ground wires somewhere in what's been installed; I recommend checking the ground on the trailer wiring and vehicle wiring harnesses and making sure they're connected to rust and debris free spots on the trailer and vehicle.
2) there is an issue on the brake output wire-possibly a

If running through the set-up process again does not get it running properly, you will need to check the output from the brake wire when the manual override is engaged using a tester like the Draw-Tite # PTW2993. This will the blue

- There isn't a plug-in adapter that would allow for a simple installation of a brake controller like the Curt Triflex Brake Controller part # C24VV in your 2012 Tiffin Allegro, but from the research I did there should be a bundle of wires under your dash that a brake controller would install to.

- If your 2007 Chevy Suburban is equipped with the factory 7-Way connector at the rear then all the needed brake controller wiring is already ran under the dash but there isn't a plug there. This means to install the Curt TriFlex Trailer Brake Controller # C24VV you will just need the Wiring Adapter # C51515.
One end of the harness will plug right into the TriFlex and the 4 bare wires at the other end will need to be spliced to the 4 wires under the dash of your Suburban using butt connectors

- It is not normal from what I can read in the instructions for your Curt TriFlex Trailer Brake Controller # C24VV to flash just because your 2019 GMC Sierra 1500 ignition is switched off.
To determine if you have a defective controller you will want to take a Test Light # PTW2993 to the red wire of your brake controller to determine if the brake switch on your Sierra is activating. This would cause your controller to flash if the brake switch or wiring to it is faulty.

- I did some research on this controller for your 2006 Chevrolet Silverado, and there are no features available that will turn the Curt TriFlex Brake Controller, part # C24VV off. The best way to temporarily disable the controller when you intend to back up is to unplug the trailer. If you were to unplug the controller, it would have to be reset when it is plugged back in.

- The green connector in your truck is not the correct plug. It is normally a blue plug like what I have shown in the photo that plugs into the adapter part # C51332 if you are using a Curt brake controller like part # C51170. There will be a port to plug into if the truck came with a factory 7-way plug just to the right of the emergency brake.

Before replacing your brake assemblies entirely, start by just checking the wires to the brake magnets (if you have not done so yet) and look for wires that may be pinched or otherwise damaged and fix as necessary.

- The price for the Venturer controller part # C74VV and install harness part # C51332 is tough to beat but a proportional brake controller will be a much better option. Proportional controllers sense how hard you are applying the brakes and apply the trailer brakes the same way.
