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)

2008 Dodge Ram 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 Dodge Ram 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.
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.

Do you have a question about this Trailer Brake Controller?
- Troubleshooting OverLoad Code on Brake Controller With Trailer With New Wiring
- It sounds like you have bad trailer brake magnets on your trailer. Having a bad magnet can cause the problem you described and based on what you mentioned it would be the most obvious issue.
I attached a help article that details how to troubleshoot trailer magnets.

- It sounds like your brake controller is catching a signal on the brake controller output wire in a different way when it is cold. This can be due to corrosion or even a little additional moisture in the connection.
The flashing LED display is not an indication of your Curt Triflex brake controller # C24VV going bad. If it were going bad, you would have that continue after the vehicle is warmed up as well. You can most likely solve the issue with a little sand paper or steel wool
view full answer... - Troubleshooting Curt Triflex Brake Controller Displaying Numbers When No Trailer Is Connected
- Your Curt Triflex # C24VV should not display anything but a single dot when the trailer is not connected. You are getting numbers when your apply your brakes because there is a draw on the brake controller output wire. The controller sees that power draw as a trailer being connected. I recommend you clean your trailer connector on your truck as sometimes dirt or corrosion can cause a small draw from the other pin functions. You can use sand paper, steel wool, or even an old toothbrush
view full answer... - Curt TriFlex Brake Controller AE Error that Caused Error Messages on a 2016 Mazda CX-5
- The first thing you will want to do is have the error codes showing up on the vehicle cleared by a mechanic. When a vehicle throws codes like that they stay in the computer memory so disconnecting the controller won't stop the error messages from appearing.
It does sound like something may not have been hooked up quite right but it could also be an internal issue with the controller (more on that below). On the 2016 Mazda CX-5 there isn't a plug-in harness for a brake controller so
view full answer... - Troubleshooting Curt Tri-Flex Brake Controller installed on a 2009 Cheverolet Silverado 1500
- To troubleshoot your Curt Tri-Flex Brake Controller # C24VV, my first recommendation would be to check the brake controller and make sure that it is functioning properly. To do this you will need to use a circuit tester like the # PTW2993 and connect to the blue output wire on the brake controller output. Then step on the brake and make sure that the brake controller is sending signal to your 7-way. Typically, you will want the brake controller to be set to maximum output while testing.
view full answer... - Are the Curt TriFlex # C24VV and Curt Adapter # C51453 a Fit for a 2014 Ram 1500 4WD 5.7 Hemi
- You have exactly what you need for installing a brake controller in your 2014 Ram 1500.
Brake controllers, like your Curt TriFlex # C24VV, aren't necessarily vehicle specific, but the plug-in wiring adapter harnesses are. The correct one for your 1500 is the Curt # C51453 that you referenced. This will plug into the port under your driver side dash and allow you to easily install and remove the controller when needed.

- Your Curt Triflex brake controller part # C24VV can easily be wired to your 2013 Toyota RAV4 but it will require you to hardwire most of the connections.
You will need to start with a 4-way (if you do not have one). For that you would want the # 118578.
From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and
view full answer... - Troubleshooting Curt TriFlex Brake Controller that Flashes 1.0 With No Trailer Connection
- This is a common issue when there is corrosion built up on the brake output pin of the 7-way. What this does is cause the controller to sense a slight amperage draw which confuses it into thinking a trailer is connected. The other thing you can try is unplugging the controller and plugging it back in. Sometimes the Curt controllers just need to have a hard reset to function normally.
view full answer... - Troubleshooting Curt TriFlex Brake Controller No Longer Working
- The issues you're describing sound like there could be an internal malfunction on your Curt TriFlex Trailer Brake Controller # C24VV. The easiest way to test this is to sever the blue wire a few inches back from the controller itself. Then use a circuit tester like # PTW2993 to test this wire from the back of the TriFlex to see if you get power when applying the manual override.
If you don't get power, or get power at any other point other than when applying the override, then the controller
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... - Should Curt TriFlex Brake Controller be Drawing 21.5 Milliamps in Standby Mode
- All modern brake controllers including the Curt TriFlex # C24VV draw a few milliamps at idle. The Curt controllers are slightly different in their circuitry and can draw a little more than other brake controllers. This power draw is normal and it would take months of the vehicle just sitting, not ever running, for it to drain a battery.
view full answer... - Where Is Brake Controller Install Port on 2017 Ram 1500
- To install a Curt brake controller like the part # C24VV in a 2017 Ram 1500 the correct install harness is the part # C51458.
If you check out the install video I attached below you'll see exactly how a similar brake controller installs on a 2017 Ram 1500 like what you have. Fast forward to the 2:30 section of the video to see where the port is found.
view full answer... - Troubleshooting Brake Controller that Displays Numbers On Display Going Up Hills
- Sounds like the red wire of the Curt Tri-Flex part # C24VV is shorting out to the 12 volt power wire of the brake controller which is tricking the controller into thinking the brakes are on and because of that it is looking for deceleration (like going up a hill or actual acceleration) and is trying to apply trailer brakes.
Check the condition of the red wire on the controller. Make sure it is securely attached to a circuit that only sees voltage when the brakes are applied.
view full answer... - Which is Better Curt Brake Controllers or Prodigy Brake Controllers
- The Curt brake controllers aren't my favorite ones to recommend as they have a tendency to have reliability issues across basically all models from them.
The brake controller I recommend is the Prodigy P3 part # 90195 because this brake controller senses the amount of braking your tow vehicle is applying and puts a proportional amount of braking on the trailer's brakes. It also has a display that uses full words instead of codes that would have to be deciphered. It's our best selling
view full answer... - Testing the Curt Triflex Brake Controller for Power
- I recommend putting a tester on the 5 o'clock pin of your 7 way connector on your FJ Cruiser. This is the brake controller pin. Hit the manual override and see what your readings are. The Curt TriFlex Trailer Brake Controller - 1 to 4 Axles - Proportional # C24VV is a proportional controller so only the manual override can be tested accurately when still using a multimeter like # PT89ZR.

- You've started in the right direction with troubleshooting the Curt TriFlex # C24VV and Wiring Adapter # C51451 install on your 2018 Chevy Silverado 1500.
The OL code that you're seeing means that the output circuit is being overloaded which normally means that there is a wiring issue somewhere.

- The only time that you would need to have the computer on your 2018 Chevy Silverado 1500 programmed for an aftermarket brake controller is if you initially had an OEM controller installed. Since you didn't have the OEM controller, the Curt TriFlex # C24VV and Wiring Adapter # C51451 should just be a simple plug and play application.

- 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. Time-delayed like the Venturer put out a preset amount of braking power so they aren't as effective.
So instead the Triflex part # C24VV with the install harness # C51332 would be the better option for your 2005
