Features to know about
Saves Space in the Cab: Slim Under-Dash Design
The TriFlex NEXT keeps your interior neat with a compact controller that mounts flush to the dash and measures only 1" thick. There’s no bulky box hanging below your knees, just a clean face with simple rocker switches and a large LED display that’s easy to read at a glance. The included bracket and hardware make it simple to secure in any angle, and automatic leveling handles the rest.
Delivers Smooth, Confident Stops: Triple-Axis Proportional Braking
With its 3-axis motion-sensing accelerometer, the TriFlex NEXT matches trailer brake force to your braking pressure for natural, even stops. It automatically adjusts power output when traveling uphill or downhill so braking stays consistent on grades. The result is steady, proportional control that prevents push-pull motion and minimizes wear on both tow vehicle and trailer brakes.
Easy Fine-Tuning on the Move: Gain and Load Adjustment
You can dial in the exact braking feel you want. Set gain from 0.5 to 9.9 in 0.5-point steps using the gray rocker switch to match your trailer’s weight, then adjust load from 1 to 9 with the black switch to control braking aggressiveness. Whether you want softer engagement or a firmer response, these manual settings let you fine-tune performance without tools or guesswork.
Protects Your System Automatically: Built-In Safety Features
Continuous diagnostic checks run in the background to catch issues before they become problems. The TriFlex NEXT includes short-circuit and reverse polarity protection to defend wiring and breakaway systems. A sleep mode reduces battery draw after five minutes of inactivity and wakes the moment you press the brake pedal, keeping your setup safe and ready.
Installs Fast with Plug-In Capability: Ready for Up to 4 Axles
Automatic leveling means flexible mounting options, and if your vehicle has a plug-in brake control harness, setup is quick—just connect it and go. For other applications, a vehicle-specific harness or hardwire install can be used. This unit handles trailers with up to 4 axles (8 brake assemblies) and works with electric trailer brakes for broad compatibility.

If you don't already have a 7-way plug at the back of your vehicle, take a look at our exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately).
What is Proportional Braking?
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.

Hi everyone. Steve here with etrailer. Today we're taking a look at the CURT TriFlex NEXT trailer brake controllers for one to four axles. Now these are proportional braking controllers, and this is a package of six. So again, quantity six. So most likely if you're on this page, you're probably a dealer or something of that nature.
So again, you're gonna get quantity six of the CURT TriFlex NEXT. And as you can see, you got your manual override button right there on the side. And then, of course, it is wired with a plug factory right out of the box. And then of course you're gonna get a package of six of the cable ties and the installation instructions and the cards about the products themselves and those kind of thing. Now these are gonna be a pretty fast, quick, clean installation as they mount flush.
They're about just one inch thick, and they're gonna fit nice and neatly right below the dash. And these will give you reliable power at any grade. So they have what's called a three-axis accelerometer in here. It's gonna adjust breaking uphill or downhill just the same without no issues. And again, with this automatic leveling and rocker switches, you're gonna simply tune that gain and load with ease.
And that's right up here on the front here with the buttons. Again, little rocker switches. So very easy to use. Again, if you're a dealer, obviously you're probably watching this. This is a great option to get six of these at a better price than just one.
And as well, they do display in a nice bright LED display to show those settings, error codes, and the trailer statuses. And as always, if you have any questions about this or any product, reach out to us here at etrailer. We're more than happy to assist you. I'm Steven. Thanks so much for watching, and have a great day.

Etrailer put their name on it so it has to be good correct? Yep it it. Installed it in my 2022. The vehicle has the factory trailer wiring so connection was easy with the enclosed harness. Plugs is right underneath the steering column. Double sided 3M tape LETS you stick it wherever you want. The unit powered right up and the directions for operation are quite clear. Use the mode button to cycle through the functions and the plus minus button to increase or decrease settings

Thanks for the awesome write-up, Francis! Sounds like you had a smooth install from start to finish, which is always great to hear. That plug-and-play setup really makes a difference, and having the controls right where you want them is a nice bonus. Appreciate you taking the time to share the details, and the photo too!

Very happy!
Two days after I ordered it, it was in my hands and only took about 30 minutes to install.
And it doesn’t look hokey like some aftermarket parts.
I put it below the steering wheel on the right side, which leaves 4 to 5 inches from my calf… plenty of room.
Thanks

30 minutes to install Bill, that is some pit stop speed! Glad we could get it to you quickly. What kind of trailer are you towing with it, something for fun, or more of a work trailer to make the money to have some fun?

Plugged right into my 26 Ram 1500. Was able to utilize the double sided sticky it came with as my truck is leased. So far so good

This controller is great when it’s working IE driving, controlling a trailer. But it never completely shuts off and if you don’t drive your truck or RV for a month you’ll find a dead battery. Ended wiring my starting battery to my house batteries so the solar keeps them alive but it’s still frustrating that it cost me a $250 battery.

I completely understand Rick, especially after having to replace a battery. Thank you for taking the time to share your experience. The Curt TriFlex NEXT is designed to enter a low power sleep mode when it's not in use, so it should not normally drain the vehicle's battery. If the display remains on or the controller continues to draw power after the vehicle has been shut off for a period of time.

installation was easy on my 2022 Honda Passport transport. my vehicle was equipped with the factory tow package. so the power cable that was included with the brake controller was a perfect fit to the factory plug. only thing I can say is the screws that were provided to attach the brake controller under your dash. I've been on the long side which could be a concern for some people regarding components mounted up above their – you need to be careful that these screws are not so long that they penetrate some other component up under the dash when you mount the brake controller. in my case I used my own screws that were half as long as the ones provided, just to be on the safe side. haven't pulled the trailer with it yet but it powered up and it appears that everything is working as it should.

Very easy instal with the adapter cord that came with it. Plug and play. Works great. I installed it on my 2020 Nissan Frontier and towed a teardrop camper for about 60 miles with no issues. Works a lot better than the Curt Echo that I was using previously.

The system resets after each brake pedal release. When you need it, it take 10-15 seconds to turn on, calibrate, and then start functioning. I purchased this for a 2001 F250 SD. Is the wiring harness the issue? It seems like it isn't getting power all the time, which could be the black wire not being hot all the time. I haven't checked this, but if that is the case, can I fix it myself or is their a new harness that would take care of this issue?

Hey Ryan, I agree it does sound like your brake controller is losing power and causing it to restart. I would check your brake controller fuse to make sure it isn't blown. Or to make sure it's a 30-amp fuse and not a 20-amp fuse, sometimes a 20-amp fuse is installed from the factory.

Very easy install. Plugs right in and controller mount in cab worked easily. Did not have to make any adjustments to the brake controller. The presets in the controller worked perfect.

I just drove from South Dakota to Indiana pulling a trailer tow camper. This brake controller is fantastic! After getting it set up, it worked flawlessly. No jerky stops. The truck and camper worked as one. I highly recommend this controller.

Order process was excellent, I appreciate being able to get an OEM compatable pigtail. It was a perfect fit, easy installation, worked perfectly as soon as I hooked up the trailer and took it for a test drive.

Incredibly easy plug and play. Calibrating was also simple. The customer service was stellar- eTrailer reached out each time there was a change to the delivery and responded to several emails from me about the product. Incredible company.

Worked great for my 2021 Ram 1500 Classic. A true plug and play, super easy to install. Would highly recommend to anyone needing one. Don't waste hundreds of dollars at the dealer to get one programed to your vehicle. This will work perfect

Did not work with my 2025 Tahoe. The quick connect had to be cut off and spliced. Worked great when I figured this Part out, this style shouldn’t be listed as compatible with the 2025 and newer models.
Jesse M.

Hey Chris, thanks for the feedback. The custom pigtail included with the controller is intended for vehicles with a factory tow package. If your Tahoe didn't have a factory brake control plug, this likely means you don't have the factory tow package, which is why you had to cut off the plug and splice the wires. Generally non-tow package trucks use a universal pigtail which is just 4 bare wires with no plug.

Ordering from etrailer makes it so easy. Brake controller came with the wiring harness, plugged right in my new truck and installed in 30m!

It actually installs upside down if you want it on your dash - which is a great place (left dash) on a durango, so then you have to not use its mounting cradle and uses your own method like velcro or dual lock to put it there and be able to read the display properly.

Easy to install, but not yet operating correctly. Maybe the camper wiring or brake magnets not sure yet.

I had a bit of trouble interpreting the display. I finally determined that the instructions were not accurate. I even returned one unit because the display didn't match what the instruction manual said I should see. After installing the second unit, I finally realized that the instruction manual was not accurate. The controller works great. It's really smooth and applies the appropriate braking every time.

This mounts and works great. My truck 2007 1500 Classic 4x4 with trailer package does not have a plug and play harness. I had to cut the adapter and splice the wires. This is not the parts fault. It took an extra 10 min.
