Bulky brake boxes can crowd your knees or block dash access, but this one mounts nearly flush and is only 1" thick. The included bracket tucks it neatly under the dash so it looks clean and stays out of the way. Automatic leveling means it can mount at any angle, and you still have easy reach to the manual override when you need it.
The TriFlex NEXT senses your vehicle’s deceleration through a built-in 3-axis accelerometer and matches trailer braking power in real time. If you brake lightly, the trailer eases in; if you brake hard, it follows with equal force. That smooth proportional control stops push-pull motion and cuts down on wear across your whole setup. It works with trailers up to 4 axles (8 brake assemblies) and supports both electric and electric-over-hydraulic brakes.
Every trailer and load feels different, so this controller gives you full control over braking power. Use the gray rocker switch to set gain between 0.5 and 9.9 in 0.5 increments, then fine-tune how aggressively the brakes engage using the black rocker switch on a scale of 1 to 9. That lets you dial in stopping force exactly where you want it—firm for heavy loads, softer for lighter ones—without ever locking up the brakes.
The large LED display makes it easy to check braking power, sensitivity, or error codes while driving. You can dim the brightness or switch to night mode so it doesn’t glare during dark drives. Full-text diagnostics simplify troubleshooting if something comes up, helping you keep your setup safe and ready to roll.
Wiring jobs can be a hassle, but here it’s just plug-and-play. The custom-fit harness connects directly to your vehicle’s factory brake control port under the dash—no cutting or splicing required. Once connected, continuous diagnostics start running automatically, protecting against shorts, reversed polarity, and battery drain with built-in sleep mode after five minutes of inactivity.

Works very well.
This unit took less than 10 minutes to install and works flawlessly with my Grand Cherokee while pulling a Travel Trailer. Plus its low profile design made it easy to install by the hood release so I don't have a big box and display on top of my dashboard. Great product at the right price. Highly recommend this brake controller and etrailer.
Works well. The connector I got from e trailer which fits other older model Audi’s wasn’t listed to fit the 2024 Audi but fit perfectly. The Curt Triflex is an easy to use brake controller. Highly recommend!
Don't like that you have to be in park to adjust settings
stopped working at the end of 2025. Ju nk
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)
Works great and easy to install
Great brake controller for the price. Easy to install with the video. Customer service was very prompt and kind.
So far so good. Your installation video in a 2925 RAM 1500 was perfect as that is the same truck I have. Have not road tested yet but it recognized the brakes when connected to the trailer.
This controller is really responsive to braking and highly adjustable. Saved myself hundreds($800+) by going this route vs. the Mopar controller install. Great product and super easy to install and set-up!
Selected my vehicle model and they included the proper attachment without me having to search for it. Easily installed and so far it’s working great. It’s slim and out of the way and adjustments are quick and easy.
Easy install the how to video was great was able to locate the harness on my 2025 ram. My local ram dealer did not know where it was. The controller works great and easy to mount and the harness that came with it made it super easy to hook up.
Took me all but 10 minutes including pulling the kick panel in my 2025 Jeep Grand Cherokee L towing install and mount. Definitely recommend.
Stopped working half way into the trip
Works perfect in my 2026 RAM using the plug hidden behind kick panel by drivers door. Had it installed in 15 minutes.
Product was great only issue was I paid to have it Friday and didnt get it till sat and that screwed up the departure of our trip, ups fault not company, but still no refund of the extra shipping charges
Did everything it said it would! If you don’t have a factory controller for a 2025 Ram don’t waste your time and money getting one installed. This is plug and play, hooks up in the driver side kick panel. Yes it’s aftermarket but if your like me and hate going to the dealer, this is your go to option. No codes, no lights, no dealer flashing, takes ten minutes to install. Make sure you have the 7 pin plug for the trailer already installed, and you’re ready to go!
Took a while to figure it out. Have a 2003 Dodge van. Had to tow in package but didn’t have any wiring factory installed other than for the seven way. Paul it was great identifying what I need and sending it to me. Thank you very much.
Mounting bracket was broken. I was still able to use it.
This is a new model of the Curt TriFlex brake controller. As a replacement for the previous unit, it was nice to be able to install it without rewiring. The new model has a more modern style digital display that is easier to read and less annoying. The button controls are a bit less obvious than the previous model, so it takes a little effort to figure out how to adjust the system. Overall, I think it's a better unit that the previous models.
Simple and very easy to install on a 2026 Ram 1500. Lower drivers side kick panel. No tools needed. Remove and plug in. Two sided tape to the dash panel, 3 zip ties. Boom done.
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
I purchased this harness primarily to get the plug for my 2023 Grand Cherokee L Overland (with tow package). I had an Odessey brake controller with a cord for a Ford truck. The black fitting on this cord is identical to the plug coming from my brake control (both male plugs) so some splicing is required to utilize my old controller. I had difficulty locating the plug in my Jeep and could not locate photos or video of the plug location in the WL platform (current model Grand Cherokee). I have attached photos of where to locate the plug. It was a bit more forward and wrapped up with black electrical tape as shown in my photo.
If the black plug matches your brake controller, this should work perfectly for you.
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
