Most brake controllers clutter up the cab or get in the way, but this one hides completely under the dash. The main box is only 3-3/8" long x 3" wide x 7/8" thick and mounts out of sight with an adhesive pad or zip ties. You don’t lose knee room or hit anything when getting in and out. Once it’s tucked away, the Bluetooth connection links right to your phone — no knobs or screens needed in the cockpit.
Instead of reaching for a bulky controller, you set and monitor everything from your smartphone. The OneControl app connects by Bluetooth and lets you adjust max output, fine-tune sensitivity, and hit manual override with a single touch. You can save multiple trailer profiles, so if you tow different rigs, your settings are already dialed in. The brake output indicator shows how much power you’re sending to the trailer brakes, keeping you aware of every move right from your screen.
Proportional braking means your trailer responds exactly like your vehicle. The built-in 3-axis accelerometer senses how fast you slow down and applies equal braking force to the trailer. If you brake gently, the trailer eases in; if you stop hard, it matches your intensity. It works with 1 to 4 axles and supports electric trailer brakes for steady, predictable stops every time.
Hookup takes just a few minutes thanks to the custom harness that plugs directly into your factory brake controller port. No cutting or hardwiring — just connect both ends and pair it to your phone in about five seconds. The LED on the unit shows you status and troubleshooting codes so setup is clear and quick. Once paired and calibrated, you’re ready to tow.
The Echo under-dash controller includes built-in reverse polarity and short-circuit protection for safe operation. If Bluetooth ever disconnects, it keeps working using your last saved settings. With its compact hidden design, wireless control, and proportional response, it’s a simple way to add modern braking control without changing how your truck’s interior looks or feels.

Ratings & Reviews
Easy to install once you dig out its connector from under the dash. H Ave the unit completely hidden.
The product was exactly what was required for the job. Was disappointed in shipping since I paid extra for expedited shipping and it arrived a day later than expected. I could have got it in the same time frame and saved $XX.00.
The brake controller video was very helpful. I made my choice, ordered it and received free of confusion. Thanks go to etrailer.
Installed the controller under the dash out of the way. Downloading and setting up the app was easy. I have set a profile for my trailer loaded and empty. This is a nice feature.
The app stays open while driving, so the manual brake button is visible, and easy to access, if needed.
The Curt Echo is now on my Nissan Armada and works perfectly. It was an easy hookup with the supplied harness and does its job.
Don’t even know it’s there, set it and forget it.
This is the old obsolete model of Curt Echo which has to be installed under the dashboard. The newer version, which attaches to the electrical system in the rear of the vehicle, is superior and now preferred by most trailer owners. The above version should be taken off the catalog.
This is my first proportional brake controller. Stopping is much smoother without sacrificing safety. Communication by bluetooth makes for a clean installation.
This controller took me literally 15 minutes to install with the required pigtail and my Rubicon with factory towing package installed. When I initially downloaded the app and connected, it actuated and locked the brakes. I simple deleted the app and reinstalled and everything worked normal.
Was not aware this device draws on the battery constantly. I don't daily drive my truck and have had to replace the battery twice in one month due to being drained below the point where they could be recharged. $[XX] later and this controller removed, I've not had any problems with the battery
This brake controller has to be unplugged when not in use or it drains the battery in a few days. I had to have a electrical test done in my vehicle ($XXX). The etrailer tech said the test was done incorrectly. The Chevy dealer claims it was accurate. I’m left with a problem.
Needed a brake controller I could rely on because I was pulling my camper to a site at the top of a 25% grade within a few days. Unit plugged right into the harness for the factory brake controller (with the adapter cable) on my 2014 Ford F-150,and worked perfectly. Bluetooth connectivity works through the app (rather than through the phone's "settings" icon),and connects instantly. I'm very pleased with this product.
As first time truck and pop-up trailer users, we initially purchased a cheaper brake controller that required drilling the dash. This is a new truck, so we decided to switch and spend more for the Bluetooth. etrailer was easy to work with for a return, and the Bluetooth brake controller is fantastic - so easy to use with our new trailer!
I really wanted a trailer brake controller that I didn’t have to stick an ugly knob/box hanging off my dash. This was my solution and it works perfectly. Plugged right into my Honda Ridgeline existing plug, and easily connected to the app on my phone. Nice setup.
I was looking for a trailer brake controller that did not require a permanent mounting to the dash or center console of my 2020 Jeep Grand Cherokee Trailhawk. I initially considered the wireless bluetooth controller from Curt Echo that plugs directly into the 7-pin outlet next to the tow hitch. However, reviews from individuals that tow RV trailers identified that particular option prevents the 12v battery on the trailer from charging off of the TV while connected. This would limit the RV utilization during long trips involving boondocking.
The Curt Echo under-dash controller seems to solve that problem and uses the same user interface as the Curt Echo.
Easy to install and operate; problem solved!
Easiest install ever !
Plug and play. App is easy understand and use.
My favorite is with the app and on selected active profile you can see the amount of brake amount is being applied to the trailer when the vehicle brakes are applied. I also install the manual override button. FYI: you don’t need the app on your phone open for the controller or the manual override button to work. Also another nice feature of the manual override button is the size about the size of a quarter, uses a CR2032 battery and the battery level is displayed in the app.
This was relatively easy to install under the dash of our 2021 Jeep Grand Cherokee, especially since ours has the factory Trailer Tow Package and therefore an existing pigtail connector ready to connect to the brake controller. The Curt wiring adapter made it super easy to connect the Brake Controller to the vehicle's wiring harness. The controller was easy to calibrate and worked seamlessly while we're towing a rented trailer. We used a dedicated (older) cell phone to operate it while we're towing to avoid any potential interference from other apps rather than using our regular phone on which we receive phone calls texts, etc. This was our first time towing a trailer and this easy-to-use Brake Controller helped make us feel safe and comfortable. Highly recommended.
This brake controller works perfectly for my 2014 Audi Q7! The instructions were easy to follow thereby making the installation a straightforward process. The hardest part was deciding where to install the dial. The dial has a solid and deliberate feel when turning and numerous options for fine tuning.
Worked with 2024 Audi perfectly! Perfect plug and play!
Do not buy either the Curt Under-Dash or plug-in Wireless brake controllers until Lippert fixes the phone app. I’ve used both happily with the old ECHO Smart Control app. I could use the remote manual button with the phone app not even running. As one would reasonably expect the button talked to the controller directly via Bluetooth. The new OneControl Auto app must be running and in the foreground to use the manual remote! And the most recent version of ECHO Smart Control is non-functional, it just tells you to install OneControl Auto.
The break controller worked seamlessly. Profiles are easy to set up and it has very reliable Bluetooth connectivity with my phone. Installation was really easy on my Honda Pilot!
Worked perfectly
This made for an easy plug and play installation—and even included instructions for removal is the lower dash trim panel in my Audi.
Installation instructions were not at all helpful. I don't know what they were for but they were not for a 2014 VW Touareg TDI. The cable worked but I had to read several posts on the TDI forum and watch several YouTube videos to figure out where the OEM plug was under the dash. Bottom line: you have to remove the fuse block and everything below the steering wheel and put your entire arm up underneath the dash to feel for a foam covered plug. You cannot see it, but it's there.
The instructions were clear and the cable fit perfectly in my 2019 Q7, even though the website said it would not fit. Which is a good thing because my local Audi dealership said they didn't know how when I asked them to install the brake controller. So I went home and did it myself.
