Most brake controllers clutter up the dash, but this one disappears. The Curt Echo Under-Dash Bluetooth Brake Controller mounts behind the dash using adhesive or zip ties, leaving nothing visible inside the cab. The compact main unit measures just 3-3/8" long x 3" wide x 7/8" thick, so it’s easy to tuck out of the way. You won’t bump your knees or interfere with airbags, and the interior keeps its factory look.
The controller connects with a custom or universal wiring adapter for simple plug-in setup. Once plugged in, it pairs to your phone in about 5 seconds through Bluetooth and finishes calibration after another few seconds when you connect your trailer. A built-in 3-axis accelerometer senses direction automatically, so you can mount it at any angle and still get smooth, even braking.
You handle everything from the OneControl app—adjusting braking output, sensitivity, and manual override right from your smartphone. The big orange manual override button on screen applies trailer brakes without using your vehicle brakes, perfect for controlling sway or slowing down on a downhill grade. The app stores multiple trailer profiles, letting you save and switch between setups instantly when towing different trailers.
With proportional control, your trailer brakes mirror how you brake. Light on the pedal gives light trailer braking; hard braking brings full force—no jerky push or pull. The internal 3-axis accelerometer senses inertia changes and matches brake pressure precisely. It works with trailers that have 1 to 4 axles (8 brake assemblies) and supports electric trailer brakes for consistent stopping power.
If Bluetooth connection ever drops mid-trip, the Echo keeps working safely using your most recent settings. Built-in reverse polarity and short circuit protection safeguard your wiring. LED indicators on the unit show system status at a glance so troubleshooting is simple and quick. You stay in control from start to finish—no interruption, no extra hardware needed.

Very easy plug and play install. Worked flawlessly with app.
I’ve bought several items in the last year from etrailer. The service and duality never disappoint!
Shipping was super quick, showed up two days earlier than expected. Easy to order and the website is easy to use.
The instructions are a little confusing. Curt provided an instruction manual that leads you to believe you need additional components to complete the install. It’s a general instruction book and needs to clarify the diagrams aren’t necessarily accurate when buying specific components.
It was a very simple install. Only problem I had was getting my fat fingers in the right position to install the adapter harness into place. Took maybe 3 minutes though. Web site said it wasn't compatible with my truck, so I called. After a short wait Jesse came on. He was extremely patient as I explained my problem and had me fixed up in just a few minutes. The shipment arrived 2 days early wich is rare these days. Very pleased for sure.
Worked great. Helped me to trace down a wiring issue with my wiring on the truck and then worked perfectly and controlled some of the heavier loads and was easy to use.
Sherry was extremely friendly and very helpful when I had questions about the correct fit for my truck. She got me the information I needed and took my order and the parts shipped the same day. I was amazed at how fast I got my order.
Easy to install once you dig out its connector from under the dash. H Ave the unit completely hidden.
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.
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!

Still 5 stars, lots of trips including a long tow of over 5000 miles. Consistently worked flawlessly. Mild annoyance that they changed the app but once I learned how the new app worked it continues to function flawlessly.
Info for this part was:
At etrailer we provide the best information available about the products we sell. We take the quality of our information seriously so that you can get the right part the first time.

I reached out to Curt about the problems with the new app. They advised that the new app runs the same as the old app it has to run in the foreground unless they are using the button which is the same as the old app. They wanted to know if you were having trouble getting past that screen. Which type of cell phone do you have and which IOS are you using?
