Bulky brake boxes don’t belong in the driver’s knee space. The Curt Echo Under-Dash Bluetooth Brake Controller keeps things tidy by mounting a 3-3/8" long x 3" wide x 7/8" thick control unit out of sight beneath the dash. Everything you need is inside the box—no knobs or displays sticking out. With the plug-and-play harness and included adhesive pad and zip ties, setup stays simple, clean, and clutter-free.

No extra hardware crowding your dash—your smartphone becomes the control center. Through Bluetooth connection and the OneControl app, you handle brake output, sensitivity, and even manual override right from your screen. The app works without needing cell data once paired, supports both Apple (5.0 and newer) and Android (4.3 and newer), and even stores multiple trailer profiles so you can switch between setups fast.


Rough stops and jerky pulls disappear with proportional braking. The built-in 3-axis accelerometer senses how hard the tow vehicle slows and matches the trailer’s braking power accordingly. It works with 1 to 4 axles (8 brake assemblies) and supports electric trailer brakes for steady, even deceleration every time.
Traditional controllers mean cutting wires or awkward mounting angles. Here, a custom connector plugs directly into the factory port under the dash—no hardwiring needed. Once it’s connected, pair your phone via Bluetooth, wait for the LED to turn solid blue, plug in your trailer’s 7-way, and you’re ready to tow after a quick calibration. The system automatically sets itself up at any mounting angle for accurate braking.

Smart safeguards like reverse polarity and short-circuit protection keep wiring safe from damage. Diagnostic LEDs on the unit make troubleshooting simple at a glance. Even if Bluetooth drops out mid-trip, the controller keeps braking normally using your last saved settings—so you stay in control wherever you go.

Ratings & Reviews
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.
This is the second of these units I have purchased and installed. The quick connect ends make it soooo easy, just plug the matching ends together (NO splicing wires). I highly recommended this unit with the pigtail extender
This product was perfect for my use. The wiring harness worked just as I was told and very easy to install. I have bought several items from etrailer and everything has been good quality. The items arrive in good working working condition and in a timely manner.
Etrailer employees are very helpful and professional.
Brake controller and adaptor installed and connected in less than 10 minutes, I am very happy with the purchase and the included instructions and information.
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.
I recently bought a Kurt trailer brake controller with adaptor. I have to say, that it was the easiest thing to hook up. The product was also shipped to my home very fast. I did not think I was going to receive the package until the next week, but it came just in time to use it the following day for my work. i Love ordering products from etrailer, I have only had really great service and good products from them. I will for sure, order from them again.
I bought a weight distribution hitch w|sway control, and a trailer brake controller for my Four Winds RV. I received my order today, within a few days of placing the order. I have not installed it yet but it appears to be user friendly. Both pieces are made by Curt so the quality & performance should be good.
My thanks to etrailer & Stacy??
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.
Product installed in 5 minutes, tested and setup in 10 minutes. Shipping was fast. Superb value
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.
Ford 2013 F250.. This brake controller fit like a glove. I have a 2013 F250 and I finally found the plug behind the coin box on the dash. It fit just right and after I finally found where the factory plug was and routed all the wiring behind the dash it took about about 15 minutes to get everything working. I have use e-trailer for several projects and the shipping is amazing and they totally understand what they are doing. Thanks to all at e-trailer.

hooked right up and not any problems. 2013 F250 connectors were behind the coin
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!
Wiring adapter worked great, AFTER I re-pinned 2 out of 4 of the connections to line up with my 2022 Ford E-350 cutaway harness correctly.
