Most brake controllers hang down under the dash where they hit your knees or clash with modern interiors. This one mounts completely out of sight, just a small box tucked up under the dash so nothing sticks out. The main unit is only 3-3/8" long x 3" wide x 7/8" thick, leaving your cab clean and uncluttered. Mount it at any angle using the included adhesive pad or zip ties—the internal 3-axis accelerometer automatically senses direction for proper operation.
Hard-wiring a controller can mean splicing and chasing wires. Here, the custom harness plugs directly into your factory brake control port, so installation takes only minutes. No cutting required, just plug one end into your truck’s existing connector and the other into the Echo unit. It’s also easy to move between tow rigs or trailers since you can simply unplug and go.
The Echo’s proportional system uses an internal 3-axis accelerometer to match trailer braking to how you actually brake. Press lightly on the pedal and the trailer eases in; stomp hard and it responds instantly. It works with electric trailer brakes on trailers with 1 to 4 axles (8 brake assemblies). The result is steady, confident stops that reduce wear on tires and pads.
This controller connects over Bluetooth so you manage everything from your smartphone. Through the OneControl app, you can set max output, adjust sensitivity, apply manual override, and watch a live brake output indicator. The app saves multiple trailer profiles—a big plus if you tow more than one trailer—so your favorite settings are ready next time. Even if Bluetooth drops out, it continues braking safely using your last saved settings.
Troubleshooting is simple with diagnostic LEDs on the main unit showing status at a glance. Built-in reverse polarity and short-circuit protection guard your wiring from damage. Once paired and calibrated, just drive normally—the system handles smooth braking behind the scenes for every trip.

This fit my 2019 Honda Pilot perfect. Plugged right in under the dash. The plug branches out of another wiring harness directly above your OBD plug in. On the left side of dash. You will have to lay down and get your head near the pedals to see it tucked up in there. Very easy install, glad I went with etrailer. Made it simple.
Don’t even know it’s there, set it and forget it.
Worked great I installed my brake controller in new truck in no time. On line instructions were great workout perfect.
Delivered faster than advertised. Took me much, much longer to FIND the Ridgelines connector. Once I going that, it took about 25 minutes to put on and secure the wires
Everything about the buying experience has been great! I was impressed with the email communication and the actual phone call to let me know that my ordered had been shipped out. I will be using the etrailer.com website again to make purchases for my trailer and camper accessories! Thanks!
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. $[XX] later and this controller removed, I've not had any problems with the battery
Very pleased with the ease of install and how it functions.
This brake controller has to be unplugged when not in use or it drains the battery in a few days. I had to have a electrical test done in my vehicle ($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!
This part is listed to fit a 2019 Honda Pilot. I needed one for a 2019 Honda Passport;(basically the same vehicle); however since the Passports just came out in about February no one could tell me if it would work on the Passport. So I took a gamble and ordered this wire. Well I can confirm that this part does work on the 2019 Honda Passport. The hardest part was reaching the plug under the dash and getting this wire to plug into it, all without any room and only being able to get one hand up under dash. Wire made hooking up brake controller a lot easier than direct wiring.
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.
Just finished the install. It was nice to be assured that I had everything I needed to finish the job before I got started. Honda didn't make it easy.
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.
Could not have been easier on Honda Rid geline
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!
I had no clue what I needed but the customer service team helped me out. Easy install and works great.
Was looking for a trailer break for a 2021 Honda Passport. My vehicle didn't have a hitch so I installed an etrailer hitch and later, a 7-way plug (also from etrailer) just in case I bought a camper. Now I'm purchasing a camper so needed a break. My experience with emailing and then "live chat" came up dry as far as a plug and play option for my Honda. I checked my vehicle and it did have a 4-pin under the dash so I thought this strange. I decided to call and ended up speaking with Fred who took the time to think through how to make it work. As disappointed as I was in my interaction with emailing and Live Chat, I was thrilled with Fred's support. The parts came quickly (as usual with etrailer) and the install was a breeze. Thank you Fred!
The Curt Custom Wiring Adapter for the 2017 Honda Ridgeline worked perfectly for the installation of my new Curt Spectrum Trailer Brake Controller. Thanks etrailer!Thanks Curt!
