No clunky box or knobs to deal with. The Curt Echo Under-Dash connects to your smartphone through Bluetooth, putting all your trailer brake settings right in your hand with the OneControl app. Adjust max output, fine-tune sensitivity, or hit the manual override right on-screen. The app also lets you store multiple trailer profiles so you can switch setups fast. Even if Bluetooth drops, the system keeps working with your most recent settings.
Instead of a bulky controller taking up legroom, this unit tucks neatly behind the dash. The small main box—just 3-3/8" long x 3" wide x 7/8" thick—mounts out of sight using an adhesive pad or zip ties. No drilling or cutting trim panels. You keep a clean factory look with nothing to bump your knees on.
The Echo’s proportional control makes towing feel natural. Its internal 3-axis accelerometer senses how hard you brake and sends matching power to the trailer brakes. Hard stops get full braking force; light stops are gentle and smooth. It works with 1 to 4 axles and supports electric trailer brakes for consistent control.
Hookup is simple thanks to the custom-fit harness that plugs directly into the factory port under the dash. Once connected, pair your phone via Bluetooth—usually in about five seconds—and you’re ready to calibrate and tow. The LED indicators show status and make setup easy without special tools or wiring skills.
Reverse polarity and short circuit protection guard against wiring mistakes, while diagnostic LEDs give quick feedback if something’s off. A limited lifetime warranty on the controller and a 1-year warranty on the harness back it up for the long haul.

Ratings & Reviews
The products are excellent and the installation instructions are very easy to follow. Products are very well made
The combo of the Curt Spectrum brake controller and wiring harness made installation a snap
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.
We got a new truck and needed to convert our trailer breaking unit to the new truck. I wrote to be sure what I needed, got an answer right away, ordered it, and it was easily installed!
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. $[XX] later and this controller removed, I've not had any problems with the battery
Easy plug and play. Would buy again.
This brake controller has to be unplugged when not in use or it drains the battery in a few days. I had to have a electrical test done in my vehicle ($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.
Easy hook up to the OEM plug
This is used on a 2020 Chevy Silverado 1500 pulling a 16' enclosed cargo trailer. With the appropriate adaptor cable it was very easy to install, just plug in and mount in a convenient spot. Once installed it was simple to get it matched to the weight and brake setup of the trailer. Close to 6k miles with it so far & very happy.
The wiring adapters worked great. It made installation quick, easy, and clean.
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.
Just what I needed to move my brake controller to my new truck. Best price that I found.
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!
Works Great. Very satisfied
Was put in the mailbox.still waiting on item number 2
