The Curt Echo under-dash is all about simple use and easy install. With the main unit mounted out of sight beneath the dash, all you need is your smartphone to control the settings on the brake controller. You won't have to worry about banging your knee on a bulky controller, cluttering up your dash, or ruining the sleek look of your interior.


Control Your Towing with Your Smartphone and an App

The Echo is unique for giving you control of your towing through your smartphone. You can set the maximum braking output, adjust the braking sensitivity, apply the manual override - all from the OneControl app.


The Echo connects to the app via Bluetooth. You can save multiple trailer profiles in the app, a big plus if you have a fleet and want to be able to just select a pre-set configuration and get towing. And don't worry: after you've downloaded the app, you don't need to have data on to use the app with the brake controller. You'll be able to receive calls and texts and access your other apps.


User-Friendly OneControl App

Simple, intuitive, and user-friendly, the OneControl App makes it wicked easy to manage your settings and control your trailer.


how does the One Control app work

1. Manual Override

This big orange button in the middle of the app is your manual override. Press and hold the button, and the brake controller will smoothly apply the trailer brakes without applying your vehicle's brakes. This is perfect for stopping sway or controlling your trailer's momentum in an emergency.


Curt Echo Under-Dash App Manual Override Button

Quick tip; Put manual override right at your fingertips by adding this button (C83HR - sold separately) to your dash. The app must be running for the button to work, but it can be in the background while you use other apps on your phone. The button has an adhesive pad for a quick-stick installation and includes an easily replaceable battery.


2. Brake Output Indicator

The outer ring gives you a visual indicator of how much power is being applied to the trailer brakes. This is determined by your max output setting.


3. Max Output

Braking output is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop.


To set your maximum braking output, tap this button and increase or decrease using the + and - buttons. You want to set the braking output as high as you can without locking up the brakes. Once you've set up the brake controller the first time, you shouldn't need to adjust the settings until the trailer load changes, you switch trailers, or road conditions change.


4. Sensitivity Level

This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the max output level. This is a great adjustment to make when you're towing a heavy load and the trailer will need more umph to bring it to a stop so it doesn't push your vehicle forward.


Just like max output, if you need to change your sensitivity level, use the + and - buttons. If your vehicle takes too long to come to a stop, increase the setting. If it stops too abruptly, lower the setting. You may also need to adjust the sensitivity based on your own preferences, or when the trailer load or road conditions change.


5. Vehicle Hazard Lights

If you turn on your vehicle's hazard lights, there's a chance the trailer brakes will pulse on and off as the lights flash. Turn this setting on any time you activate your hazard lights to prevent this problem.


Save Multiple Trailer Profiles

Curt Echo App saves multiple trailer profiles

Get on the road faster by saving your settings. With the app, you can add and store multiple profiles for both trailers and vehicles so that your preferred settings will be ready to go as soon as you hook up. This is perfect if you own a fleet and don't want to have to reset the controller every time you swap out trailers. You'll have the ideal settings saved and waiting for you. To switch between profiles, just swipe left or right.


OneControl: One-Stop App for Towing

If you like the idea of monitoring your trailer from your phone, the other OneControl systems could be a great fit for you.


The Curt True Course (C94VV - sold separately) is an advanced Bluetooth sway control system that automatically triggers the trailer brakes (independent of the vehicle's brakes and the brake controller) when it detects dangerous trailer movement. The Curt Tire Linc (C54VV - sold separately) Bluetooth TPMS monitors the temperature and pressure of your trailer tires. All of these systems use the OneControl app so you can manage all of them in the same place on your phone.


Simple, Out-of-the-Way Installation

You won't be dinging your knee on a bulky brake controller or interfering with your vehicle's lower airbags because the main unit mounts out of sight under your dash. This product comes with an adhesive pad and 4 zip ties to make it easy to mount anywhere. (Just don't zip-tie the box to wiring or cables that can shift as you drive!) Thanks to the 3-axis accelerometer, the main unit can be positioned at any angle. No matter how you install it, the unit will sense the direction of travel and deliver smooth, even braking.


Curt Echo Under-Dash Main Unit Module

The easiest way to install this brake controller is to get a custom, vehicle-specific adapter (sold separately) that plugs right into both your vehicle and the main unit - no hardwiring required. Otherwise you'll have to get a univeral harness and potentially splice into your wiring.


Note: If a custom brake control wiring adapter is not available for your vehicle, a 30-amp circuit breaker (sold separately) may be required for installation.


That done, download the OneControl app on your Apple or Android smartphone and wirelessly pair the unit to your phone via Bluetooth, following the in-app instructions. It should take about 5 seconds for them to pair. Once paired, the LED light on the unit will turn a solid blue. Plug in your trailer's 7-way and let the whole system calibrate for another 5 seconds. When the LED turns green, configure your desired trailer brake settings and save it as a profile. Then you're ready to tow!


Curt Echo Under-Dash LED Troubleshoot Cheat Sheet

Proportional Braking

What is proportional Braking

The Curt Echo under-dash brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.


The Echo under-dash uses an internal 3-axis accelerometer to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to ensure that your trailer slows at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In
part number: C51322

Install your Curt electric trailer brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in port beneath your vehicle's dash.

Features:

  • Plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller
  • No cutting or splicing required
    • Custom connector end plugs into the built-in port beneath the dash of your vehicle
    • Other end plugs into the back of your electric brake controller
  • Compatible with time-delayed and proportional brake controllers from Curt
    • Brake controller must have built-in plug for adapter to connect - will not work on controllers with pigtail wiring harnesses
  • 2' Long, 12-gauge wires have protective covering to deter damage
  • Limited 1-year warranty


Installation of Curt Brake Controller Adapter

To install your Curt electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


This adapter plugs into the port on your vehicle's built-in brake control wiring harness. For most applications, this harness is located beneath the dash, near the center console.


No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

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.



by: James 12/19/2023

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.

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.

They are the best at what they do. They found the parts I needed and got them to me the next day. I appreciate the dedication to their customers. This product worked for my 1997 Ford F350 with the factory-installed tow package.



by: Michael 04/05/2023

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.



by: Eric P. Foxboro,MA07/16/2017

Everything was as described. Easy easy installation in 10 minutes. Not the top of the line controller but it's all I need. Very fast shipping as well. Couldn't be more happy with etrailer. I will be purchasing my fifth through etrailer soon!



by: Matthew 11/25/2023

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!



by: Jesse 12/18/2023

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.

Very easy to install. Less than 15 minutes. On a 2023 GMC sierra 1500



by: Earl 08/21/2023

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.



by: Dave K / NHS08/28/2017

Great job came on time. Installed easily. Works great. Better still is the service from etrailer. New what I needed for my truck. Deserves repeat business

by: Stephen02/08/2024

This unit has a constant draw on the battery and will kill the battery flat in about three days if the vehicle sits. Numerous other users had the same issue. Don’t buy. I will be contacting Curt about this issue.

PERFECT. The etrailer.com employee (Roger R) that assisted me on my phone in order was fast, and efficient. He looked up my truck (2004 f250 diesel 4x4), and assisted me in ordering the exactly correct harness for my application. Plug and play. Thanks.

by: mike R.07/29/2013

Excellent. Perfect fit, exactly what was needed. Connected the Curt C51110 Brake control to factory wiring. Only thing that could make it better is if it came with someone to plug it in for me and save me 10 seconds.

The products worked great up until about a few weeks ago Thats when I sold the truck where the items were installed. lol. Really though, I very much liked how the products listed and purchased from etrailer.com were easy to find, fit exactly as described, and performed as needed. etrailer.com is always one of the first places I look when searching for items for my new truck.



by: Paul08/29/2022

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!



by: Chris10/03/2022

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



by: Scott09/18/2022

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.



by: Lawrence 02/07/2024

straight forward install, works as inte nded.



by: Chris 08/20/2022

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.



by: Stuart 03/27/2024

Exactly what I ordered and expected.

  • Will Curt Echo Under-Dash Brake Controller Work with Factory Tow Package on a 2022 Ram 1500 Rebel
  • The Curt Echo Under-Dash Wireless Brake Controller # C27JR and Wiring Adapter # C51458 will work great on your 2022 Ram 1500 Rebel since it has the factory tow package but no factory controller! I really like this controller since it's inside the cab so you don't have to remember to grab it prior to towing, but it's also out of the way and doesn't take up any space inside the cab.

  • Comparing Curt Echo C79DR and C27JR for 2019 Porsche Cayenne
  • That is correct, both the # C27JR and the # C79DR are the same Curt Echo with a slightly different design and connection/mounting position. Both use the Curt Echo app on your phone and are compatible with the manual override button # C83HR if you would prefer to have a physical button in the cab. They came out about the same time, choosing between the two comes down to your preference. The # C27JR mounts under your dash as you said and will also require the # C51515 wiring harness.

  • Brake Controller For A 2004 International 4300
  • Though The Curt Echo Under-Dash Wireless Brake Controller # C27JR will work with your 2004 International 4300. Before installing a brake controller you will have to find the 7 wire plug in the frame rail behind the cab which contains the wires for lights and signals. From there you will have to wire that into the wiring kit # ETBC7. You will have to cut off the 4-way on the ETBC7 and then use a circuit tester # PTW2992 so you can determine all the functions of the wires on your truck.

The Curt Echo installs behind the dash so there is no drilling into the vehicle nor do you have to worry about taking up leg room. It uses your mobile phone for setup.

  • Which Curt Echo is Better? The Inline or Under Dash
  • Hey Jon, so in theory the inline Echo Mobile part # C51180 and the under dash part # C27JR should perform the same but we have found that the under dash version works a lot better so it would be the way to go. Overall performance and connectivity just is more consistent. It's also not easy for a thief to potentially steal like the C51180. Which to install it in your 2023 Honda Ridgeline all you would need is the part # C51392 and you'd be set.
