Quick Tip: The Bluetooth PIN for initially pairing to your smart device is located in the quick reference guide!

Note: If Bluetooth connection is lost, the brake controller will continue to function safely, using the most recently programmed settings. This brake controller is not compatible, but will not interfere, with Apple CarPlay or Android Auto.

One-Step Installation

The Curt Echo is unique for its plug-and-play installation. With no wiring or permanent installation, setting up the Echo is a breeze.

Curt Echo Wireless Brake Controller Installation

The main unit plugs into the 7-way at the rear of your vehicle and then the 7-way trailer connector plugs into it. Use the included strap, found inside the cap, to secure the Echo in place. It will help ensure a constant connection between vehicle and trailer.

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 in the app and save it as a profile. Then you're ready to tow!

Note: If you don't already have a 7-way plug at the back of your vehicle, check out our exclusive 7-way upgrade kit for brake controller installation (ETBC7L - sold separately).

Towing with Your Smartphone and an App

Besides the crazy-easy installation, 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.

Completely wireless, the Echo connects to the app via Bluetooth. You can save multiple towing 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.

OneControl App

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

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.

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 back and runs on a 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.

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 trucks, trailers, or drivers. 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.

LED Status Indicator

The LED indicator light on the top of the plug-in module will show you when the brake controller is connected. You can also check the LED for simple diagnostics when you need to troubleshoot.

Weatherproof Construction

Because the Echo mounts outside the vehicle, it's designed for maximum weather resistance. The unit is filled with an epoxy resin that seals off the internal components from moisture and the elements. The Echo also has a soft locking tab for connecting to your 7-way plug that reduces vibration and helps ensure a constant connection.

What is Proportional Braking?

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 hard; 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 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.

Works amazingly well after the brief learning curve. You just can’t over think the process and do it. What a difference not having to install a brake controller on a new vehicle. I would buy it again.

Still working nicely after cleaning all contact parts for best connection. Hope to use it for many seasons.

by: Vickie02/14/2024

Customer service response is prompt. Order arrived quickly. I’ve attached, synced, and tested the controller on my 2020 Tacoma, pulling my 16ft travel trailer. Lights and app indicate it is working. I’m still testing adjustments, as I’ve never used a brake controller. I saw some reviews that complained about brake pulsing at low speeds. I have NOT experienced this problem. Manual actuation works well at low speed. Information says app must run in the foreground. I’m trying to determine what that means. Can I open the app and switch to another app, or does the app need to stay on constant display?

Brooke M.

2/26/2024

Yes! The app should be the one on constant display on your phone screen; the one you are viewing. It looks like the reason is if its running in the background, if you have a different app on display while towing, it can cause delays in breaking times. Best to be safe and just run the OneControl Auto app when towing.

Happy after using controller for a year. Tends to lose Bluetooth connection a lot, but the controller continues to work on previous settings, so that’s not a problem. After a few tweaks, I didn’t need to change anything. Each time I connect it for a trip, it defaults to my last setting.

Kate F.

2/16/2025

@Vickie Glad you were able to tweak it just where you need it! I have heard the issues with the bluetooth, it is something they are trying to make better. What is your favorite trip that you have used the Curt Echo on? I'm always looking for a new spot to explore, and there is no one better to ask than our customers =)

Curt echo wireless brake controller could not be setup to work properly, on the lowest settings no brakes at all , next step up brakes would grab and lock up.

Trailer brakes working perfectly with a factory in dash brake controller. Would like to return.

Hey Norman. Most of the time when you are using an aftermarket controller when your truck has a factory controller, they start to argue with one another in away. You will need to take your truck to your Dealer and have them reprogram the truck to disconnect the factory brake controller.

Norm.

Tested trailer on a truck with factory installed electric brake controller. Then on truck with no brake controller. Trailer is good. Curt bluetooth brake controller, not so much, would like to return.

@Norm I'll get return information sent to you via email. It should show up in your inbox in the next few hours.

by: David03/01/2025

I bought a 2021 Tahoe High Country that was built during Covid. Little did I know that it was missing critical chips and parts that would normally be standard equipment. Consequently I found that the trailer wiring that is normally installed under the dash was missing! Luckily, the 7 wire plug receiver had the minimum 4 wires connected that makes this product work. It was simple to install and program. A lifesaver for me, as I pull a tandem trailer and need the braking. ( P.S. don’t buy a Covid Era vehicle!)

Gwendolyn Y.

Hey David. I'm glad that the install was still easy and simple! What are you hauling?

by: Barry04/09/2025

The controller works great. Installed brakes on a prior non-braked trailer. Also, the 51180 docs say it is compatible with all three of my vehicles. Can't beat one controller for three vehicles, and the controller can be set up to memorize various vehicle/trailer options. Really plug and play.

by: Randal 01/07/2024 One Year Later

Well I got this unit for my 40' motorcoach. Unfortunately it doesn't stay connected on my phone through the app inside the coach. But once you open the app and correctly set the app with your settings for the trailer or whatever you're towing it does a great job. So that's why it only got 4 stars. At least I didn't have to wire my whole coach, what a pain that would've been.

Randal One Year Later

So far the unit is performing good. Just be sure each time you hook up open the app so it is active on your phone. Im so thankful I didnt have to run all the wires for a internal brake control.

by: Rodney 01/02/2024 One Year Later

This controller was recommended to me by my Aluma Trailer supplier. It works well. Very happy I followed his advice. Since I use it with the save truck and towed vehicle, I don't even need to worry about my phone battery going down.

by: michael 02/19/2025 One Year Later

1 year of using this controller and still very happy with it. No problems with the control app on my android phone and it works great. Pulled our camper with it 6 or 7 times and never had issues getting it synced with the app and trailer brakes have activated properly for every stop.

by: Andrew03/14/2025 One Year Later

Works well and have had no issues with function. You do need to keep the app up and open to use. Adjusting was easy and initial setup was literally plug and go in 5 minutes. No issues disconnecting while driving as I read in other reviews. I like that it's one controller I can use for multiple vehicle and trailer combinations.

For use on multiple vehicles that do not have built in brake controllers. Or for just one vehicle without a brake controller, this device is super. I have been buying vehicles over the years that come with brake controllers integrated in them. But I just purchased a 2025 Tahoe and 2025 Wrangler. Both had receiver hitches and 7 pin plugs. The problem was neither vehicles had brake controllers. Problem solved. Curt is a brand you can trust. I have owned several of their other products so I know they have a great reputation.

by: George04/15/2025

I think the most important thing for someone who is installing the 7 way plug is that the blue wire is not required. Please stress this fact. I spent several days trying to get a definitive answer on this issue.

by: C12/31/2024 One Year Later

I still do not like that you need to have Location Services for a Brake Controller.

Fix this.

The other thing I noticed is that it has a tendency to grab hard when pressing the brake, no matter what setting I have it on on the iPad I am using.

Other than that it's ok, but still gets only 1 star for the utter ridiculous need for Location Services to be on. I'm quite frankly tired of the invasive nature of most modern tech.

by: Radu08/18/2023

Installation and pairing with my mobile phone Android ver 9 was straightforward I want to try also with my other phone version 5 Android that has bluetooth even the manufacturer not recommends. I drove my trainer RV for about 500 miles and did some adjustments while driving to feel the trailer brakes engaged. So far this device is expectedly very good and see very easy on phone the trailer brakes are engaged. I don't see why it comes with manual braking when click that red button on phone screen, because when you do car's brakes the app on the phone does the same thing on trailer's brakes, I secured the device with that rubber band and my trailer connector with a Velcro band wrapped a fee times. I am happy with the purchase.

Toyota Echo

I have been using the Curt Echo wireless brake controller for about a year now and it has performed flawlessly. My only dislike is that if you open or use another app on the phone running the trailer brake app, you have to re-establish the Bluetooth connection in order to operate the brakes manually. I have never had to use the manual brake operation and my trailer is so small that it won't likely be an issue, but if you are towing a larger tailer that could experience sway, then you would want a separate device to run the brake app exclusively (an old phone for example, you won't need cell service).

by: Nick 09/08/2023 One Year Later

This device makes it in every easy to control the brakes on your camper. I considered installing a typical under dash style, but this option is a once and done purchase for all my future 7-pin trailer brake controlling needs. It connects effortlessly to my phone via bluetooth. There are multiple profiles in the app for different vehicle/trailer combinations. So simple.

After about two years of use this controller is still super simple and effective. I dont even need to go into the app since it remmbers the previous settings on the device. Essentially flawless.

2025 Volvo XC90

Works exceptionally well with my XC90 T8 plug in hybrid. It allows the regenerative braking to slow the vehicle without applying the trailer brakes until more braking is required. As soon as the braking exceeds the regenerative braking, the trailer begins to assist.

It worked very well, The vehicle didn't feel like it was being pushed by the trailer, when stopping going downhill. We were in south west PA.

Comparing the Universal Installation Kit # ETBC7 and the 7-Way RV Upgrade Kit # ETBC7L
There are a few differences between the Universal Installation Kit part # ETBC7 and the 7-Way RV Upgrade Kit part # ETBC7L. The biggest one is that part # ETBC7 comes with both the power and brake output wire you will need to run to the cab/battery whereas the part # ETBC7L only comes with the power wire you will need to run to the battery. The reason for this is because part # ETBC7L is geared more towards wireless brake controllers like the Curt Echo Mobile Trailer Brake Controller part...

The Curt Echo brake controller # C51180 is a fit for your 2020 Ford Ranger with a 7-way and does not require any additional components to install or function.

4-Way to 7-Way Adapter Recommendation for Installing Curt Echo Brake Controller
If your plan was to install a brake controller you'd have to also run the black wire of the 7-Way Adapter part # 30717 to the to the positive post of your vehicle battery as well as the ground you mentioned.

Is Truck Brake Controller Wire Needed With Curt Echo Brake Controller on Truck With Air Brakes
The blue brake wire that is normally required to connect to a 7-way for use with a brake controller is not needed for use with the Curt Echo Wireless Trailer Brake Controller # C51180.

Can I Use a 4 Way Vehicle Connector with 7 Way Adapter and the Curt Echo Brake Controller?
It sounds like you may already have a 4 way connector on your vehicle, which is half of the battle. In order to operate the Curt Echo Mobile Wireless Brake Controller # C51180 you will need an almost fully functional 7 way connector; using something like the Hopkins # 37185 adapter from the answer you were looking at would work, but it doesn't come with all of the wiring you'll need so I don't recommend using that and you will need to run a power wire to your battery (not included). Instead,...

We definitely have what you need to equip your 2020 Hyundai Palisade with a 7-Way connector, however there isn't a single part number available for this vehicle to accomplish this.
