  • Tire Linc (C54VV - sold separately) monitors tire pressure and temperatue

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.


The Curt Echo under-dash is all about convenience. 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.


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.


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 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 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.


Plug-and-Play Installation

You won't be banging 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 included custom-fit adapter plugs into the port on your vehicle's built-in brake control wiring harness, which you'll find underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. Once you're plugged into your factory port, just plug the other end of the adapter into the Echo. No hardwiring needed!


Once that's 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

Note: If you don't already have a 7-way plug at the back of your vehicle, take a look at our exclusive 7- and 4-way brake controller installation kit (ETBC7 - sold separately).


What is Proportional Braking?

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 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.

Very pleased with the ease of install and how it functions.

Although this seems like a great idea, the controller app from Curt/Lippert only works on a very recent cell phone or on an Android-based car stereo head unit. There are no factory Android car stereos available or aftermarket Android head units from the major players such as Pioneer, JVC, Kenwood, Alpine. The app is not Apple Car Kit or Android Auto enabled. This basically means you need to play with your cell phone while driving to adjust the brake controller. Even touching your phone while driving is illegal in many, many states. It really doesn't matter how good or bad the brake controller is if you can't use it. The same app is used for other Curt/Lippert Bluetooth Echo brake controllers and for their anti-sway controller and trailer tire pressure monitors. One has to wonder why this is even available for sale. I plan to simply avoid all Curt/Lippert Bluetooth trailer equipment in the future.

Works Great. Very satisfied

Great service! Thanks Zach!

I have to say, the unit works pretty well... Took some adjusting at first and sometimes have to still make small adjustments when the trailer brakes grab a little to much while coming to a stop. Easy installation and setup and does the job.



by: Larry03/21/2026

Hard to tell. For my 2018 Armada the power input and output was not reaching the controller properly. I took it to a shop that installs Curt products. They added a diode to one of the wires. They told me some vehicles need it some don’t. When the controller was in my Ram, it didn’t. After hours of diagnosis, they strongly believe my vehicle has a wiring problem. In the end I ended up getting the Curt Echo which works. A lot cheaper than going to the dealer to figure out wiring issues.

Easy installation and product works exactly as it should.

I installed the Curt C51110 controller with the Plug & Play C51382 into my 2016 Frontier, works perfectly.

ITS BEEN A YEAR SINCE INSTALLATION, ITS BEEN IN THE SAME LOCATION, HAVENT HAD ANY PROBLEMS! GREAT PRODUCT, GREAT PRICE!



by: Timothy04/22/2021

I've had the brake controller in use for over a year in my 2012 Nissan Frontier. The install was easy and took about an hour. My truck is a 2WD model so I mounted the controller in the plug that is used to select between 2WD and 4WD on vehicles equipped with 4WD. So the install look like factory.

As always, the etrailer staff came through with the right part for my Nissan.

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 perfectly



by: Alan03/12/2024

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: Laura10/29/2024

the black side went into curt triflex excellently. the white side was supposed to be wired for my nissan, just clip in & done. but the wires were not the same and in the wrong sockets of the clip. my electrical man is currently working this out. HOPEFULLY.



by: Caleb08/06/2025

Perfect fit and was exactly what it said it was



by: Brian C06/07/2016

So much easier than cutting wires and crimping butt splices. Plus it make un-installation easier and doesn't void the warranty for the brake controller. the time saved was worth the money for me.

One year later and unlike my guitar hero drum kit the insulation on the wires has not cracked and fallen off yet. Plus its nice to be able to unplug the unit from the car.

  • Wiring Brake Controller to Under Dash Wiring of 2021 Ford Ranger
    We had the chance to install a brake controller in a similar Ranger as your 2021 model and when using standard brake controller wiring like with the # C51515 to install the Curt Echo Mobile # C27JR the yellow/orange goes to the black wire, the blue wire is going to go to the blue wire, the white wire is going to go to the white wire, and the violet with white stripe goes to the red wire.

  • Location of Brake Controller Port on 2023 Jeep Grand Cherokee 4xe
    Hi Robert; it looks like your 2023 Jeep Grand Cherokee 4xe doesn't have a brake controller port since you don't have the tow package. This means hard wiring the # C27JR is your only option for installation. If have a plug and play wiring harness I would return it to whoever you bought it from.

    Hey Arek, so it looks like Curt is the only brand of Bluetooth brake controllers but they do have two different types. They have the super popular Curt Echo Wireless Brake Controller # C51180 which just plugs into a 7-way and is controlled via the app, or the Curt Echo Under-Dash Bluetooth Brake Controller w/ OneControl # C27JR with the adapter # C51515.

    Hello Dan, thanks for reaching out. The best way to add a 7-way and brake controller to your 2017 Hyundai Santa Fe with an aftermarket 4-pin is by using the Universal Installation Kit # ETBC7. This kit contains everything you need to upgrade the 4-flat to a 7-way, including all of the necessary wires for a brake controller.

  • Best Way to Find Brake Settings for Echo Under-Dash Controller on a Volvo XC90
    The standard Curt Echo # C51180 does use the same technology as the Curt Echo Under-Dash # C27JR, but whenever I've heard about the pairing issue being a problem it causes settings to become erratic rather than just being a struggle to find the correct setting.

  • Easiest Plug and Play Brake Controller For a 2024 Jeep Grand Cherokee
    The Curt Echo Under-Dash Bluetooth Brake Controller # C27JR will provide you with one of the easiest installations as the Pigtail # C51446 will connect it to your factory wiring. And unlike other controllers there is no dash mounted controller or knob so everything simply gets secured under your dash. Then you will control the settings for it with your smart phone using the OneControl app.

  • Curt Echo Says Trailer 7-Way Disconnected But it Isn't
    Generally when the Curt Echo Under-Dash # C27JR says the 7-way is disconnected but it isn't, the issue is actually the 7-way is problematic, either on your vehicle or trailer. I'd check to make sure the 7-way on both does not have bent pins, or corroded or damaged in some way.

The "play" part kind of depends on what your 2018 Toyota Tundra is equipped with. If you have the factory 7-Way then you're good to go.

If you wanted the absolute easiest install that literally takes seconds go with the Echo Mobile as it just plugs into an active 7-way. That's it's biggest strength.

You may be able to resolve your issues by checking to see what other circuits are drawing power from your 7-way and disconnecting those that are not necessary.

    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.

  • Troubleshooting 7-Way Trailer Connection Wiring on 2017 Nissan Frontier
    In your 2017 Nissan Frontier, the Curt brake controller should be installed using the custom wiring adapter # C51382. This should work correctly to give you the proper wiring within your cab. Then you will use the Curt # C56226 or the Tekonsha # 118266 to get the correct 7-way. If you have done this even using the previous relays, check your trailer connection for functions using the attached photo and a circuit tester like # PTW2993. It sounds like the trailer may be mis-wired and...

    Hey Dirk, the correct Curt brake controller install harness for your 2025 Nissan Pathfinder is the part # C51382. I confirmed this with Curt just now. There actually isn't a part number C51383. Do you have a Curt brake controller already?

  • Recommended Plug and Play Brake Controller Adapter for a 2022 Nissan Pathfinder
    No, I am sorry we do not because Tekonsha did not make one for your 2022 Nissan Pathfinder. The Prodigy P3 Brake Controller item # 90195 includes a universal harness you can use but you'll need to cut and splice wires. Curt does have a plug in play adapter but it only works with their brake controllers. It is the Curt Custom Wiring Adapter for Trailer Brake Controllers item # C51382. It will allow you to easily install the Curt Spectrum Trailer Brake Controller item # C51170.

  • Install Harness for Tekonsha Brake Controller 2025 Nissan Pathfinder
    Hey Tom, for your Tekonsha brake controller to install in your 2025 Nisssan Pathfinder you would want the install harness part # C51382 which plugs into the port under your dash. You would need to cut off the Curt side of the connector and wire it by color to the Tekonsha universal harness since we don't have a Tekonsha harness that fits your vehicle at this time.

  • Does Curt Spectrum Come With Cable for Plug and Play Installation on 2024 Nissan Pathfinder
    Hi Steve; the Curt Spectrum Brake Controller # C99GV does include the Curt Custom Wiring Adapter # C51382. We changed how these are listed so it is all under one part. The wiring harness is in the pictures but can be easily overlooked if you aren't familiar with what it looks like.

  • Brake Controller Recommendation for 2013 Nissan Frontier with Tow Package
    For a basic but great brake controller the Brake EVN # TK63VR would work well in your 2013 Nissan Frontier. It would install to the factory wiring of your vehicle with the part # 3050-P which plugs in under the dash. It comes with hardware to easily attach to the console as well. For a brake controller with an even smaller foot print that installs with just a small knob on the dash of the vehicle the Redarc Tow Pro Liberty part # RED24FR would be a great option that would install with...

  • Part Needed to Add 7-Way to 2011 Nissan Pathfinder
    To add a 7-way to your 2011 Nissan Pathfinder, all you need to do is add the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # C56226. This will replace your 4-way and give you the 7-way you need to tow your camper with electric brakes. You'll then be able to use a brake controller like the Curt TriFlex NEXT # C24VV with Wiring Adapter # C51382.

  • How Can I Tell if My 2013 Nissan Pathfinder Came With Factory Tow Package
    All 2013 Nissan Pathfinders came pre-wired for a tow package, so we know your Pathfinder at least has something. If your Pathfinder came with the tow package option from the dealer, then you would have a trailer hitch and trailer wiring at the back of the Pathfinder. Since you are asking for a wiring kit, I'm guessing you need the wiring still. For this I recommend the Curt 7-Way Wiring Harness, # C56357, if you want a 7-pin trailer connector or the Curt 4-Way Wiring Harness, # C56281,...

  • Troubleshooting Brake Controller that Says Not Connected to Trailer
    Since your trailer's brakes worked on another truck that would indicate that the problem is on the truck side of the equation. First and easiest thing to check is to check for corrosion on your truck's 7-way. Some fine grit sandpaper can easily remove any corrosion that would prevent the connetion from being made. Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide....

  • Recommendation Between the Prodigy P3 and Curt Spectrum Brake Controllers for a 2008 Infiniti QX56
    Both the Tekonsha Prodigy P3 # 90195 with the Adapter # 3050-P and the Curt Spectrum # C51170 with the Adapter # C51382 are excellent brake controllers and I wouldn't hesitate to recommend either one for you to use with your 2008 Infiniti QX56. Even though they are both electric brake controllers the P3 is more of a traditional controller while the Spectrum is a new style of brake controller. Ultimately I recommend going with the Spectrum over the P3 because you can install it just about...

  • How to Set a 2012 Nissan Frontier Up for Towing a Trailer with Brakes
    You are correct in that you will need to use a brake controller in order to operate the brakes on a trailer. The Curt Venturer Trailer Brake Controller part # C74VV is a fit for your 2012 Nissan Frontier and will not require any splicing so long as you also use the Curt Custom Wiring Adapter part # C51382. The relays and jumper harness that you are referring to are not included with the brake controller and will need to be purchased separately. If your Frontier came with a factory 7-way...

  • Problems With Curt Echo And Brake Controller Recommendation For A 2022 Nissan Pathfinder Platinum
    Hello Hugues, thanks for reaching out. Generally, with the Curt Echo wireless controller, the error codes it throws are pretty accurate. A bit of play at the trailer connector could explain the intermittent issues you are having. Since the trailer is brand new it is hard to believe that a wiring issue would be the cause, unless it came off the lot that way. Sometimes the contacts in the vehicle trailer connector can become loose- same on the trailer side. The only real way to fix this would...

  • Recommended 7-Way and Brake Controller for a 2019 Nissan Frontier
    The wiring that I recommend installing on your 2019 Nissan Frontier so that you have a fully functioning 7-Way is the Tekonsha T-One # 118266 because it is the most reliable option available. This comes with the wiring and relays needed for the installation but you may be interested in the mounting brackets # PK12711U and # C57202 as well to easily mount the 7-Way. If you don't already have a brake controller then I recommend going with the Curt Spectrum # C51170 because it is a proportional...

  • Troubleshooting 2018 Nissan Frontier SV with Brakes that Lock Up when Key is Turned On
    The brake controller and the brake controller wiring you mentioned does not affect the 12 volt accessory circuit of the 7-way that you are wanting to use to charge your trailer battery. Now with that said if your trailer brakes are locking up as soon as the ignition comes on that to me indicates that you have the brake output and the 12 volt accessory circuits either wired backwards (most likely) or there's a short between the two circuits. The 12 volt accessory circuit should be in the...
