Simple, One-Step Installation

Curt Echo Wireless Brake Controller Installation

The Curt Echo is unique for its plug-and-play installation. With no wiring, modules, or knobs to install, setting up the Echo is a breeze. Just download the ECHO Smart Control app on your Apple or Android smart device and follow the in-app instructions. The brake controller unit plugs into the 7-way at the rear of your vehicle and provides a port for plugging in your 7-way trailer connector. There's also an included strap, found inside the cap, that you can use to secure the Echo to your vehicle. When all the connections are made, wirelessly pair the unit to your phone via Bluetooth. Once paired, configure your desired trailer brake settings in the user-friendly app.

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

Echo Operation

Curt Echo App

The Curt Echo brake controller is managed entirely from the free ECHO Smart Control app on your smartphone. It connects via Bluetooth. From the simple, user-friendly app you can set the maximum braking output, adjust the braking sensitivity, and even apply the manual override. 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 profile and tow. 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.

Braking Output and Sensitivity

Curt Echo App Braking Output and Sensitivity

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, select a level on the main screen of the app, going up to 100. 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.

You can also set the sensitivity, between 1 and 9, to control the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the set 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. 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.

Manual Override

Curt Echo App Manual Override

The app also includes a manual override button. Press the big orange button in the middle of the screen to slowly and smoothly apply the trailer brakes without applying your vehicle's brakes. This is perfect for stopping sway or limiting your trailer's movement while you're cruising. The maximum amount of power that will be applied to your trailer's brakes is determined by the set braking output.

Curt Echo App Manual Override Button

You can also add a manual override button (C83HR - sold separately) to your dash so you can use the manual override without the app. The app must be running - either open or in the background - for the button to work. The button has an adhesive pad for a quick-stick installation and includes an easily replaceable battery.

Save Multiple Trailer Profiles

Curt Echo App Mutiple 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 braking output, sensitivity, and display preferences will be ready to go as soon as you hook up. This is perfect if you own a landscaping business and you don't want to have to reset the controller every time you swap out trucks or trailers. But it's also really convenient to have at home. Because you can use the Echo on any car that has a 7-way, you and your spouse can trade off towing the family camper without having to completely redo the settings each time. You'll have the ideal settings waiting for you.

Dark Mode for Night-Time Towing

Curt Echo App Dark Mode

The ECHO Smart Control app has an included dark mode for driving at night. This will change your background from white to black to cut down on glare and make the app safe and comfortable to use.

Weatherproof Construction

Curt Echo is weatherproof

Because the Echo is made to be 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, ensuring long-lasting operation despite rain, snow, dirt, mud, and more. The Echo also has a soft locking tab for connecting to your 7-way RV-style plug that helps to reduce vibration and improve connectivity.

LED Status Indicator

Curt Echo LED Troubleshoot Cheat Sheet

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 indicators for diagnostics when you need to troubleshoot.

Proportional Braking

What is proportional Braking

The Curt Echo 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 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.

Average Customer Rating:  4.5 out of 5 stars   (1190 Customer Reviews)

Bluetooth-enabled brake controller lets you monitor and control all your braking activity directly from your phone. User-friendly mobile app saves multiple trailer profiles, and the compact unit plugs in line with your 7-way trailer connector.

2022 Ford Bronco

Picked up my teardrop in ABQ on 2/17/23, and the Echo was easy to mount and sync to my phone, and worked flawlessly the 175 mile trip home. I also got my longer 3-way curt ball mount from etrailer, and it is a beast and also worked perfectly!


As long as you follow the directions for hooking it up precisely, it works marvelously. Especially, if like us, no OEM brake controller was available for our Jeep Grand Cherokee.

I give it a low rating, however, because it is made very cheaply. Just from regular use (plugging it in and unplugging it), the unit cracked, and then after 1-2 more uses it completely fell apart. See the pictures.

I wanted to let you know that the controller does have a 1 year warranty and I have sent the warranty return instructions in a separate email to you.
-- Etrailer Expert Jenny N - 11/17/2022


I just received the wireless brake controller so my experience using it is still little, however it was very easy to setup. It took about 2 minutes to plug in and get setup once the app was installed on my phone. I pulled my trailer around the block and worked to setup the sensitivity and it seems to work flawlessly. I like how I can setup multiple profiles for my different trailers. I lease my truck to it is nice that I don't have to install wiring and install the controller onto the dash of the truck knowing I will most likely turn it in at the end of the lease

I have had the wireless brake controller for about a year now, and I have to say it has worked flawlessly. It connects to my phone each time without fail also. It is a bit more expensive than a wired controller but in my opinion, the ease of use and ability to use in different vehicles makes it well worth the investment.
Dana - 02/06/2023


Initially wouldn’t connect to iPhone but after uninstall/reinstall of app it was fine. After literally traveling around the entire US I have to say it was a blessing with plug-and-play simplicity and total control over braking parameters. The phone lost Bluetooth connection a few times while traveling but the controller maintains the program so no big deal. For me it was nice to see the braking rate on the phone graphic. GREAT PRODUCT! 5 stars!


Recently had a tow package installed on a 2022 Jeep Grand Cherokee L. Unfortunately, there is an issue with this model not allowing a computer flash. All lights work but no power to the brake pole on 7-pin. This little adapter solved all my issues bypassing the brake pole and using the brake lights for power. Less than 5mins of setting app up and adjusting brakes. Plug and play, no worry of warranty issues. Etrailer/Curt were very helpful.


I like the fact that I have a proportional brake controller I can stick in my glove box. It doesn’t have to be hardwired to the vehicle which is nice because I can use it on different applications. This one is definitely a plus over time delay brake controllers.

2022 Nissan Frontier

When this arrived I opened the box and did not have any packing material to cushion the contents inside to prevent damage. The right side of the controller was cracked open (screw missing) and one of the pins inside is bent. I was able to repair the damage on the side. Have not plugged it in to see if it works.

Thank you for letting us know! Customer service will be in touch with you.

I used the wiring harness and 7/4 pin receiver from etrailer to wire my 2021 Toyota Highlander to use the Curt Echo. It worked flawlessly the first time. So far I haven’t needed to make adjustments from the original settings for my R-Pod 180 travel trailer. I do wish there were better instructions for initial set up.

2014 Cadillac SRX

I received an open box/returned item. Very disappointed that etrailer would send this to me, especially since it cost $XXX. What I received was the item thrown into a brown shipping envelope with a brochure and the PIN. I have already contacted eTrailer. I hope they do the right thing.

I can understand your disappointment with receiving the brake controller this way. I can see that Customer Service has been working with you towards a resolution.

2004 Mercedes-Benz Sprinter

So convenient! I’m so glad our mechanic found this for us.

He was going to have to a lot of wiring to get our RV brakes to work from our 2004 Sprinter.

The wireless brake controller is a snap to use and saves a lot of money on repair bill.

The only problem I ran into was that the rubber strap that came with it came apart right a way

I used a velcro strap instead


I have used this controller to travel cross country, even in inclement conditions. It has one crack in the housting, but it works great. I also like the phone app.

Still awesome
James - 03/23/2022


Like many, I have an SUV that isn't wired for a brake controller and was nervous about whether a wireless controller would really work. The reviews pointed me toward the Curt Echo, but who knows if it would "really work". I've had it a year now and it's performed flawlessly. As a new trailer owner, it's one less thing to worry about. Now I just have to remember to close all the windows and lock the doors.

Toyota Echo

Added bonus, I can test my brakes on trailer without hooking up my car. Attach the echo, make sure battery on trailer is juiced a bit, start the app on phone. I Jack up the sides and test everything while repacking my berings. Love this device.

Great, it does what it says it would do
Robert - 03/07/2023

Toyota Echo

I purchased the Echo Controller after realizing my RV was not wired for Trailer Brakes and I needed to pull a trailer within days and no time to wire it myself or get it wired. I called eTrailer and explained my situation the solution that was suggested was the ECHO, I asked a lot of questions as I wasn't totally sold but was assured it would work and in fact it did. The only issue I have had is at times the Bluetooth does not stay connected, as indicated the ECHO defaults to the previous setting. I would buy it again.

2018 Toyota Echo

This is my second Curt Echo Wireless Trailer brake controller for my popup camper and it works great. Even better is the customer service her at etrailer. I had an issue with my billing and it was cleared up immediately.

the Curt wireless brake controller is working flawlessly. I appreciate the extra security strap that the newer model has and I would buy it again if this one went missing.

2008 Mazda 3

I used this kit to convert an OEM 4-way flat connector to a 7-way on a 2012 Toyota FJ Cruiser. Easy, straightforward install. Only issue I ran into was that I had to elongate the kit mounting bracket holes to use the existing bracket holes. etrailer provides excellent written and video installation instructions.


The only reason I didn’t give this product a higher rating is we found out, after the fact, that the controller doesn’t allow a charge to our RV battery like a regular plug does. That should be made ;more apparent in the specs of this product. While there can be rewriting workarounds to this, those weren’t satisfactory options so it is causing us to move to a different brake controller. The operation of this controller, otherwise, is excellent. Simple to use, simple to hook to your phone and worked great with our trailer. Unfortunately we need our battery to be working and charging as we travel since we go “off grid” often. If that’s not a concern of yours, this is an excellent choice.

We have researched this question with Curt. They advised that the circuit is only rated for 30 amp peak. The constant amp rating is lower but they am not sure what that number is at this time. With the potential of overheating the unit while charging the battery they would not recommend it.

Only used once, but worked well with rented travel trailer RV using bluetooth connection to my phone. Using this type of Brake Controller avoided having to have one permanently installed. Wished I would have had other opportunities to get more familiar with the settings. But, we decided that this is not the type of RV we want to use. I plan to keep the device for future use just in case.


The controller works great and is easy to connect up with my cell phone. The problem is that plastic pin on the rubber strap & is used to hold the controller in place broke. I am now using plastic tie wraps.

We have the replacement strap available. It is part # C28HR

-- Etrailer Expert Jenny N - 01/27/2023


I have been using this brake controller on 9 trips. The support staff from Curt helped me fine tune the brake sensitivity on my first trip and it has worked very well. After the third trip, I added the rubber strap to secure the controller to the trailer 7-way plug-in and it has been flawless.

I am very happy with the Curt Echo Brake Controller. I recently had to make adjustments to the brake sensitivity in response to adjusting the brake pads and I found that the adjustments on the smartphone app were easy to make. I am very pleased with the product.

Works perfect with Jeep Wrangler and Rp od!

Toyota Echo

My daughter ordered a Curt Echo Wireless Brake Controler from another dealer and it appeared to be faulty. I contacted eTrailer to confirm my diagnosis and they were very helpful and confirmed that the controller was faulty. As we were in a time crunch to get the trailer brakes operational, I ordered a new controller from eTrailer and it worked as advertized - easy setup and control plus three families can use the same controller instead of having to have 3 separate controllers. Only issue is that it took over a week for them to ship the controller even though they showed it in stock when I ordered it.

My daughter used the controller to tow her LARGE pop-up trailer nearly 4000 miles last summer and I used the same controller to pull a separate large trailer 150 miles across a hilly interstate to help a friend move. In both cases it worked perfectly.
Ray - 04/30/2022


Its been a Year , I have it on my Ford Transit 350 Adventure van that I haul a trailer with. I never worry about it not working ( I did when I first put it on) I don't even know if I have the App anymore. I holds all the setpoints in memory. I've been up and down the Grapevine about 6 times with no issues. It dose hang out there a bit but has never fallen out. A little fab work would be good but it hasn't caused me any trouble yet, So Why fix something if it's not broken.


This plug in brake controller works great!
tell all my friends that have rigs to pull.


The BEST Solution by far if your truck didn’t come equipped with a factory trailer brake controller. This thing works folks and you won’t put a crick in your neck trying to install an aftermarket controller under your dash that will forever be in your way! Get one. It’s worth every penny.

  • Compatibility of Curt Echo Brake Controller on Vehicle Equipped with OEM Brake Controller
    The Curt # C51180 will work just fine with a vehicle that is equipped with an OEM or aftermarket brake controller. The Echo will not receive any output from the existing controller, as the Echo doesn't have a pin to receive any output from the controller. The existing controller will not even know a trailer is connected. You will need to make sure that the 12-volt auxiliary power feed to the 7-way is functional. I've linked you to a video that will walk you through how the Echo works.

This brake controller requires no additional wiring and utilizes your mobile device for setting adjustment. It is also transferable to another vehicle once your lease is up. This gives you the benefit of a better proportional brake system but without the knee knocker or difficult installation.

Basically when you apply the brakes in the vehicle that tells the Echo that it needs to start looking for deceleration and to apply a proportional amount of braking on the trailer brakes.

  • Brake Controller Recommendation for 2019 Ram Bighorn 1500 Towing 30 foot Camper
    You absolutely do need a brake controller to tow a 30 foot camper. While your truck might be able to slow the trailer down at a pace that seems reasonable for how large of a trailer you have, you need to have the ability to stop quickly in an emergency situation and the only way you'll be able to do that is with a brake controller installed in your 2019 Ram.
