Specs:
The high-quality OLED display on this brake controller makes the screen easy to read at a glance. The text is large and you can tilt the screen to the angle that makes it easy for you to see. Instead of displaying codes that you have to look up, this display shows full-text descriptions of errors so you can quickly address any problems that come up.
Braking 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. Use the + and - buttons to set the output. 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 this setting unless the trailer load changes, you switch trailers, or road conditions change. The OLED display will show the current output setting being used.
Sensitivity: Once you have the output set, you can fine-tune the power by adjusting the sensitivity of the internal sensor. This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the set output level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does. The sensitivity setting gets the braking power to your trailer brakes faster and with more intensity so that it doesn't push your tow vehicle forward.
There are 9 sensitivity levels (boost levels), with 1 being the least sensitive. At level 9, the sensitivity of the internal sensor is as high as it can go. Press both buttons at once to switch into the sensitivity mode and adjust to the level you need for smooth, safe braking. When you change the setting, the display on the Assure will flash the level before reverting back to showing the power output.
Manual Control: The manual override button on the Curt Assure is pressure sensitive for precise braking power. When you press the button, the trailer's brakes will be activated with the same amount of force, without activating the brakes on your tow vehicle. This is great for stopping sway or controlling your trailer's momentum in emergencies. The braking intensity will be indicated on the OLED display when you press this button.
The Assure offers key safety features to prevent damage to various components of your towing setup. This starts with built-in protection against shorts and positive and negative power reversal, as well as continous diagnostic checks to alert you to any potential problems as they come up. To minimize the drain on your vehicle's battery, the controller will automatically go into power-saving mode when not in use. This feature will turn on after 30 minutes of inactivity and turn off again the moment you press the brake pedal.
Another great way that the Assure protects the longevity of your setup is a hold feature that saves wear on your brakes. When you're waiting at a red light, you don't need your trailer brakes on at full power. The longer you sit there, the more they will overheat. But with the Assure, any time your tow vehicle and trailer are at a standstill for a prolonged period of time, the controller will reduce the power output to the brakes. This will keep your trailer in place while saving your brakes.
The self-leveling feature of the Assure ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at a vertical angle within 90 degrees, and the controller will level itself automatically. This makes the installation that much easier. But keep in mind that the Assure must be horizontally level and parallel with the direction of travel to work correctly.
Installation is a snap. If your vehicle already has a plug-in brake controller wiring harness, just connect the unit to it. Otherwise, you will need to purchase a vehicle-specific wiring harness (sold separately) to plug into. If a harness is unavailable for your vehicle, hardwiring will be necessary.
Installation Accessories
See also etrailer.com's exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.
Note: If a custom brake control wiring adapter is not available for your vehicle, either a 20-amp or 30-amp circuit breaker (sold separately) may be required for installation.
The Curt Assure 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 Assure uses an internal inertia sensor to detect 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 slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.
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 junction box beneath your vehicle's dash.
Features:
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 that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.
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.

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.
With the adapter kit, installation was easy. Controller is very responsive when towing.
The resources at etrailer.com made my purchase easy. By having specific truck lookup ,correct wite adapter and specific product videos. Looking forward to my first trip with curt assure brake controller.
2006 Dodge Ram. Easy install. Plug it in and tie up the wires. I put a wire protector sleeve to cover the wires coming out of the controller.
Plug and play, no drama.
VERY easy install. As mentioned in other reviews the hardest part is finding the factory plug in for a 2017 Tacoma. Toyota tucked it way in the back behind a wire bundle. Picture attached for reference.
Good prices and selection but the shipping was pretty slow. Almost had to go buy a cheap brake controller to get my towing job done. I'd buy from etrailer again without hesitation assuming I didn't need it right away.
The Curt electric brake controller was the easiest installation I have ever had. I ordered the custom wiring adapter along with the brake controller; it all came with easy to follow instructions and it only took about 30 minutes to install the entire unit. I had done some checking around to get estimates from various companies which do the installations and their costs were around $300.00. The Curt unit including the adapter wiring was $**.00 and a very easy install. I used the brake controller during a recent camping trip on which I was pulling a 24 foot camp trailer. The controller worked great and I could easily control the trailer in some extreme mountainous terrains in Wyoming.
Great customer service
Quality parts with excellent communication
The adapter is as advertised, although I have an older brake controller that I had to do a small amount of wire splicing.

Just fine.
The directions on this item are horrible. I finally figured it out and was able to install it onto my Ram 1500, but only after spending hours trying to make everything fit right. If you're looking for a hitch setup to pull a trailer long distances, I would advise you to look at other options. This will work for my short trips with my half-ton pickup, but I would not want to pull anything more than 50 miles with this setup.
Qaulity product and easy installation. Fast shipping.
Controller worked great. Stops smoothly and properly. The only problem is when I disconnect the trailer the display continues to say there’s a problem and won’t stop until I unplug it. Called technical for help and he said there’s a short somewhere but I haven’t found any short or cause.
Bought this trailer controller cable with a Curt Trailer Brake Controller. I dont know if it works or not. I installed this along with thr trailer brake controller at the same time. Nothing works. No lights power up on the controller. I highly respect Curt Products as I have many installed on my truck, but I'm disappointed with this combo purchase.
Part functioned as required
Noah A did a fantastic job of making sure I had the right product and referred me to their video library for installation instructions. Absolutely a fantastic representative of this company 5 out of 5 stars for sure. Good follow up as well!
Made brake controller install ridiculously easy. Thanks Etrailer.com

Made the installation of brake controller super easy. Absolutely worth it. I wouldnt do it any other way after using this.
The product worked great, but I am annoyed because etrailer wouldn't take it back even though I hadn't used it.
Given the fact that I only planned to tow my travel trailer one way up to the lake, I wanted an inexpensive brake controller. I looked online and in stores, and they were all over $100. When you added in the wiring. The controller I purchased from E-trailer only cost $49.99 including the wiring. I simply plugged it in, and after a short test tow, it works great. Took about 15 minutes to install. I'm very satisfied with my Curt brake controller. Got it in 3 days after ordering. Arrived fast, installed fast, and works great at a great price. What more can you ask? I'll be ordering from E-trailer in the future. Thank you.
Great product, plug and play with brake controller. Install was 10 minutes. Fast delivery with tracking. Price was lower than anywhere else.
The wire harness made things plug and p lay.
Appears to be the correct harness as the plugs match the brake unit and the splice in GM pig tail that came with the truck. Bought it to avoid cutting and splicing as well as avoiding voiding the brake unit warranty. Big Benefit also that I can unplug and move to another vehicle if needed Had the unit within 5 days including the week end, that's great customer service by etrailer
Awesome company. Install was simple and delivery was as fast as I ever had. Highly recommended them.
Customer service is awesome needed this to pickup my trailer tomarrow they were able to get it to me next day. Also ygis trailer brake literally plug n play on 2003 chevy suburban.
Much smoother braking than my previous controller that the RV dealer put in. Curt has excellent customer service.
