Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking, or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner. Just select a boost setting, set the power output level, and you're good to go.

As long as the Reflex controller is properly mounted according to the included instructions, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This dual-axis, inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Built-In Controls for Adjustable Power

Curt Reflex Controls and Components

The above diagram shows the controls and components of the Curt Reflex trailer brake controller.

  1. Digital display
  2. Load range calibration button
  3. Thumbwheel power output control
  4. Slide-bar manual override

Load Range Levels

The Reflex offers 4 different load range (or boost) levels. These settings are designed to give you more or less initial power output based on your trailer's weight. The load range levels let you alter the sensitivity of the brake controller's internal sensor, thus increasing the initial power output to the trailer brakes to better compensate for weighty loads. To set the load range, press and release the button on the front of the controller until your desired level appears on the screen.

So, if you boost the initial power so that the sensor is more sensitive, your trailer brakes will activate with more intensity right off the bat. This means that they will also reach maximum braking faster simply because they will start out at that higher intensity. This is particularly beneficial if you are towing a heavy load because the intensity required to stop that load may be far greater than that needed to halt your vehicle. Therefore, sending out more initial power to the trailer brakes - and causing them to reach maximum braking faster - allows you to better control the trailer so that it doesn't push your tow vehicle before coming to a complete stop.

Output Control

Once you set the load range level, you can adjust the overall power output by moving the thumbwheel on the side of the controller. This setting ranges from 0.5 (minimum output) to 9.9 (maximum output). This indicates the maximum amount of power that will be sent back to your trailer brakes when you apply the brakes in your tow vehicle. Optimum output should cause your trailer brakes to function effectively without locking up.

Safety Features

The Reflex offers advanced safety features to prevent damage to various components of your towing setup. When the Reflex is not in use, it will be in power-saving mode, reducing the power draw to minimize drain on your vehicle's battery. This power-conservation mode begins after 1 hour of inactivity and ends the moment your vehicle's brake pedal is pressed.

When you stop at red lights, or any time that your truck and trailer are at a standstill with the brakes applied for a prolonged period of time, the Reflex will reduce the power output to your trailer's brakes, preventing them from overheating.

If ever there is a time that you need to brake your trailer separately from your tow vehicle, the manual override lever is easily accessible. Pushing this slide engages the brakes on your trailer with full power.

Automatic Leveling and Simple Installation

The self-leveling feature of the Reflex 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 that is within 90 degrees, and the controller will level itself automatically. Make sure that the controller is also positioned so that the side-to-side angle is within ±20 degrees.

Curt Reflex Mounting Range

Installation is a snap. After mounting the Reflex unit in your cab using the included bracket, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller.

Installation Accessories

For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

Note: If a custom brake control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

See also'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.

Video Transcript for Curt Brake Controller C51130 Review

Today we're going to review part number C51130. This is the Curt Reflex Trailer Brake Controller. This is a proportional designed brake controller which will activate your trailer brakes in proportion to your vehicle's braking action. It will automatically adjust the trailer's braking based on the deceleration of the tow vehicle. This does activate immediately so there's no pausing like with some of the time delay brake controllers. It does contain an automatic leveling ability.

It has an internal sensor which will detect any deceleration even if the controller is not mounted flat. When you install this it can be positioned at any angle vertically up or down 360 degrees full rotation pretty much. Horizontally there is a limit-its 20 degrees side to side. So this way 20 degrees and this way 20 degrees or 20 degrees this way, 20 degrees that way. So there is a limit horizontally.

It does have four load range levels. This button right here will get you your load range levels. Our boost settings it'll let you adjust your initial braking power and aggressiveness. It does have a dual access accelerometer which will ensure smooth stops. This brake controller does do a constant diagnostic check which will alert you to any potential problems.

A few integrated safe guards it has to protect the vehicle, the trailer or the controller is one it minimizes the drain on your car battery by entering a power conservation mode after one hour of inactivity. If it isnt used for one hour it will go into the conservation mode. It will help keep your trailer brakes from overheating by reducing the power output to them during prolonged stops and it will prevent brake controller and trailer brake away system against any shorts. It also has a built in polarity protection which will prevent any positive or negative power problems when it is installed wrong. The digital display right here will show you the load range settings and any air codes.

The button I mentioned is for the load range and also for calibration. Right here it has a built in-if I show you when I push it-it has a built in slide bar manual override which is used for emergency braking situations. It does come with the mounting bracket which can be slid on and installed. The top is the holes has mounting screws that can be used or it also has a double faced sticky tape that can be used. Also has a nice little card which will have a-it's a quick reference guide which will show you what some of the display would be indicating. This part is made in the USA and now what I want to do is connect it to a power source to show you what the display read out would look like. What I have here is a Curt Universal Wiring Adapter that's used to mount a Curt Brake Controller in a vehicle that might not have a factory brake controller port. On one end is the port that would snap into the Curt Brake Controller, the other end will be pigtails which I right now have wired to a power source. Basically right now I'm going to show you if we turn on the power as you can see it's flashing CL and what that means is it needs to be calibrated so what you would do is push and hold that button and when you hold the button once it's calibrated it'll come on and be a constant CL instead of it flashing. When you let it go it'll just show you the two dots. The two dots basically mean that the trailer is connected and you're ready to go. If it only showed one dot that would mean the trailer is not connected. Basically what you want to do is-it has four load range settings-our boost settings. Basically you just push this button-you can see load range one, load range two, three and four. Basically the load ranges would be when you put it in one that would be if you're towing a trailer that might weigh less than your tow vehicle weight. If you're trailer is going to be equal to the tow vehicle you would want to go to load range two and if the trailer's vehicle weight is 50% more than the tow vehicle you would want to go to three and then load range four would be if it's 100% greater than the tow vehicle weight. Once you find the load range you want to put it in-let's say one right there then there's a knob here on the side that you can turn it-you can see that it'll range from .5 all the way up to 9.9. That's the amount of brake output it would be. So in Load range one we're going to set it at let's say at 6.1 now it goes off and you're all set at load range one with a 6.1 setting. If you have an emergency braking situation as you push this manual override you can see the brake output increasing and if you go all the way it will do the 6.1 you have it set at. Those would be the settings you would do on your brake controller. The application for this that will work on trailers up to four axles or eight brake assemblies. It is designed to be used with an electric or electrical hydraulic trailer brakes and it does come with a limited lifetime warranty. That should do it for the review of part number C51130 the Curt Reflex Trailer Proportional Brake Controller. .

It sure doesn't get much easier than that! First the shipping was upgraded, so the unit arrived really quickly. Installation was easy, but I did appreciate the additional information provided by etrailer in-case you did run into a problem. The product itself appears very well constructed and has a solid feel to it. Overall I am very happy with both etrailer and Curt Brake Controllers. Thanks for a great service. 125923

The product seems to work as expected. I think they could improve on the display: You're given a character, a dot, another character, and another dot. With only these 2 characters and 2 dots, the unit is trying to give you a lot of info, so they have to do it with abbreviations, which you have to keep the little card handy to decipher. I keep mine clipped to the sun visor. At the very least, know this - 1 dot means no trailer connected, 2 dots means there is a trailer back there. Roll a little bit and pinch the controller. If it slows you down, you're good to go. 388883

Although alot of people pick some controllers that are around $50 I highly recommend this certain controller. It is money well spent. Installation was a breeze about 10 minutes and calibrating was even easier with a push of a button. After hooking up my travel trailer I could tell the difference in my stopping power. I feel this product will protect my investment and keep my family safe during travels. A definite gold star rating 183502

Product works very well with my trailer. Install was as easy as could be expected. The only issue I had was the adhesive pad I used to secure the controller mount gave out. I had to screw the mount in. Just plan on screwing in the mount to your dash and don't rely on the adhesive pad alone. 303543

I use it almost daily and depend on it. I was asked to tow someone elses trailer recently. They guy said it had a 7 way plug, so it had brakes. I hooked up to it, and my Curt said 0.C on the display. I told the guy that my Curt said NO BRAKES attached and refused to tow. He emailed me later and said good call because they found that the hangers for the shackles had broken the weld as well when they were looking at the brakes.

Do you have a question about this Brake Controller?

  • Trailer Brake Controller Recommendation for a 2014 Dodge Ram 1500
  • Dodge introduced a multiplex type of wiring called Powernet starting in 2013. Traditional brake controller harnesses would not work with it. So manufacturers developed a new harness that will work with the Powernet. The dealer may not know of the aftermarket options and the new wiring harnesses developed for use with the Powernet system. But you can very much install an aftermarket one if you want to. If you like Curt brake controller # C51130 then for a 2014 Ram 1500 you will need harness...

  • Trailer Brakes Not Working with 2014 Ram with Factory Integrated Brake Controller
  • If the trailer is using electric over hydraulic brakes then that is likely the issue. If the factory brake controller has an electric over hydraulic mode it would have to be in that mode to work with EOH brakes. If the trailer has regular electric brakes then make sure that the output setting is up high enough. Since the trailer brakes work fine with another vehicle it doesn't seem like the trailer or the brakes are the issue. But you can make sure that the truck and trailer side connectors...

  • Brake Controller Wiring Harness for a Reese Brake Controller on a 2014 Ram 1500
  • The issue is that Dodge started using the Powernet electrical system starting in the 2013 model year. This is a multiplex wiring systems so it is more complicated than pretty much everything else that came before it. A regular harness will not work so they developed a special harness just for this system and it is the only one that you can use. However, you do not need to run the additional wiring back to a third brake light wire. Everything still plugs in under the dash. The harness...

  • Is the Factory Integrated Brake Controller on a 2015 Ram 1500 Proportional or Time Delayed
  • The factory integrated brake controller for the 2015 Ram 1500 is proportional. For more information on it I would peruse the Ram website. We do get a lot of questions about the performance of the factory controllers and people wanting to switch to an aftermarket controller, especially if they are towing a trailer with electric over hydraulic brakes. If you are in the market for a new truck you might want to consider skipping the factory controller option and get an aftermarket one....

  • Troubleshooting Curt C51130 Reflex Brake Controller
  • I think it's unlikely you have a bad controller. I looked up your order history, and noticed that you have a Curt Reflex brake controller, part # C51130. The Reflex controller is a proportional type controller, which means you won't get much of any voltage at the trailer connector unless the vehicle is moving. You should get voltage at the trailer connector with the manual brake switch actuated, but you won't get anything with the brake pedal except for a very weak signal. If voltage...

  • Brake Controller Recommendation for a 2014 Dodge Ram 1500
  • There are only a few brake controllers that are confirmed to work with the new multi-plexed wiring of the new Ram trucks. The Hayes controller you have would not be one of them unfortunately. What you would need is a new controller and correct install harness, part # 3023-P. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup.

  • Difference Between the Curt Triflex and Reflex Brake Controllers
  • The biggest difference between the Curt Triflex part # C51140 and the Curt Reflex Brake Controller part # C51130 is that the Triflex uses a triple-axis accelerometer and the Reflex uses a double-axis accelerometer. The triple-axis will ensure that you get smooth consistent braking in all braking situations. Because of that I would recommend the Triflex.

First, if your Commander does not already have a 4-Way, you will start by installing one using # 118408. I have included a video showing a typical installation for you. Then you would need a 4 and 7-Way installation kit # ETBC7. This will provide the 7-Way and the wiring and accessories needed to install a brake controller. I have...

  • Fit & Compatibility of Upgrading to a Proportional Brake Controller on a 2001 Ford F-350 w/# 3035-P
  • Yes! Both the Draw-Tite Activator # 5504 and # 5100 time delayed brake controllers and the Draw-Tite I-Command proportional brake controllers will use the same # 3035-P wiring adapter for your 2001 Ford F-350 Super Duty. So it will be a simple switching out for your truck. The Curt Reflex # C51130 will need you to get a new adapter # C51322 for it to be compatible with your F-350. One thing that may help make the decision for you is that the Draw-Tite # 5535 is designed for electric...

  • Does Computer Have to be Reprogrammed when Installing Brake Controller on 2014 Ram 1500
  • The only time I have heard that the computer on the 2014 Ram has to be reprogrammed is if you are replacing the factory integrated controller with an aftermarket one. If you are not doing that then you should not have to have the computer reprogrammed. It certainly would not hurt anything to do so if it will give you peace of mind.

  • How to Install a Trailer Brake Controller on a 1993 Ford F-250
  • If your 1993 Ford F-250 came with a factory installed 7-Way trailer connector then you can plug in a brake controller since all the tow package wiring will be present on the vehicle. A brake controller would plug in to a plug under the dash. You could use Curt brake controller # C51130 and wiring harness # C51312 to plug it into your F-250. The factory plug is located underneath the dash, to the left of the steering column, and it is taped to another harness near the emergency brake...

  • How Does Curt Reflex Brake Controller # 51130 Connect Using Harness # 51453
  • The Curt wiring adapter # C51453 is vehicle-specific and is used to connect a Curt brake controller like their Reflex # C51130 into a compatible Dodge Ram. In such an installation the black connectors from the controller and harness join together and the grey connectors on the harness will plug in to the under-dash port on the truck. If you were to want to hardwire the Reflex into just about any vehicle you could use the pigtail harness # C51515.

  • Under Hood Connections Required to Make a Brake Controller Functional on a 2007 Chevy Suburban
  • There are two wires under the hood of your 2007 Chevy Suburban that will need to be connected before your 7-way is totally functional. One of the connections is for the 12 volt power wire circuit and the other is power supply for the brake controller. It sounds like you have not made these connections yet and that is the problem you are experiencing. Check out the FAQ article I attached that details exactly how these connections are made. If you fast forward to the 3:36 mark of the...

  • Trailer Brakes Lock Up No matter What Setting is On the Brake Controller in a 2014 Ram
  • Usually when electric trailer brakes lock up it is because the brake pin on the trailer side connector is getting constant power. If you are using a 6-Way trailer connector or a 7-Way to 6-Way adapter then the likely cause is that the 12 volt circuit and the brake output circuit are switched. This switch happens because there are 2 ways a 6-Way can be pinned out. The center pin will either be 12 volt power or electric brake output. If you are using a 6-Way or adapter for a 6-Way all...

  • Troubleshooting LED Light Working on Curt Reflex Brake Controller When Brake Pedal Is Applied
  • Since you have checked the third brake light and it has tested fine, then the problem seems to be somewhere between the brake pedal and controller or inside the Curt brake controller # C51130 itself. Now, it may be possible that the controller is bad, but there are a couple of tests you can do to eliminate other possibilities. Test the red wire coming out of the brake controller. If there is no signal when the brake pedal is engaged, disconnect the wiring harness from the port of the...

  • Recommended Brake Controller For 2007 Dodge Ram Pickup
  • The Curt Reflex Trailer Brake Controller is an okay controller. For the price point, I do recommend a different brand as we have seen more issues with Curt controllers than others. My recommendation for a better unit is the Tekonsha Primus IQ # TK90160. If you are looking for a step up from that, I recommend the Tekonsha Prodigy P2 Trailer Brake Controller - 1 to 4 Axles - Proportional # 90885. This is one of our best sellers due to its consistancy, features, and price.

  • Trailer Brake Controller Recommendation for a 2014 Ram 1500 Diesel
  • The Curt brake controllers are fairly new. But the controller that I recommend, almost exclusively, is the P2 # 90885. The reason I recommend this controller so often is because it has proven to be reliable, easy to use, and easy to set up. It is the most popular controller we have. To install it on your 2014 Ram you will also need wiring harness # 3023-P. And if you live in or will be traveling through California, you will also need adapter # 30235-P to be in compliance with California law.

  • Brake Controller Compatibility 2013 Ram 1500
  • Beginning with the 2013 model year, Ram started using a multiplex wiring system to carry the stop lamp switch signal. Because of that, not all brake controllers will be compatible. Dexter doesn't offer a harness that's compatible with your Ram, so I'd recommend a different controller. The Curt Reflex, part # C51130 would be a compatible controller that would work great for you. You'd also need the # C51453 wiring harness. If you click the provided link, you can see exactly where the...
