Proportional Braking

Autowbrake unit

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 set the initial power level, and you're ready to go.


Using a series of accelerometers, gyrometers, and a sophisticated computer program, this brake controller will sense how your tow vehicle brakes. The internal sensors respond 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.


Trailer-Mounted Brake Controller

Autowbrake brake controller mounted on A-frame trailer Autowbrake trailer mounted

The Autowbrake mounts completely on the trailer. There's nothing in the cab to get in your way, so you don't have to worry about banging your knee on the controller as you enter and exit your vehicle. With most in-cab brake controllers, there's a bulky unit that must be installed and connected to your vehicle's brake light switch. You have to determine where to mount the unit in your cab and make sure it doesn't interfere with lower airbags. The Autowbrake removes all of that hassle. It's convenient, out of the way, and works in all tow vehicles. Because it doesn't wire into your vehicle at all, the Autowbrake will work with any vehicle, whether it has an older standard wiring configuration or a newer PWM or multiplex system.


The fact that the Autowbrake installs on your trailer - and not in your vehicle - also means that you can switch back and forth between different tow vehicles with no additional setup. For instance, if you lend the trailer to a friend or co-worker who doesn't own a brake controller, all he or she has to do is plug the trailer into the tow vehicle and the Autowbrake will be ready to go.


If your friend's tow vehicle already has its own integrated brake controller, that's not an issue either. When the Autowbrake senses another brake controller, it automatically goes into sleep mode. There is no need to disconnect the unit. No additional action is required. This gives you the flexibility to use your trailer with almost any vehicle without issue.


Autowbrake Operation

The Autowbrake features different settings that you can select to tailor the unit to your trailer and to your desired braking sensitivity.


Autowbrake gain setting

First, you will need to select one of the weight-based settings. This will ensure that you have the proper amount of braking power for the load you're towing. When selecting a setting for your trailer, the Autowbrake's LED light will blink multiple times to signify the different settings.


Autowbrake light

The light will blink 3 times for Setting 1, 6 times for Setting 2, and 9 times for Setting 3. This way you will be able to confirm that the unit is properly calibrated based on the weight of your trailer.


  • Setting 1: up to 3,500 lbs
  • Setting 2: 3,500 lbs - 6,900 lbs
  • Setting 3: 6,900 lbs - 12,000 lbs

Adjust Autowbrake power levels with key fob

Once you have the correct setting selected for your trailer, you can choose between 5 different power levels to get the desired amount of braking power and aggressiveness for your setup. If you're towing a heavy load, the braking intensity required to stop that load may be far greater than what's needed to stop your vehicle. Increasing the power level will enable your trailer brakes to reach maximum braking more quickly. This allows you to have better control of your trailer, ensuring that it won't push your tow vehicle before coming to a complete stop. Using the included key fob, you can adjust the power level either when the tow vehicle is stopped or while you are driving.


Thanks to the Autowbrake's Smart Start feature, there's no need to re-adjust the settings every time you tow. The unit will always remember the last towing setting, even after it's been disconnected. This means that you can store your trailer away for the winter, and when you're ready to use it again, all you have to do is plug your trailer back into your tow vehicle. The Autowbrake unit will automatically boot back up to the last setting. There is no need to adjust the settings unless you are going from an empty trailer to a fully loaded trailer - or vice versa.


Autowbrake manual override

The manual override button can be found on the included key fob. If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - just press the middle button on the fob. Additionally, the manual override can be used to help correct trailer sway while driving. To correct trailer sway, press the override button on the key fob and continue to hold the button down until your trailer falls back in line with your vehicle. Then release the button and continue towing. When you press the manual override button, your trailer's brakes will activate with the intensity of the setting you have selected.


Simple Installation

Autowbrake installed

The Autowbrake unit can be mounted at any angle and in any direction using the 4 included self-tapping screws. It's best to mount the Autowbrake close to the trailer junction box, which is typically located on the trailer frame. However, it can be mounted in the location that works best for you - inside a trailer compartment, under or along the side of the frame, or inside a storage cabinet or toolbox.


Using the junction box to connect the Autowbrake wiring harness is recommended. If the junction box is not accessible or if your trailer does not have one, you can splice the wires directly into your trailer wiring harness.


Making the wiring connections is easy. The Autowbrake harness contains 5 color-coded wires:


Autowbrake wires

Blue - trailer brakes

Black - power wire

White - ground wire

Green/Yellow - brake/turn signal lights


Autowbrake wires into junction box

Connect each of the wires in the Autobrake's harness to the appropriate stud in your junction box. If you do not have a junction box, splice the harness into your trailer's wiring. Before beginning, be sure to confirm the wiring configuration of your trailer. Color-coding does not guarantee that the circuit you are connecting to is for the desired function. A circuit tester is recommended.


Autowbrake wiring diagram

Connect the black wire to the 12-volt auxiliary power stud or wire. Connect the blue wire to the trailer brake output. Connect the white wire to the ground stud or to a suitable grounding point on your trailer's frame. Connect the green wire to the right stop/turn connection and the yellow wire to the left stop/turn.


Autowbrake unit buttons

Once the Autowbrake is mounted and installed, calibration is a 1-time process that will need to be performed by 2 people. Calibration is required the first time you install the Autowbrake, but that's it. You need to re-calibrate only if you reposition the Autowbrake or move it to another trailer. Calibration should be done on a level surface. This allows the Autowbrake to determine what the normal towing position will be.


To calibrate, turn on the vehicle ignition and press the brake pedal down. While the brake pedal is depressed, have a friend press both buttons on the Autowbrake unit simultaneously until the LED starts blinking. Once the LED stops blinking, press and release the Gain button. The LED will start blinking again. When it stops blinking, the Autowbrake is calibrated and you can release the vehicle's brake pedal.

this review is about the AuTowbrake Electric Brake Controller. I have used many brake controllers and i was never satisfied with any of them plus I just bought a new truck and didn't really want to start drilling holes to mount a brake control device under the dash. I read reviews and saw some videos of this one and it caught my attention. The install was simple, it took about 10 minutes. I was fortunate because my Trailex was new and had a color coded junction box. I followed the simple install instructions that came with the controller and i was good to go. The calibration process was quick and easy. Now the part i was waiting for...to see how well (or not) it actually worked. I tow a 3100 lb car on a 900 lb trailer with a durango and with my tow vehicle and previous brake controllers, there was always some discrepancy with the brake power between that of the truck and the trailer...i went slow at first and it was perfect, i stopped the trailer at higher speeds and still perfect. no pushing of the truck or tugging of the trailer. 529770

  • Comparing Autobrake and Prodigy RF Brake Controllers
  • Both the AutowBrake part # 3430001 and the Prodigy RF part # 90250 are excellent options for trailer mounted brake controllers. The Autowbrake is designed for more of a permanent install as it hardwires directly to the trailer's wiring and is a bit smaller. It uses what looks like a key fob too for a remote. The RF connects by plugging the trailer's 7-way into it and then it's 7-way into the vehicle's 7-way socket. It's a little easier but maybe not quite as permanent. It's a bit larger...

  • Using the AutowBrake Brake Controller with a 1999 Toyota 4Runner and a 1997 Toyota Previa
  • Installing the Autowbrake brake controller, part # 3430001, doesn't actually requrie you to make any changes to the 4-way connectors on your vehicles. All it needs to function is to be wired to the proper wires on the trailer and a constant power source. If you want, you can wire the Autowbrake's power wire (the black wire) to the trailer's running lights and then it will have power as long as you tow with your lights always on. The downside to this is you will then always be drawing...
