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 Ford Transit Connect. 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 Ford Transit Connect brakes. The internal sensors respond to the deceleration of your tow Ford Transit Connect 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

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 Ford Transit Connect. With most in-cab brake controllers, there's a bulky unit that must be installed and connected to your Ford Transit Connect'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 Ford Transit Connects. Because it doesn't wire into your Ford Transit Connect at all, the Autowbrake will work with any Ford Transit Connect, 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 Ford Transit Connect - also means that you can switch back and forth between different tow Ford Transit Connects 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 Ford Transit Connect and the Autowbrake will be ready to go.

If your friend's tow Ford Transit Connect 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 Ford Transit Connect 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 Ford Transit Connect. 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 Ford Transit Connect before coming to a complete stop. Using the included key fob, you can adjust the power level either when the tow Ford Transit Connect 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 Ford Transit Connect. 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 Ford Transit Connect - 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 Ford Transit Connect. 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 Ford Transit Connect 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 Ford Transit Connect's brake pedal.

Video Transcript for Autowbrake Electric Brake Controller Review

Speaker 1: Today we're gonna be taking a look at the Autowbrake trailer mount for proportional brake controllers. This works for one, up to three axles. Part number is 3430001. Once you have you Autowbrake mounted right here on our trailer, and this is going to be the ideal solution for hauling a single trailer with multiple vehicles or if you don't want to change the inside of your vehicles. With newer trucks that we have nowadays, finding mounting locations for brake controllers can be a challenge. You've got knee airbags that you sometimes have to deal with or the contour of the dash just doesn't really lend itself to allow us to mount that controller.

This is a really nice set up. It's fully proportional. We can mount it on absolutely any angle. We can mount it flat, up on it's side, and all of our controls are very easily accessible. The only thing we're gonna have inside the vehicle is a very small key fob that's gonna act as out manual override.With the proportional aspect of the Autowbrake, we're never gonna have to worry about getting the braking response that we need.

We have three presets there, so we can go to the right setting for the load that we have on our trailer. And then from that point, the censor inside is gonna sense whether we're trying to slow down very quickly or very slowly and the trailer brakes are gonna match that perfectly. When this senses that we're trying to come to an emergency stop, it's gonna fully apply the brakes from the trailer for us. On the other side of that, if we're just going through traffic and trying to slowly come to a stop, it senses that also. Essentially what this does is when we have that emergency stop situation, we're not putting all of the braking force on our truck.

In the slower stop situation, we're not getting too much braking. So we're not doing too much brake wear to our trailer. Overall, this is gonna make for a very safe system when both the truck and the trailer are doing their fair share of the work, everything is going to be braking appropriately.Now we've used and tested the Autowbrake for almost six months now on this trailer. And this is a trailer we use around the shop here a lot. It's nice that regardless of the vehicle, as long as it have a working seven pull on the back, we're about to plug it directly in.

We don't have any issues. Also it's worked really well. It's been through winter, it's been through a lot of rain going through spring. I think the weather tight casing really does a great job of protecting those internals and insuring that we get proper operation.With the Autowbrake being trailer mounted is, we kinda touched on before, we're not making any modifications inside our vehicle at all. The dashboards anymore look pretty clean and pretty sleek. And we really don't wanna drill extra holes or have a bulky brake controller mounted on their we might potentially hit our knee on as we're trying to get in and out.Now wiring up the Autowbrake is really pretty straight forward. We've got five wires that come off of it. One is gonna go to our 12 volt hot lead coming from our vehicle. One goes to the ground from our vehicle. Then we're gonna have one to the brake controller wire of course, one to the left turn, one to the right turn. And if you have a junction box mounted on your trailer, you can just do that with ring terminals. If you don't have a junction box, they're either fairly inexpensive to pick up on our website, or you can wire it directly to your pigtail coming off your trailer connecting to your truck.Now it is possible to wire the Autowbrake up for use with a four pull connector as well, but we really don't recommend doing that. Basically, you're gonna use your running light signal as the power lead. So you'll have to turn on the lights in your vehicle to have that come through. With all of the after market wiring options tat we have for vehicle, they max out at maybe seven and a half or eight amps. And the Autowbrake is gonna require 15 amps. So generally with any vehicle that's gonna put 15 amps out, it's probably gonna have a seven volt.Now to change the power level in your Autowbrake, we simple are gonna have out vehicle on, or at least power coming to the Autowbrake. And you'll need to hold down the brakes in the truck. You'll see as we go through our settings here, the LEDs gonna flash and indicate which mode it's in. You see this is a triple flash and it happens three times in row. That means we're on the highest setting. If we we're to hit it again, it should now go to double flash. That's gonna do that three times in a row. That means we're in that mid-level. And once more, we'll just have three single flashes. That means it's in the lower setting. Now for the low setting, that's gonna be for trailers up to 3500 pounds. Middle settings gonna be great for trailers between 3500 and 6900 pounds. And for the high setting, that's gonna work out really well for those 6900 up to 12000 pounds trailers. Once we have that set, we'll simple release the brake and the last setting will be saved. Next time we turn it on, it's not process we'll have to go through again.Now once we have the main adjustments done for the weight class of our trailers, we're then gonna have the two buttons here on the outside. Those allow us to adjust the gain up and down. So give us more braking force or less braking force. So allows up to fine-tune it. It's very similar to most brake controllers out there on the market you can really fine-tune it to that exact power that you need. And in the event that we have sway incident where our trailer starts swaying, we can simply hit that middle button which is gonna act like a manual override on any other brake controller. That's gonna apply the brakes on our trailer to help get that back and under control.As you can see, it's really a lot smaller than most key fobs you're gonna have. Its pretty thin, pretty narrow so I don't think it's gonna take up a whole lot of room on that key ring if you decide to have it there, or it can be easily stored in a small compartment.Now of somebody decides to use or barrow you trailer and they have their own brake controller already set up in their vehicle, they're more comfortable using that, the Autowbrakes gonna go completely into a sleep mode. When it's in that sleep mode, our brake controller inside the vehicle can be used the entire time. Once we get connected into a vehicle that doesn't have a brake controller, it's gonna go right back into it's standard mode.Just to insure you have the space to mount the Autowbrake, well give you some measurements. The top to bottom here is gonna be five and quarter inches. Side to side we're looking at six and seven eighths. And then from your mounting surface to the top, it's an inch and half.Now like we said, we've been using the brake controller for quite a while on this particular trailer. Bob is one of our guys here, he does a lot of the technical stuff here at Etrailer. This is his trailer, he's been using it for quite a while. He's also use proportional brake controllers in the past. I really enjoyed the experience I had out of it. Based on your experience with your old proportional brake controller, how was this one similar, different, the same What'd you think about it Bob: So for me, the best thing is that this trailer gets used by a lot of people. So anyone can come plug it in and I don't have to worry about them stopping after they load the thing down because the brake controller is already here. So if they don't have one in their truck, there's no worries, the trailers still gonna help them stop. So when I use my MCAB controller, I had the ability to see where I'm set at and I know it because I've used it for a very long time. But if that system we're to break down, I would still have brakes here on the trailer. That's the things that I really like about it. Speaker 1: As far as the performance out of the Autowbrake versus that one, can you tell any real difference Bob: With this unit, you can tell a difference when you first start towing the trailer each time after you plug it in because it has to learn the weight of the trailer every time. It's not something you really notice except for when you first start using it because it's a little different. It actually applies the brakes a little hard the first couple of stops. It learns the weight of the trailer and then it smooths out and it's just like a proportional controller. Speaker 1: Now as far as the remote control aspect of it, you know how to load the trailers, you don't probably have to worry about sway too much, but with the adjustability, you can adjust that gain up a little bit, adjust it down a little bit and kind of fine-tune it. Did you find that that works similar to other brakes controllers or was it more of a challenge Bob: That works pretty well. You don't have a read out on your display in the cab to go by so that's the challenge of it. Speaker 1: We're setting it by feel. Bob: You can actually once you get it set, apply the brakes and test it and then you can tell that it is making a change. Speaker 1: Awesome. Well thanks for the info boss.And that will complete our look at the Autowbrake proportional trailer mount brake controller part number 3430001.

2010 Dodge Durango

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 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
