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.

As long as the Agility controller sits level on a horizontal plane and is pointed in the direction of travel, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This 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.

Power and Sensitivity Adjustment

Getting the braking power you need for your application is simple with the Agility. First, set the overall power so that you can achieve maximum braking without locking up your trailer brakes.

Once you have the overall power set, you can fine-tune the power output by adjusting the sensitivity of the internal sensor. Use the adjustment buttons on the top of the controller to achieve your desired degree of intensity. There are 5 levels to choose from. The first level offers the least amount of sensitivity, making it ideal for lightweight setups. The heavier your load, the higher you will want to take the sensitivity. At level 5, the sensitivity of the internal sensor is as high as it can go. This level provides the most aggressive braking and is ideal for heavy loads.

Digital Display

On the front of the Agility there is a digital display that is designed to keep you aware of the braking action of your trailer. This screen shows your sensitivity level, overall power percentage and error codes for issues such as a short circuit.

Simple Installation

The Hopkins Agility can be mounted anywhere within 360 degrees vertically, but it is recommended that it be mounted in your cab at an angle that is between -20 degrees and 70 degrees to make it easier to access.

Correct Agility mounting90-Degree Agility mounting

Note: The Agility must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.

To install the Agility, a vehicle-specific wiring adapter (sold separately) is required. These custom kits are 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.

Video Transcript for Hopkins Brake Controller HM47294 Review

Today we are going to review part number HM47294. This is the Hopkins agility proportional trailer brake controllers designed for trailers with one to four axles. Comes with everything showing here, the controller, the mounting bracket, and the mounting hardware. Now, this brake controller will activate your trailer brakes in proportion to your vehicle's braking action. It automatically adjusts the trailer braking based on your deceleration of the tow vehicle and it does activate immediately so there is no pausing like with your time delayed brake controllers. It does have multiple mounting options. The agility must be mounted on a level, horizontal side to side plane. In other words, you do not want it this way or like this.

You want it to be horizontal and you want it to be going in the direction of travel so the internal sensor will function properly. It can be positioned at any angle, up or down, in a vertical plane. Basically it could do 360 degrees, but it is recommended to be able to view the screen that you mount it between a minus 20 down and a 70 degrees up. That is your recommended mounting. Now, it does have a digital display right up here. It is a very easy to read. The screen shows your sensitivity level, overall power percentage, and it even shows air codes for issues such as a short circuit. Now, on top has the power adjustment buttons, a plus and a minus, this will adjust your power sent to the trailer brakes.

It will be displayed as a percentage on the digital display from 5 to 99 in increments of 5 percent. The sensitivity feature which is right here on the side, it is a button, you push that. It has 5 different settings and that will make your trailer braking response more or less sensitive. Setting one would your least sensitive and setting 5 would be the most sensitive and then the air code SC, if it shows on here, would mean it is a short circuit. I am going to hook this up here in a minute just to show you those. It has a built in right up here manual override lever.

You can see this button when you push down that will override it and give you an immediate response to the brakes. It has a plug here on the controller. Now we do recommend when you install this to get a plug in vehicle specific brake controller adapter. We do sell those separately. to see if there is one for your vehicle we recommend you go to our website and under our fit guide check your year and model vehicle to see if there is one available. It is required to install this. Now we also sell a plug in that will plug into this if you cannot use a vehicle-specific adapter we do also sell one that is a plug to plug into this and the other end would be a four pigtail wires that you could hard wire into your vehicle.

We also sell those separately. Again, the application on this is for trailers with up to four axles or 8 brake assemblies and this is designed for use with electric brakes only. Here is what I am going to do is I have a connector hooked up to a 12 volt power source. I will go ahead and plug this in and then what you are going to notice when I turn it on, I have all the wires hooked up, you are going to see first comes on to set and then it will go to just a single red dot and when it shows a single red dot that is meaning the trailer is connected and you are ready to go. Now, if that dot did not show that would mean the trailer is not connected. You would have to make sure the trailer is connected. So with it in that position you are ready to go. Now, as far as the top, the power adjustments you can see here is the plus, so right now it is at 50. So you could do 55, 60, 65 and again, you go by 5 percent or you can go down 65, 60, 55, 50. And on this side we mentioned the sensitivity. If you push that you will see 2, 3, 4, 5 and then back to one. So you got 5 sensitivity features. And, then again, your manual override it if you have to apply the brakes immediately. You just push down on it. You can see that if you push it down gradually, it will ramp up gradually. But that should do it for the review on part number HM47294. The Hopkins agility porportional trailer brake controller with trailers with one to four axles. .

I was able to install the brake controller in less than five minutes once I located the plug underneath my dash. Etrailer had a video that even showed where to look on my vehicle. This unit is very easy to adjust and it is flawless so far. I had already purchased a controller in a local retailer's store but they didn't carry the adapter I needed in order to install the unit. had both units in stock and $20.00 less than my local store. I chose this unit because of the plug and play features and I know that if I want to change vehicles, I just need to purchase the corresponding adapter and I can easily transfer my Agility controller into my new vehicle. The shipping was fast and low cost. was my last stop during this project but they will be my first stop for my next trailer project!! 35377

Excellent. I hooked this Hopkins controller up with the specified harness and after plugging it into the Factory OEM plus on my Honda Ridgline, all I had to do was add a 20amp fuse as they don't put it in the Ridgeline from the factory, but the manual does list that. Worked like a champ! This proportional controller allows my Ridgeline with the trailer to feel as if there is nothing on the truck when I'm breaking. Seems as if there is no trailer connected as compared to when I have pulled with electronic braking where you never seem to get the settings just right. 54187

Fast service. Relatively easy to install (once you decide where to mount it). I haven't used it on my trailer yet, but I anticipate that it will work fine. I used the Plug in harness even tho' my Toyota Tacoma came with one, because I would rather not cut the wires from the controller and splice the wires from the harness. 110484

I need a Controller that can be removed when there is no need for it.

comment by: Noel W - 02/05/2014


Any of our controllers can be removed when not in use. Some are easier to remove than others. I have added links to controllers that have removable plugs for the harness and slide-in or snap-on style brackets so that no screws have to be removed to remove the controller.

Review from a similar Hopkins Agility in Brake Controller

I installed this in my '02 Toyota Tundra to pull a 20' hybrid camper. This truck doesn't have a plug and play option so used the wiring kit etrailer sells ETB7. Installed pretty easily. The way the unit connects to the mount is a little strange and difficult unless you have a lot of room on either side of the controller to fit a socket, which I did not. The red brake signal wire was too short to reach to brake switch wire in the truck, so had to splice in some extra. I've only pulled the trailer a few miles so far, but it actuated the brakes fine, and the override switch works well too. 178283

Ask the Experts about this Hopkins Brake Controller
Do you have a question about this Brake Controller?

  • Using a Multimeter to Troubleshoot Electric Drum Trailer Brake Magnets
  • I would check the magnets for wear before going on to test them with a meter. If the magnets show abnormal wear or if you can see the windings beginning to show through the friction surface of the magnet then they will need to be replaced. To further test your magnets, first make sure the trailer is not connected when performing this test. If the trailer is connected, you run the risk of shorting out the brake controller or various other electrical components. I attached an FAQ article...

  • ITBC on 2012 GMC Sierra Malfunctioning when Used on Some Trailers
  • I think you might be on the right track thinking that your ITBC is picking up on ground problems that an aftermarket brake controller would not. In my research, I found posts on several different forums indicating that the ITBCs are indeed very sensitive to any excess resistance. I found a few folks who recommend starting your tow vehicle, THEN plugging the trailer in. Apparently in some cases, this will help. As far as your ITBC being faulty, I can tell you that on the earlier ITBC...

  • Having the factory fuse is perfectly fine for an aftermarket brake controller. The benefit of a circuit breaker is that it can reset itself so you do not have to replace a fuse should it blow. So you are good to go with the 30 amp factory fuse installed. If the 14 gauge wire is output to the trailer brakes or even if it is 12 volt power to the trailer connector, 14 gauge is small. I would use 10 for 12 volt power to the connector and 12 for the brakes. However, gauge is determined by...

  • To install the Hopkins Brake Controller, # HM47294, on your 1998 Chevrolet 2500 truck you will need the Tow Ready T-One Wiring Harness, # 118315, and the Brake Controller 7 & 4 Way Installation Kit, # ETBC7.

  • Trailer Brakes Stay Engaged When Not Using Brakes or Override on Hopkins Agility Brake Controller
  • It sounds like you will need to set up the Hopkins Agility brake controller, # HM47294, as if you have just installed it. From time to time, settings can get changed and the controller can get knocked out of position and you might not notice. Double check to make sure the controller is within the +70 to -20 degree range, and that it is not tilted to the left or right. If it is, the internal inertia sensor inside may be incorrectly reading braking activity and send too much power to the...

  • Hopkins Agility Brake Controller Not Working On a 2003 Chevrolet Silverado
  • The Agility Trailer Brake Controller, item # HM47294, has a power indicator light. If this light is not on I would start by testing the wiring to the brake controller with a circuit tester, item # 3808 if needed. The black wire going into the brake controller should have power and the red wire should have power only when the brake pedal is pressed. The blue wire will only have power when the brake controller is activated and if the black wire has power on it. The white wire is the ground...

  • Which Brake Controller Should I use on a 2005 Chevrolet Tahoe with Factory Trailer Connector
  • The part you were looking at includes the harness for Ford vehicles. If you want to use the Hopkins Agility, the part number you would need is # HM47294 and # 47795. It has the plug-in harness for your 2005 Tahoe brake controller port. That port will only be active if your Tahoe came with a 7-Way trailer connector from the factory. I would strongly encourage you to get the Tekonsha Prodigy, part # 90185 and adapter part # 3015-P. It is our best selling brake controller and is one of...

  • The easiest way to install the Hopkins Impulse brake controller in your 2003 F350 would be to use their Brake Controller Wiring Adapter, part # HM47715.

The connector is located under the dash, to the right of the steering column as shown in the video I've linked for you.

  • E1/E3 Error Codes on Hopkins Impulse Brake Controller w/Trailer Connected to 2005 Chevy Avalanche
  • If you are getting the E1 Error code on the Hopkins Impulse Brake Controller # HM47294, that indicates that there is no trailer connected. Since you have a trailer connected and the code is still being displayed, this indicates a short on the Blue wire somewhere in the system. The E3 error code indicates that there is a short on the brake switch wire (red wire). Since the controller is throwing 2 error codes that both indicate shorts in the system, I am inclined to believe that the issue...

  • Troubleshooting Trailer Brakes Grabbing and then Operating Normally with Hopkins Agility Controller
  • An easy way to eliminate the brake controller from the equation would be to borrow a friends and install it on your setup and see if the problem persists. If it does, the problem is elsewhere, if not then you know the your Hopkins Agility Controller # HM47294 is at fault. If borrowing another brake controller is not an option you could use a circuit tester like our # 40376 and test the brake output circuit with your trailer connected and see if there is a spike in voltage when you initially...

  • Compatibility of OEM Brake Controller On Chevy Silverado 2500 with Electric Over Hydraulic Brakes
  • According to Dexter, their electric over hydraulic actuators should be compatible with the OE brake controllers, but in practice we find that is not always the case. We have found that the GM OE brake controller is not compatible with other electric over hydraulic actuators, so the fact that it is not working with your Silverado is not a huge surprise. Although I understand why you are not horribly excited by the idea of installing a controller, it is the only surefire way I know of...
