Hopkins Agility Trailer Brake Controller - Plug In - 1 to 4 Axles - Proportional
part number: HM47294

Proportional brake controller mounts easily. Digital display indicates braking action of trailer. Fine-tune power adjustment has 5 levels so that you can set braking intensity to suit your towing needs.


  • Brake controller activates trailer brakes in proportion to your vehicle's braking action
    • Automatically adjusts trailer's braking based on deceleration of tow vehicle
    • Activates immediately - no pausing like with time-delayed brake controllers
  • Recommended mounting is between -20 degrees and 70 degrees
  • 5 Sensitivity levels let you adjust initial braking power and aggressiveness
  • Digital display is easy to read
  • Built-in, slide manual override lever
  • Plug-in, vehicle-specific brake-control adapter is required for installation


  • Application: trailers with up to 4 axles (8 brake assemblies)
    • Designed for use with electric or electric-over-hydraulic trailer brakes
  • Dimensions: 3" wide x 5" long x 1-1/4" tall
  • Limited lifetime warranty

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 is recommended to be mounted in your cab at an angle that is between -20 degrees and 70 degrees to make it easy 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 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.

part number: HM53075

  • Connects your Hopkins brake controller to your vehicle's factory tow package
    • 1 Plug is inserted into the back of your electric brake control
    • 1 Plug is inserted into the factory-installed port under your dashboard
  • Requires no cutting or splicing wires for installation - just plug and play
  • Works with Hopkins Plug-In Simple brake controllers (Agility, Impulse, Reliance, and BrakeForce)
  • 90-Day limited warranty

Installation of Hopkins Plug-In Simple Brake Control Wiring Adapter

To install your Hopkins 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.

Junction BoxBrake-Control Adapter Port

This adapter plugs into the port on your vehicle's built-in brake control wiring harness. The port is located in the wiring panel underneath the dash, to the left of the steering column, near the emergency brake pedal.

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.

I wasn't crazy about the idea of drilling holes in a brand new pickup, but getting over that was the hardest thing about installing my controller with the help of etrailer. plug the square end into the truck box, plug the rectangle end into the cotroller, mount controller box, put tools away. simple as that. will use them again in a heartbeat 156725

just fine. no complaints

2007 Chevrolet Silverado New Body

I usually receive good products from this store. This part, however, does not work. I plugged in the adapter according to the directions but when I tried to start the truck it would not start. I unplugged it and the truck started. It was causing the gushes not to work and the truck not to start unless I unplugged it. I would like to return the adapter plug. I matched up the year make and model and this plug was recommended. I would change it. Hopefully it did t damage anything on my truck. It was almost like it shorted the system out. 577612

I see that you ordered part # HM53075 for a 2007 Chevrolet Silverado New body. There is not a plug under the dash to plug in a brake controller adapter on a 2007 Chevrolet Silverado New body. The manufacturer did run wires from the back of the truck to the front under the dash. The wires from the back of the brake controller will need to be wired into the bundle of wires under the drivers side dash using butt connectors. The towing package wires may be labeled but it is a good idea to test them using a circuit tester part # 40376 before making any connections. I have attached a help article for installing a brake controller on a 2007 Chevrolet Silverado New body.

Just finished installing my Hopkins brake controller with the plug in wire harness for my Toyota Tacoma. Couldn't have been simpler. Took about 10 minutes. Took longer to find the factory connector which was part of the tow package on my truck. Nice product, also reached out to the tech department last night around 11pm and had the answer this morning at 7:30 am. That's great service, could have gotten it a little cheaper through another site, mainly because of free shipping but quality service like this is worth plenty. If I need any trailer accessories again etrailer will be who I call. 403544

First I would like to say etrailer is a great company to work with, they made contact with me by phone no an email to let me know that my parts were bcaked ordered and if I I was pressed for time they would send another like unit ASAP. Though I haven't had the opportunity to try the brake control the wire harness I ordered for my 2002 chevy silveroda and Control went in with no problems 540714

Do you have a question about this Trailer Brake Controller?

  • Using 7-Way 12V Power Circuit to Power Trailer LED Interior Lights
  • Yes, you certainly can use the 12V auxiliary power circuit on your 7-way wiring setup to power trailer lights. If you refer to the linked photo of a vehicle 7-way connector you will note that the 12V power circuit is carried on the contact at the 1:00 position as you look at the 7-way socket. This is noted by the yellow arrow. An easy way to access this 12V power circuit is to tap into it by using a junction box like # 277-000141. This box gives you a handy place to install a ring

  • Brake Controller for 2008 Dodge 2500 Diesel Towing Heavy 12000-lb Trailer
  • I recommend going with the Hopkins # HM47294 which is a proportional brake controller with 5 adjustable power levels to handle even the heaviest tow loads. This controller works on trailers with up to 4 axles, so you'll be able to use it on most other trailers that you may need to tow in the future. The easy to read display shows how much power is being supplied to the brakes and the controller can mount easily under your dash, so it's out of the way yet still easy to access the manual

  • Troubleshooting Brake Controller E2 Error Code
  • The Hopkins Agility Trailer Brake Controller # HM47294 you asked from is most likely too new to get that E2 code like the older models (it would be SC instead) according to my tech contact at Hopkins. With either the SC or the E2 code, it is showing a short in the blue output wire somewhere between the controller and the brake magnets. This can be due to a pinched or broken wire, a bad ground wire, or it could be from a bad magnet as you stated. I recommend using a circuit tester

  • Troubleshooting Brake Controller that Locks Up When Brakes Are Touches
  • Normally the issue is a short between the stop/turn light circuit and the brake output, but since you said you have a Hopkins Reliance (ironically the least reliable brake controller) there is an equal chance the controller is in need of replacing. Try putting both blinkers and see if the trailer brakes pulse in unison. If so, the issue is the wiring short. If not, then the issue is the controller is bad and needs to be replaced.
