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.

Features:

  • 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


Specs:

  • 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.

Universal Wiring Adapter for Hopkins Trailer Brake Controllers
part number: HM47685

Designed for applications that do not come equipped with a brake control wiring harness port from the factory, this adapter plugs into your Hopkins trailer brake controller at one end, and the other end splices into your vehicle's wiring.

Features:

  • Universal wiring adapter eases installation of your electric trailer brake controller
    • No need to wire brake controller directly to your vehicle
  • Wire end splices into your vehicle's wiring
    • Use on a vehicle that does not have a factory tow package or on one that has a brake control harness but is not equipped with a plug-in port
  • Connector end joins with the plug on your electric brake controller
    • Compatible with time-delayed and proportional brake controllers from Hopkins
    • Simple to plug and unplug control for removal
  • 2' Long, 12-gauge wires have protective covering to deter damage
  • 90-Day limited warranty


Installation of Hopkins Brake Controller 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. Usually when this is done, a port is installed at your dash so that you can easily plug in a brake controller. However, if no port is present, you will have to splice into your wiring.


With this universal adapter, you can install your Hopkins brake controller without having to wire the controller directly to your vehicle. If your vehicle has a factory tow package, just splice the pigtail end of the adapter into your vehicle's factory brake control harness wiring, and then plug the other end of the adapter into the controller. If your vehicle doesn't have a factory tow package, you'll have to hardwire the pigtail end of the adapter into your vehicle's wiring. Because only the adapter is hardwired to your vehicle, you can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.


If your vehicle is not equipped with a factory tow package, you will need to purchase additional equipment to ensure that the signals from your brake controller are sent to your trailer's brakes. We recommend etrailer.com's exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately).

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

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

etrailer.com made my product selection easy. They even showed the recommended wiring adapter without me having to search for it separately. This brake controller was easy to install and setup. This, in addition to a good price, made my purchase and installation easy. I would definitely choose them again for my camper and towing needs. 492582

Ask the Experts 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

  • Potential Causes for Continuous "Check Trailer Wiring" Warning Message on 2018 Chevy Silverado 2500
  • I appreciate your fighting spirit and your urge to get to the bottom of the issue behind the intermittent trailer connection warnings that appear on your 2018 Silverado that has a factory-installed trailer brake controller. But one of your comments caught my ear: "...they're barely, if at all, there..." I presume you are referring to the trailer brakes showing little or no actual stopping power; is this correct? The most obvious direction for my thinking on this is a simple connectivity

  • 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.

  • Brake Controller Recommendation for a 2006 Dodge Ram 2500
  • The Mopar brake controller is identical to the one they put in at the factory on certain Ram trucks. It is made specifically to fit the trucks it was designed for. In the aftermarket options there is nothing that is going to fit the same but they are also much, much less expensive and actually work better than factory integrated controllers. I recommend the P2, # 90885, because it is easy to set up and use and it is reliable. You will also need wiring harness # 3020-P to plug the controller
