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 (sold separately) 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 (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.

47294 Hopkins Agility Proportional Trailer Brake Control - Plug-In Simple





Hopkins Plug-In Simple Brake-Control Wiring Adapter - Ford
part number: HM47845

Designed for your vehicle with a factory tow package, this wiring harness plugs into the quick-connect harness located under your dashboard and into your Hopkins Agility, Impulse, Reliance or BrakeForce brake controller for easy installation.

Features:

  • 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


Tech Tip: The OEM plug in your vehicle is located under the dashboard to the right of the steering column, behind the black pocket in the dash.


This brake-control wiring adapter will simplify the installation of your Hopkins electric brake controller. Once the brake controller is installed, the harness then plugs into a port under the dash. Because your vehicle has a factory tow package, all the wires for the brake controller have already been run from the 7-way trailer connector at the back of the truck to the plug under the dash. If your vehicle does not have a factory 7-way, additional wiring will be necessary to complete installation.

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. Etrailer.com 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. Etrailer.com was my last stop during this project but they will be my first stop for my next trailer project!! 35377

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

This is a great product, and works perfectly for me. It is very easy to install; literally plug-and-play. I’m very satisfied w/ this unit. I had issue finding the factory installed brake control connecting cable on new 2016 Nissan Pathfinder Platinum. Had to take vehicle back to dealership and it took them 2 hours to locate and unwrap the connecting cable. I installed Hopkins Agility controller under dash above gas pedal (best location). Tight spot; used socket in hand to snug the 2 screws on right side of bracket. I remove the unit and secure the wiring under the dash (leaving installed bracket) when not towing. 315920

The item i clicked on was correct and the picture was accurate but i received this part for a newer truck which i can get in any store. I'm not paying one dime for return shipping. I found etrailer and thought it would be a good deal because i install hitches brake controllers and build trailers. But never again. No way in hell would i select the wrong part. Something happened on etrailers end not mine. 14bucks for return shipping in insane. When it's only a few bucks. But still etrail er should take care of it. I can order it on ebay cheaper with free shipping cheaper than the return price to etrailer. Be careful 508728

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

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

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

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

Do you have a question about this Brake Controller?


  • What is the AUX Power Pin for on a 7-Way Trailer Connector
  • Some trailers may need an auxiliary power source to power additional 12 volt items on the trailer but this isn't as common as you might think. Now instead of aux power reverse lights are more common on vehicle side trailer connectors (and still not used by all that many trailers). If your trailer does not need aux power and you don't want that circuit live at the connector you could remove that wire from the back of the 7-Way and cap it off with a wire nut, tape it up with electrical

  • 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

  • How to Set Up a Hopkins Agility Brake Controller Part # HM47294
  • The proper settings are determined by a host of variables including trailer weight, size of trailer brakes, vehicle weight, size of vehicle brakes, and cargo inside vehicle. You can get started by following the Setting Your Controller portion of the directions. If you do not have a copy of the directions, I have added a link to them below. In order to set up your brake controller, you need to connect the loaded trailer to the vehicle, and drive to a large open area, like an empty parking

  • Location of Brake Control Connector on 2006 Dodge Ram 2500
  • If your Ram is equipped with the tow package including the 7-way trailer connector on the rear bumper, the connector for installing your brake controller will be located above the white junction box behind and a bit above the emergency brake pedal. The connector is usually light blue in color. If the plug is present, you'd need the # HM47755 brake controller wiring to install the Hopkins Agility brake controller in your Ram. If your Ram was not equipped with the trailer connector, the

  • Brake Controller is Not Recognizing Trailer when Connected to Tow Vehicle
  • No the trailer does not have to have a battery in order for a brake controller to work. The first thing I recommend to determine the problem is to clean the vehicle and trailer side connectors. They should be clean and free of corrosion inside where the wires attach and outside on the pins. To test the brake controller you will need to sever the blue wire several inches from the back of the controller. Then use a circuit tester such as # 3808 to test the end of the blue wire coming out

  • E1 Error Code on a Hopkins Reliance Trailer Brake Controller
  • The E1 error code on the Reliance brake controller indicates that a trailer is not connected. If the trailer IS connected and you get the E1 code, a probable cause is a dirty trailer connector. Check the trailer connector on the trailer and on the vehicle. Clean out any dirt or corrosion. Corrosion can build up behind the connectors where the wires attach as well. It is also possible that you have blown the stop light fuse. Check the owners manual for the location of the stop light fuse

  • ITBC on 2012 GMC Sierra Malfunctioning when Used on Some Trailers

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

  • What does the SC Error Code Mean on a Hopkins Impulse Brake Controller
  • The error code SC means that the Impulse brake controller has detected a short circuit. To the best of my knowlege, there is not a CS error code on Hopkins brake controllers. You should check the brake controller connection under the dash to be sure it is wired correctly. The red wire should be inserted into slot A for 1999-2002 GM trucks or slot D for 2003 to 2006, and 2007 Classic body, GM trucks.

  • Troubleshooting Hopkins Agility Brake Controller Not Engaging Trailer Brakes with Brake Pedal
  • The first thing I would check on the Hopkins Agility Electric Brake Controller, # HM47294, is the red wire. On your 2001 Ford F-350, you can use the Hopkins Plug-in Simple Brake Wiring Adapter, # HM47715. This harness plugs into the brake controller and the other end plugs into a port under the dash of the truck. If you used this harness, or if you hardwired the brake controller, use a circuit tester like the Quickee # 3808 to probe the red wire on the back of the brake controller. When

  • The E1 error code on Hopkins brake controllers indicates that a trailer is not connected. If you do not have a trailer connected it will continue to display E1. If this happens when a trailer is connected then that could indicate a problem on the brake output circuit (Blue wire). The E2 error on your Hopkins brake controller indicates a short to the blue wire. The most likely culprit is a dirty or corroded vehicle/trailer connector and is causing the controller to work intermittently.

  • Factory Integrated Trailer Brake Controller Setup on a 2011 Chevy Silverado
  • To setup up the integrated brake controller that is on your 2011 Chevy Silverado you will need to first attach the 7-way from your trailer to the 7-way of your truck.

Next, you will want to set the correct trailer gain setting. To do this you will want to pull the trailer at about 25 MPH and

  • Adding an Auxiliary Power Circuit to a 7-Way Trailer Connector on a 2011 Chevy Silverado 1500
  • First, use a circuit tester like # 3808 if needed, to test the 7-Way trailer connector. The 12 volt circuit will be in the 1 oclock position. If the trailer side connector pin that corresponds with the 12 volt circuit is connected to the battery on the trailer, then you will not have to change or add anything. If it is not, you can either connect the battery to that circuit or use the auxiliary pin in the center. Again, use the circuit tester to test the center pin. It may be connected

  • No Trailer Brake Lights When Towed by 2002 Chevy Silverado 2500 with Hopkins Brake Controller
  • Since you have successfully tested your trailer with other tow vehicles you have isolated the problem to your 2002 Silverado. You do not mention whether this vehicle/trailer combination has ever worked together properly before. If so, the problem could be deteriorated connections or a bad ground. If not, the harness may have been incorrectly wired from the start. One solution is to just remove all the existing wiring and install a powered taillight converter such as part # 119190. I

  • Trailer Brakes do not Lock Up When Using Manual Override with Hopkins Agility Brake Controller
  • My recommendation for your situation would be to set up the brake controller as if it were new. The signal spike that you are seeing or split second hum that you are hearing when you press the brake pedal indicates that power is reaching the brakes, but since this is a proportional brake controller, the signal will not stay if the vehicle is not moving or decelerating. First, I recommend making sure the brakes on your trailer are adjusted properly since they are new. When adjusting

  • 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

  • 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.

  • Installing Brake Controller And Wiring Harness On 2015 Ford Flex Without Factory Tow Package
  • I have attached a drawing that shows how the wires are run for the # ETBC7 and brake controller wiring. There is no plug-in adapter available for a brake controller for your Flex with no factory towing package so it will be a hardwire installation. I called my contact at Tekonsha and they said the plug you sent the photo of is not the connector used for a brake controller. You will need to use the circuit tester that came with the # ETBC7 to test the wires on your Flex. The red wire
