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.

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.

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

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

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

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

Do you have a question about this Brake Controller?


  • 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

  • Locating the Brake Controller Connector on a 2017 Ford F-150 to Install the Hopkins # HM47294
  • The Hopkins Agility Trailer Brake Controller # HM47294 will install in your 2017 Ford F-150 by using the Plug-In Adapter # HM47845. The adapter will plug into the connector which is installed behind a side panel between your steering wheel and your radio. You will need to disconnect the connector from that side panel (which is where an OEM controller would normally sit) and bring it to the underside of your driver side dash for installation. I have attached a video of the Tekonsha Prodigy

  • 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. For a brake controller I would recommend the Prodigy

  • Hopkins Impulse Brake Controller Intermittently Locks Up Trailer Brakes
  • The Hopkins Impulse is a time-delay brake controller. That means that once you step on the brake pedal the controller will send back power to the brakes over a certain amount of time. With this controller there is no way to adjust that delay. It sounds like there is a loose connection somewhere or something is off inside the controller. Check the red wire connection and make a new connection as needed. Make sure the vehicle and trailer side connectors are clean and free of corrosion

  • Recommended Wire Gauge for Wiring Trailer Brakes
  • I recommend using at minimum a 12 gauge wire like # 12-1-1, but preferably 10 gauge wire like # 10-1-1. When you try to run 12v power for electric brakes through a thinner 14 gauge wire to power something like your brakes it overloads the wire and causes overheat. Once overloaded, the copper wires heat up so much that it could melt the insulation in the 14 gauge wire and end up causing a short.

  • Hopkins Brake Controller Shows Short Circuit Error Code
  • The weight of the trailer would not cause the SC error code on your brake controller. The SC error code indicates there is a short circuit which is an electrical problem. The most common cause of this is a dirty or corroded trailer connector. Make sure that the truck and trailer side connectors are clean and free of corrosion inside where the wires attach as well as on the pins. The brake magnets, or even just one magnet could indeed cause this issue as well. As could wiring to the magnets.

If you have your Hopkins Force hard-wired, the 12 volt wire and ground wire could be switched. It could have been the wiring pigtail plug-in adapter that caused the brake controller to start smoking.

  • Troubleshooting Hopkins Agility Brake Controller that shows SC Code
  • The Hopkins Agility is somewhat prone to shorting out so the problem is most likely the controller. Testing it will let you know if it is the problem or not. Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide. Using a circuit tester like part # PTW2993, you should get output to the controller side of the wire you severed. If the manual slide activates the trailer brake

  • There are some common things you can check to determine what is causing the poor braking performance. First, you do not want the trailer brakes to lock up and skid. You want them to be at a point just under that. The resistance of 12-1/4 inch by 3-3/8 inch brakes should be 3.2 Ohms. The amperage draw per magnet should be 3.0 amps.

  • 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

  • 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.

I would strongly encourage you to get the Tekonsha Prodigy, part # 90885 and adapter part # 3015-P. It is our best selling brake controller and is one of

  • Fuse Location for Brake Controller on a 2005 Chevy Tahoe
  • On your 2005 Chevy Tahoe, if using a Hopkins brake controller you would need connector # HM47795. If it is a Draw-Tite, Reese, or Tekonsha harness you would use # 3015-P. For a Curt controller you would use # C51352. For a Hayes controller you would need # HA81780-HBC. None of these harnesses come with a fuse. It is possible that you are referring to the factory brake controller wiring harness that is included with some vehicles. If that is the case then the fuse for the brake controller

  • 2008 Ford F-250 Will Not Start or Crank After Installing Hopkins Brake Controller
  • First let's make sure you are using the proper brake controller wiring harness for your 2008 Ford F-250. For a Hopkins brake controller you should be using # HM47855. It would not hurt to make sure that it is also plugged into the correct plug on your truck. I am fairly certain there is only one though but it never hurts to make sure. If your truck came with a brake controller pigtail from Ford and you hardwired the controller to it then the wire colors would not match up between the
