2010 Chevrolet Express Van - Hopkins Agility Trailer Brake Controller - Plug In - 1 to 4 Axles - Proportional

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 Chevrolet Express Van'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


  • 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 Chevrolet Express Van, and the other end plugs into the controller - no hardwiring required.

See also's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your Chevrolet Express Van.

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

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

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.

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.

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...

  • 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...

  • Maybe try a different dealership. Clearly the problem is in the wiring of your truck since the problem is there even without a trailer connected. I would imagine since the wiring hasn't been changed and thats the only part of the system thats left to try the problem is there. It sounds like something is shorting out on the trailer wiring circuits and it needs to be found and fixed. While your at it I would check the wiring of your trailer though looking for any shorts and fix as necessary....

  • 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...

  • 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...

  • 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 Brake Lights Not Working on a 2003 Chevy Silverado 1500
  • Since the lights on the truck are working but the lights on the trailer are not, I am inclined to believe that the problem is on the trailer side but I do not want to rule out the truck just yet. First, I recommend testing the trailer connector on the truck side. You will need 2 things. First, you will need a circuit tester like # 3808 if you do not already have one. Second, you will need someone to sit in the truck to run the lights while you test the trailer connector. The brake lights...

  • Locating Brake Controller Port on 2000 Ford F-150 To Install Hopkins Brake Controller # HM47294
  • The factory brake controller plug should be located under the dash to the right of the steering column. It should be located towards the center of the dash and may be tucked up and out of the way behind some wiring. I have linked an FAQ Article that shows the location of the plug. You will need the Ford Adapter, part # HM47715, to plug into the brake controller harness and the Ford plug under the dash. If you have a factory 7-Way on your 2000 Ford F-150, installation is complete after...

  • Factory 30 Amp Fuse for Trailer Brake Control vs Auto Resetting Fuse on a Ford F-150
  • 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...

  • Where Does a Brake Controller Wiring Harness Install on a 2012 Nissan Armada
  • To install the Hopkins trailer brake controller wiring harness # HM47635 you will need to locate the factory harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. I have linked a video and some instructions on another harness that fits that should help. The Hopkins trailer brake controller wiring harness # HM47635 is compatible with Hopkins brand brake controllers that accept the plug, like the...

  • Troubleshooting Brake Controller that is Blowing Vehicle Fuse
  • Brake controllers can go bad, and honestly Hopkins controllers are more prone to shorting out than other controllers on the market. You can easily test the controller to determine if the problem you are having is with the wiring or the controller. 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 the Quickee Tester, part # 3808, you should...

  • 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. Your truck should automatically detect that a trailer is connected at this point. If not, press one of the gain buttons of the controller to bring up the current trailer gain setting that you have. 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...

  • 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...
