Hopkins Agility Trailer Brake Controller - Plug In - 1 to 4 Axles - Proportional
Hopkins Plug-in Simple Brake Wiring Adapter - GM

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

Proportional brake controller can be mounted within a 360-degree vertical range. 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
• Multiple mounting options
  • Position at any angle up or down in the vertical plane
    • 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 brakes only
• Dimensions: 3" wide x 5" long x 1-1/4" tall
• Mounting: 360-degree vertical plane operating range
• 5-Year limited 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 can be mounted anywhere within 360 degrees vertically, but it is recommended that it be mounted in your cab at an angle that is between -20 degrees and 70 degrees to make it easier to access.

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.
