A totally proportional electric trailer brake control, the new Primus®IQ is self-leveling so no level adjustment is necessary. Utilizing the primary sensor technology from Prodigy®, the Primus®IQ now includes the Boost feature that gives users the ability to apply more initial trailer braking when towing heavier trailers. It works proportionally in reverse for backing into tough spots and includes a snap-in dash mounting clip and removable electrical connector that allows the unit to be quickly stored when not in use. You will appreciate the digital readout depicting a secure electrical connection, amount of voltage delivery to the trailer brakes and diagnostic features incorporated in the LED display.

Product Features

  • Brake controller activates trailer brakes in proportion to your vehicle's braking action for smooth braking every time
  • Automatically adjusts trailer's braking based on deceleration of tow vehicle
  • Activates immediately - no pausing like with time-delayed brake controllers
  • Automatic-leveling ability - internal sensor detects deceleration even if controller is not mounted flat
  • Position anywhere from 0 degrees (level) to 90 degrees in the vertical plane
  • 3 Boost levels let you adjust initial braking power and aggressiveness
  • Continual diagnostics check alerts you to any potential problems
  • Integrated safeguards protect your vehicle and trailer
  • Minimizes drain on car battery when not in use
  • Prevents trailer brakes from overheating by reducing power output to them during prolonged stops
  • Easy-to-read LED display
  • Built-in, slide-bar manual override
  • Quick-disconnect feature lets you easily remove and store the control when not in use
  • Replacement wiring harness (sold separately) and replacement bracket (6927 - sold separately) required to move the controller from one vehicle to another
  • Plug-in, vehicle-specific brake-control adapter (sold separately) can be used for certain applications to reduce installation time

Product Specifications

  • Application: trailers with up to 3 axles (6 brake assemblies)
  • Designed for use with electric brakes only
  • Dimensions: 4-3/8" wide x 5" long x 2-1/2" tall
  • Mounting: between 0 degrees (level) and 90 degrees in the vertical plane
  • Snap-in dash mounting clip and hardware included.
  • 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. Just set the initial power level, select a boost setting, and you're good to go.

As long as the Primus IQ controller is properly mounted 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.

     Proportional Braking System vs. Timed Braking System

           Time activated controls apply braking power at a fixed rate of time that is NOT proportional to the pressure applied to the brake pedal. They provide voltage output that increases to the gain setting over a period of time. Proportional controls determine the tow vehicle's rate of deceleration and apply the trailer brakes to match. They provide a smooth braking response in any stopping situation, with no need for adjustments.
