The BRAKE-EVN electric brake controller offers top-notch trailer braking when you need it most. This superlative proportional brake controller utilizes patented braking sensor technology and advanced electronics to provide a smooth braking response in any stopping situation. The BRAKE-EVN has easy-to-use arrow buttons so you can effortlessly set the power output to your desired braking power, a boost feature that lets you apply up to three levels of additional braking power, especially when hauling heavier loads, and manual override to help you brake safely when an unexpected stop pops up. The BRAKE-EVN also has a digital LED display so you can monitor your settings and trailer braking activity, a power-save mode to reduce battery drain when not in use, and a compact design, making it easily accessible from the driver’s seat. The Tekonsha BRAKE-EVN trailer brake controller works with 1-4 axle trailers, has a Plug & Play feature that allows for quick and easy connection with your vehicle’s wiring, comes with all the mounting hardware needed for installation, and is backed by a five-year limited warranty.

Tekonsha is a leading manufacturer of electronic trailer brake controllers, pioneering the category in the 1970s. The lineup spans proportional units such as the Prodigy P3 and Prodigy iD, time-delayed controllers, the wireless Prodigy RF, plus vehicle-specific wiring harnesses, adapters and trailer brake components engineered for smooth, predictable stopping at any speed.
Tekonsha Engineering Company began in 1964 building RV steps and mirrors. Within a few years it had found its real calling, and by the 1970s Tekonsha was pioneering the manufacture of electronic trailer brake controllers, the product category that still defines the brand. More than half a century later it remains the reference name in trailer braking and is part of the Horizon Global group alongside Reese, Draw-Tite, Fulton, Bulldog and Wesbar.
A brake controller is the component that tells a trailer's electric brakes how hard to work and when, and getting that right is the difference between a controlled stop and a shove from behind. Tekonsha builds both major types. Proportional controllers use an internal accelerometer to sense how quickly the tow vehicle is slowing and apply trailer braking to match, so light braking stays light and hard braking is immediate. Time-delayed controllers ramp to a preset output over a fixed interval, a simpler and more economical approach that suits occasional towing.
The current brake controller range covers most of that ground. The Prodigy iD pairs with a phone through Tekonsha's EDGE technology for setup and monitoring, the P3 offers storable settings for multiple trailers and a trilingual colour LED display, the Prodigy P2 adds a dimmable display and boost mode for heavier loads, and the Voyager keeps operation simple and dependable. The Prodigy RF mounts to the trailer itself and controls wirelessly, which suits rental fleets and drivers who swap tow vehicles.
Installation is supported by vehicle-specific brake control harnesses that plug into a factory connector rather than requiring cut-and-splice wiring, along with mounting brackets and adapters. Matched controller bundles pair a unit with the correct harness. Products are tested to meet and often exceed published industry standards.

Yes, the 3024-037 is designed for Ram 1500, 2500, and 3500 vehicles. Your truck must have a factory electric brake control harness with a 4-pin connector located underneath the dash, right of the steering column. If your vehicle does not have this factory harness, this adapter will not work.
Yes, if you are installing part number 3024-P only, you must use additional kit 30235-P to ensure compliance with California regulations. Failure to use the additional kit may result in independent liability for the user.
No tools are required for installation of the 3024-037 adapter itself. However, you will need to follow the electric brake control manufacturer's installation instructions, which may require additional tools depending on the specific brake control unit being installed.
The electric brake control harness connector is located underneath the dash, right of the steering column. The harness will be taped to another harness. You are looking for a 4-pin connector that will mate with the adapter.
First, plug the brake control adapter into the mating receptacle on the backside of the brake control unit itself. Only after this connection is made, plug the adapter into the vehicle's electric brake control harness connector (the 4-pin connector located underneath the dash, right of the steering column). Then follow all brake control manufacturer's installation instructions.
Do not exceed the lower of your towing manufacturer's rating or 8 brakes (24 amps) maximum for 4 axles. Overloading the circuit can cause fires. Consult your vehicle's owner's manual and instruction sheet for additional information about your specific towing capacity.
Wear safety glasses and use all safety precautions during installation. Read and follow all vehicle warnings and installation instructions before beginning. Complete the installation per the electric brake control manufacturer's instructions and perform all test procedures as instructed by that manufacturer.
