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.

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.

The 2007-2007 GMC Sierra 1500 HD Tekonsha BRAKE-EVN Proportional Brake Controller for Trailers with 1 to 4 Axles Black 8508220 (Part #8508220 70176) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The adapter is designed for vehicles equipped with a black Electric Junction Box located underneath the dashboard, left of the steering column, just above the carpet. All vehicles with this factory provision have a location for the adapter, but not all have complete connections to the battery and wiring to the rear for electric trailer brakes. To confirm fitment, locate the Electric Junction Box and check for the mating connection point in the top row, second from the left. If you cannot locate this box or connection point, the adapter may not be compatible with your vehicle. Consult your vehicle's owner's manual or contact the manufacturer for confirmation.
The adapter (part number 18283-037) is a connector that plugs into your vehicle's factory Electric Junction Box to enable electric trailer brake control. It serves as the interface between your vehicle's electrical system and an electric brake control unit, allowing you to control trailer brakes from inside the vehicle. The adapter must be plugged into the mating receptacle on the backside of the brake control before attaching to the vehicle connector.
The black Electric Junction Box is located in the interior of the vehicle underneath the dashboard, left of the steering column, just above the carpet. You will need to remove the cover to access the mating connection point for electric trailer brakes, which is located in the top row, second from the left.
First, plug the brake control adapter into the mating receptacle on the backside of the brake control unit. Then, plug the adapter into the mating connection in the Electric Junction Box. This sequence ensures proper connection before the adapter is attached to the vehicle connector.
After plugging the brake control adapter into the mating connection in the Electric Junction Box, carefully probe the adapter with a circuit tester to verify that battery (+) power is supplied to it. This confirms the adapter is receiving power from the vehicle's electrical system.
If your vehicle has no power supply to or from the Electric Brake Control Adapter, you must use an Electric Brake Control Wiring Kit. This kit includes the necessary wires and components to route power from the vehicle's electrical system to the adapter. Follow the wiring kit installation instructions to route all wires to the wire locations provided, or follow the brake control manufacturer's instructions.
Open the vehicle's hood and locate the black Electrical Center Box on the driver's side. Remove the box lid and cover to expose the vehicle's brake control feed wire (blue). This will require temporary removal of the vehicle's support brace. Attach and route all wires as described in the wiring kit installation instructions.
In the same location as the brake control feed wire, locate the vehicle's battery (+) supply wire (red) in the black Electrical Center Box on the driver's side. Attach and route all wires as described in the wiring kit installation instructions. After installing the wiring kit, reinstall the Electrical Center Box cover, lid, and support brace.
Yes. An in-line fuse or circuit breaker is required for the Electric Brake Control Wiring Kit installation. This protects the circuit from overload and fire hazard.
After plugging the brake control adapter into the vehicle's electric brake control harness connector, follow all brake control manufacturer's installation instructions. Complete the installation per the electric brake control manufacturer's instructions, mount the unit as directed, and perform all test procedures as instructed by the brake control manufacturer.
Do not exceed the lower of your towing manufacturer's rating or the following: maximum 4 axles with 8 brakes (24 amps). Overloading the circuit can cause fires. Consult your vehicle's owner's manual and instruction sheet for additional information about your specific towing capacity.
Perform all test procedures as instructed by the electric brake control manufacturer. The manual does not specify the exact tests, so refer to your brake control unit's installation instructions for the complete testing procedure.
No. The adapter requires a factory black Electric Junction Box underneath the dashboard, left of the steering column. Not all vehicles have this provision or complete electrical connections for electric trailer brakes. Locate the junction box to confirm compatibility.
An in-line fuse or circuit breaker is required only if you are using an Electric Brake Control Wiring Kit to complete the installation. If your vehicle already has complete connections to the battery and wiring to the rear, no additional fuse is required for the adapter itself.
Plug the adapter into the backside of the brake control unit first, then plug it into the Electric Junction Box in your vehicle. Do not reverse this order.
Maximum 4 axles with 8 brakes (24 amps). Do not exceed this limit or your towing manufacturer's rating, whichever is lower, as overloading can cause fires.
Yes, if you are using an Electric Brake Control Wiring Kit, you must temporarily remove the vehicle's support brace to access the Electrical Center Box and the brake control feed wire (blue). Reinstall it after completing the wiring kit installation.
