Tekonsha trailer brake controller harnesses exist to make connecting your brake controller to your vehicle as easy as possible. These custom two-plug units are specifically designed to be used with any Tekonsha brake controller. The Plug & Play feature on the Tekonsha wiring harnesses makes them easy to install. Simply plug one end of the harness into the back of your desired Tekonsha brake controller and the other end into the port in your vehicle. No cutting, splicing, or taping required.
Each wiring harness is made up of four copper wires wrapped with a braided nylon thread to insulate the wires and protect them against nicks, punctures, and elevated temperatures. The four-pin Plug & Play connectors on each end of the harness are uniquely designed, with one end to fit each vehicle based on make and model year specifications, while the other end plugs easily into any Tekonsha brake controller.
Tekonsha trailer brake controller harnesses are custom designed, giving you plenty of wire to reach between where it is connected to the vehicle and where it connects to the brake controller without stretching or straining the wires. And because Tekonsha is the leader in wiring and electrical, you can relax knowing your connections will be safe and secure, so you can hit the road with confidence! With Tekonsha, Lifes a Journey. Stop Often.

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 3064-037 is an electric trailer brake control wiring adapter that connects an aftermarket brake controller to your vehicle's factory electric brake control harness. It allows you to control trailer brakes from your tow vehicle.
No tools are required for installation of the adapter itself. However, you will need to follow the installation instructions provided by your aftermarket brake controller manufacturer, which may require additional tools.
The manual does not specify whether the battery must be disconnected. However, it does require that the vehicle be off with the keys removed from the ignition before beginning installation. Consult your aftermarket brake controller manufacturer's instructions for battery disconnection requirements.
The electric brake control harness is located underneath the dash and to the left of the steering column. It is taped to another harness near the emergency brake pedal. It has a 14-pin connector that mates with the adapter.
Plug the 14-pin connector on the adapter into the vehicle's electric brake control harness connector, which is located underneath the dash and left of the steering column near the emergency brake pedal. Then follow all installation instructions provided by your brake control manufacturer.
