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 Tekonsha 305000 fits a wide range of Nissan and Infiniti vehicles including: 2004-2013 Infiniti QX56, 2014-2020 Infiniti QX60, 2014-2021 Infiniti QX80, 2005-2025 Nissan Armada, 2005-2025 Nissan Frontier, 2013-2021 Nissan NV1500/NV2500/NV3500, 2005-2020 Nissan Pathfinder, 2004 Nissan Pathfinder Armada, 2004-2024 Nissan Titan, and 2005-2015 Nissan Xterra. Note that it does NOT fit the Titan XD model.
Unfortunately, the Tekonsha 305000 harness only covers 2004-2013 Infiniti QX56 models, so it won't work for your 2025. Infiniti actually discontinued the QX56 after 2013 and replaced it with the QX80, so you'd want to verify your exact model and look for the appropriate harness for your specific vehicle.
Yes, absolutely! The Tekonsha 305000 is specifically designed to fit 2004-2013 Infiniti QX56 models, so your 2009 is right in the sweet spot. This custom harness will plug directly into your vehicle's factory port and any Tekonsha brake controller for a clean, professional installation.
Installation of the Tekonsha 305000 is actually quite straightforward thanks to its Plug & Play design. You simply plug one end into your Tekonsha brake controller and the other into your vehicle's factory port - no cutting, splicing, or taping required. The harness comes with detailed vehicle-specific instructions, and basic hand tools are typically all you need to get the job done.
The Electric Trailer Brake Control Wiring Adapter is a connector that allows you to plug an aftermarket electric trailer brake controller into your vehicle's factory electric brake control harness. It acts as an interface between the vehicle's brake system and the brake controller, enabling you to control trailer brakes independently.
No. The adapter is designed for vehicles equipped with an OEM (factory) electric brake control harness. The harness is located underneath and to the left of the steering column, taped to another harness near the emergency brake pedal, and has a 6-pin connector. If your vehicle does not have this harness, the adapter will not be compatible.
The adapter itself may be compatible, but vehicles not equipped with an OEM trailer tow package may require additional fuses and relays to complete the output and battery feed circuits. These components are sold separately. You must consult your vehicle's owner's manual to determine the correct locations and specifications for these additional components.
The adapter supports a maximum of 6 brakes on 3 axles, with a maximum current draw of 18 amps. You must not exceed this limit or the towing manufacturer's rating, whichever is lower. Overloading the circuit can cause fires.
First, plug the brake control adapter into the mating receptacle on the backside of the brake control unit. Only after this connection is made should you plug the adapter into the vehicle's electric brake control harness connector. This sequence prevents accidental electrical contact during installation.
The harness is located underneath and to the left of the steering column. It is taped to another harness near the emergency brake pedal. The harness has a 6-pin connector that mates with the adapter connector.
Yes. After connecting the adapter, you must follow all installation instructions provided by the electric brake control manufacturer. You must also mount the brake control unit as directed by the manufacturer and perform all test procedures as instructed. The adapter is only one part of the complete installation.
The adapter fits vehicles with an OEM electric brake control harness (6-pin connector located under the steering column, left side, near the emergency brake pedal). Check your vehicle's owner's manual to confirm your vehicle has this harness.
Maximum 6 brakes on 3 axles (18 amps). Do not exceed this limit or your vehicle's towing manufacturer rating, whichever is lower. Overloading can cause fires.
Plug the adapter into the brake control unit first, then plug the adapter into the vehicle's 6-pin harness connector. Do not reverse this order.
Yes, you may need additional fuses and relays (sold separately) to complete the output and battery feed circuits. Consult your vehicle's owner's manual for the correct locations and specifications.
