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 Tow Harness, 7-Way TK118273 (Part #TK118273) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the T-One T-Connector (part number 118273-037) is designed for Nissan Pathfinder and Infiniti QX60 vehicles. The manual confirms these as the compatible applications.
The kit includes a relay jumper harness with two small relays and one large relay, a tow plug harness with two blue relays, a 7-way socket, and cable ties for securing the harness. The 7-way socket bracket or electrical box is not included and must be sourced separately.
Required tools are: wire cutters, Phillips head screwdriver, test probe, trim panel puller, and a 10mm socket and ratchet or 10mm wrench. You will also need a test light or trailer to verify the installation after completion.
The subwoofer removal is conditional: if your vehicle is equipped with a rear subwoofer, you must carefully remove it by unscrewing the retainer bolt at the top of the speaker and disconnecting the speaker connector. If your vehicle does not have a subwoofer, this step is not applicable.
You must remove: the rear threshold, the cargo floor panel (moved to up position), the rear subwoofer (if equipped), the cargo assembly (three 10mm bolts and four retaining clips), the driver's side cargo loops (two 10mm bolts), and the driver's side carpeted trim piece (two retaining clips). All removed items must be carefully reinstalled after the harness is secured.
Using two small relays and one large relay, carefully insert each relay into the relay jumper harness. The terminals of each relay will match the configuration of the relay jumper harness end. Ensure that all relays are fully inserted with locking tabs in place. Do not use relays other than those included, as different relays can cause the unit to malfunction or damage the vehicle or trailer.
Open the hood and locate the relay box behind the driver's side headlight. Open the cover and insert the two blue relays into the open cavities. Ensure that the relays are fully inserted with locking tabs in place.
From underneath the vehicle, locate the tow plug harness and the vehicle tow plugs behind the rear bumper near the center of the vehicle. Remove the protective caps from the vehicle tow plugs and return them to the customer. Ensure all connector surfaces are clean and free of dirt. Connect the tow ends to the vehicle's mating connectors, being careful not to damage the locking tabs. Verify that connectors are fully inserted with locking tabs in place.
Plug the 7-way socket (provided) into the Trailer Tow Harness. Route the 7-way connector to the center of the vehicle. Mount the 7-way socket end in an accessible location using a bracket or electrical box (not included). Secure the remainder of the harness with the provided cable ties, being careful to avoid areas that would pinch, cut, or melt the wire.
On the driver's side, under the trim panel area, locate the jumper harness connectors. The plugs will mate into the two relay jumper harness connectors. Ensure that the connectors are fully inserted with locking tabs in place. Secure the remainder of the harness with the provided cable ties.
Removal sequence: (1) open rear hatch and move cargo floor panel up, (2) remove rear threshold, (3) remove subwoofer if equipped, (4) remove three 10mm bolts and four retaining clips from cargo area, fold rear seats forward, and rotate cargo assembly, (5) remove two 10mm bolts from driver's side cargo loops and two retaining clips from carpeted trim piece. Reinstallation: reverse the sequence, carefully reinstalling all plastic trim panels, threshold, storage covers, and floor covering without pinching or cutting wires.
Do not exceed the lower of your vehicle manufacturer's rating or these maximum amperage limits: stop/turn light (10 amps), tail lights (10 amps), backup (10 amps), power circuit (30 amps), and trailer brakes for 3 axles/6 brakes (20 amps). Overloading the circuit can cause fires. Consult your vehicle's owner's manual and instruction sheet for additional information.
Always wear safety glasses and use all safety precautions during installation. Read and follow all warnings and instructions included with the product. Read, understand, and follow all warnings printed on the tow vehicle's battery. Do not exceed the lower of the towing manufacturing rating or the specific amperage ratings stated on the product. Keep the instruction manual for future reference.
All connections must be complete for the T-One T-Connector to function properly. Test and verify the installation with a test light or trailer once installed. For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition.
Remove the protective caps from the vehicle tow plugs during installation and return them to the customer. Keep them in a safe place for future reference or if the tow plug harness needs to be disconnected.
Relays must be fully inserted with locking tabs in place to ensure proper electrical connection and function. Incomplete insertion can result in poor connections, malfunction of the T-One T-Connector, or potential damage to the vehicle or trailer.
All connector surfaces must be clean and free of dirt to ensure proper electrical contact and prevent corrosion or connection failures. Clean surfaces help maintain reliable signal transmission between the vehicle and trailer.
Secure the remainder of the harness with the cable ties provided. Be careful to avoid any areas that would pinch, cut, or melt the wire. When reinstalling interior panels, be careful not to pinch or cut the wires. Proper securing prevents damage, rattling, and potential electrical failures.
