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 T-One® T-Connector is a trailer wiring harness that integrates with your vehicle's taillight wiring to provide power for trailer lights. It includes a black box module, connectors for both driver and passenger sides, a 4-flat connector for the trailer, and all necessary wiring and fasteners for installation.
The manual shows installation on a Volkswagen Atlas Cross Sport. The manual does not list other compatible vehicles. Contact the manufacturer or a fitment database to confirm compatibility with your specific vehicle make, model, and year.
Required tools are: trim panel remover, 10 mm socket and ratchet or 10 mm wrench, drill with 3/32" drill bit, 1/4" socket, wire crimpers, wire cutters, Phillips head screwdriver, and test probe.
The kit includes: two T-Connector ends (one with yellow wire for driver side, one with green wire for passenger side), a black 12 gauge power wire, a white ground wire with eyelet and screw, a yellow fuse holder with 15 amp fuse, a yellow butt connector, a black box module, cable ties, and a 4-flat connector for the trailer.
Yes. You must disconnect the vehicle's negative (−) battery cable before connecting the power wire to the positive battery terminal in step 8. Reconnect the negative cable after the fuse is installed in step 9.
You must temporarily remove the rear hatch, rear threshold plate, privacy screen, storage covers, and floor covering. Open the rear door and fold the rear seat forward. Then partially remove the rear interior trim panels on both driver and passenger sides. Set aside all removed items carefully to avoid damage.
Locate the vehicle's taillight wiring harness on both driver and passenger sides. Separate the connectors carefully without breaking the locking tabs. Ensure all connector surfaces are clean and free of dirt. On the driver's side, insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place. Route the connector with the green wire down the threshold to the passenger side and insert it between the vehicle wiring connectors, locking it in place. Verify that all connectors are fully inserted with locking tabs secured.
Yes. You must drill a 3/32" hole in the vehicle frame or crossmember to secure the white ground wire using the eyelet and screw provided. Do not drill into the vehicle floor or bed. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
Locate a suitable grounding point near the connector, such as the vehicle's frame or crossmember. Clean dirt and rustproofing from the area before drilling the 3/32" hole. Do not drill into the vehicle floor or bed.
Locate the black 12 gauge power wire from the T-Connector box on the driver's side. Attach the black 12 gauge wire provided. Route the black wire along the exterior frame or follow existing wiring along the thresholds into the engine compartment up to the battery. Avoid areas that may pinch or break the wire. If routing through a grommet and along the exterior, carefully avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
Yellow wire: driver-side T-Connector end. Green wire: passenger-side T-Connector end. Black 12 gauge wire: power wire from T-Connector box to battery positive terminal. White wire: ground wire to vehicle frame or crossmember.
Disconnect the vehicle's negative battery cable. Remove the fuse from the yellow fuse holder if not already removed. Cut the fuse holder wire and attach the ring terminal to the vehicle's positive battery cable. Connect the other end of the fuse holder to the black 12 gauge wire using the yellow butt connector provided. Reconnect the negative battery cable and install the 15 amp fuse into the fuse holder.
A 15 amp fuse is installed in the yellow fuse holder provided with the kit.
Locate a flat surface in an out-of-the-way place and mount the black box module to prevent damage or rattling.
Secure the remainder of the T-Connector harness with the cable ties provided to prevent damage or rattling. Be careful to avoid any areas that would pinch, cut, or melt the wire. Do not pinch the harness in the door latch.
Store the 4-flat connector in the rear cargo area when not in use. When in use, pull the 4-flat connector through the door and close the door. Be careful not to pinch the harness in the door latch.
All connections must be complete for the T-Connector to function properly. Test and verify 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.
Do not exceed the lower of the towing manufacturer rating (including in your vehicle owner's manual) or the specific amperage ratings stated on the product. Overloading circuits can cause fires. Refer to your vehicle's owner's manual and the product documentation for the exact amperage limit.
Always wear safety glasses and use all safety precautions during installation. Read and follow all warnings and cautions printed on the tow vehicle's battery. Verify what is behind any surface prior to drilling to avoid damage to the vehicle and personal injury. Do not drill into any exposed surfaces. Be careful not to pinch the harness in the door latch.
Replace both access panels, spare tire cover, cargo floor hatch, and cargo nets that were removed during installation. Test and verify the installation with a test light or trailer. For the initial test, reset the vehicle electrical system by temporarily removing the key from the ignition.
The manual shows installation on a Volkswagen Atlas Cross Sport. Compatibility with other vehicles is not specified in the manual. Contact the manufacturer or check a fitment database to confirm compatibility with your vehicle.
