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 2018-2023 KIA Rio Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118793 (Part #TK118793) Drilling is required for installation. Basic hand tools are typically all you need.
The T-One® Connector is a taillight wiring integration module that allows a trailer to connect to a vehicle's existing taillight harness. It intercepts the vehicle's taillight wiring on both driver and passenger sides, integrating trailer brake and signal lights into the vehicle's electrical system. The connector includes a black box-module, wiring harness with yellow and green ends, a 15 amp fuse holder, and grounding hardware.
The manual shows installation on a Kia Rio Sedan. The connector is designed to work with vehicles that have a taillight wiring harness with connectors matching the T-One® Connector ends. Compatibility depends on your vehicle's taillight connector type and configuration. Consult the product fitment database or contact the manufacturer to confirm compatibility with your specific vehicle 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. These tools are needed for connector separation, drilling the grounding hole, wire routing, and electrical testing.
The kit includes: T-One® Connector ends with yellow and green wires, black 12 ga. power wire, white grounding wire with eyelet and screw, yellow fuse holder with 15 amp fuse, yellow butt connector, cable ties, and the black box-module. A 4-Flat connector is also mentioned for storage in the trunk when not in use.
Yes. Step 7 requires you to disconnect the vehicle's negative (−) battery cable before connecting the fuse holder to the positive battery terminal. After all connections are complete, you reconnect the negative battery cable in step 8 and install the 15 amp fuse.
Open the trunk and temporarily remove the rear threshold plate. Partially remove the felt trunk liner behind the taillights to access the taillight wiring harness on both driver and passenger sides. This provides access to the vehicle's taillight connectors where the T-One® Connector ends will be inserted.
On the driver's side, locate the taillight wiring harness connector and separate it carefully without breaking the locking tabs. Insert the T-One® Connector end with the yellow wire between the vehicle's wiring connectors and lock into place, ensuring connectors are fully inserted with locking tabs engaged. Route the green-wire end to the passenger's side behind panels and along the threshold, then plug it between the mating plugs on the passenger's side taillight socket and vehicle harness. Ensure all connector surfaces are clean and free of dirt before connecting.
Yes. You must drill a 3/32" hole to secure the white grounding wire. Locate a suitable grounding point near the connector on the vehicle's frame or crossmember (do not drill into the vehicle floor or bed). Clean dirt and rustproofing from the area, then drill the hole and secure the white wire using the eyelet and screw provided. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury.
Drill a 3/32" hole for the white grounding wire. This hole is drilled into a suitable grounding point on the vehicle's frame or crossmember, not into the floor or bed.
Locate the black 12 ga. power wire from the T-Connector box on the driver's side. Attach the black 12 ga. 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 vehicle exterior, carefully avoid hot pipes, heat shields, the fuel tank, and other points that may pinch or break the wire.
The T-One® Connector uses three wire colours: yellow (driver's side taillight connector end), green (passenger's side taillight connector end), and white (grounding wire). The black 12 ga. power wire is routed separately from the T-Connector box to the battery via a yellow fuse holder and yellow butt connector.
A 15 amp fuse is used. The fuse is installed in the yellow fuse holder provided with the kit. The fuse holder is connected between the black 12 ga. power wire and the vehicle's positive (+) battery terminal using a yellow butt connector.
After disconnecting 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 ga. wire using the yellow butt connector provided. Reconnect the negative battery cable and install the 15 amp fuse into the fuse holder.
Mount the black box-module on a flat surface in an out-of-the-way location to prevent damage or rattling. The exact location is not specified in the manual, but it should be secure and protected from impact.
Secure the remainder of the T-One® 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. After securing the harness, replace the carpet and any other clips or panels that were removed during installation, taking care not to cut or pinch the wires.
Always wear safety glasses during installation. Before drilling, verify what is behind any surface to avoid damage to the vehicle or personal injury. Do not drill into exposed surfaces. When routing the power wire, avoid hot pipes, heat shields, the fuel tank, and other points that may pinch or break the wire. Read and follow all warnings printed on the vehicle's battery. Do not exceed the product's stated amperage ratings or the towing manufacturer's rating, as overloading circuits can cause fires.
All connections must be complete for the T-One® 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. Use a test-probe to verify proper electrical continuity and function.
Store the 4-Flat connector in the trunk area when not in use.
Yes. Disconnect the negative battery cable before connecting the fuse holder to the positive terminal. Reconnect after all connections are complete and the 15 amp fuse is installed.
15 amp fuse, installed in the yellow fuse holder provided. The fuse connects the black 12 ga. power wire to the vehicle's positive battery terminal.
Do not exceed the product's amperage rating or the towing manufacturer's rating. Overloading circuits can cause fires. Wear safety glasses during installation and verify what is behind any surface before drilling.
The manual states that all connections must be complete for the T-One® Connector to function properly. Verify: (1) both connector ends are fully inserted with locking tabs engaged on driver and passenger sides, (2) the white grounding wire is securely fastened to the frame, (3) the fuse holder is properly connected to the vehicle's positive battery terminal with the ring terminal, (4) the black 12 ga. power wire is connected to the fuse holder via the yellow butt connector, (5) the 15 amp fuse is installed in the fuse holder, and (6) the negative battery cable is reconnected. Test with a test light or trailer and reset the vehicle electrical system by temporarily removing the ignition key.
