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 2020-2024 KIA Soul Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118813 (Part #TK118813) Drilling is required for installation. Basic hand tools are typically all you need.
The manual shows installation on a Kia Soul. The manual does not list other compatible vehicles. Contact the manufacturer or check the product packaging to confirm fitment for your specific vehicle make, model, and year before purchasing.
The kit includes: two T-Connector ends (one with yellow wire, one with green wire), a black box-module, a 4-flat connector end, white ground wire with eyelet and screw, black 12 ga. wire, red wire, yellow butt connectors, yellow fuse holder with 10 amp fuse, ring terminal, and cable ties. A bracket or electrical box for mounting the 4-flat end is not included.
You will need: a trim panel remover, a drill with a 3/32" drill bit, a Phillips head screwdriver, and a test probe. Safety glasses are also required.
Yes. You must disconnect the vehicle's negative (−) battery cable before connecting the fuse holder to the positive battery terminal. This is done in step 8. After all connections are complete, you reconnect the negative battery cable in step 9.
Yes. You must drill a 3/32" hole to secure the white ground wire using the eyelet and screw provided. The hole must be drilled near a suitable grounding point after cleaning dirt and rustproofing from the area. Do not drill into the vehicle floor, bed, or any exposed surfaces. Always verify what is behind any surface before drilling to avoid damage to the vehicle or personal injury.
1. Remove the four screws from each taillight housing and carefully pull the taillight away without damaging the alignment pins. 2. Locate the vehicle's taillight wiring harness connector on both driver and passenger sides. 3. On the driver's side, insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place, ensuring connectors are fully inserted with locking tabs engaged. 4. On the passenger's side, repeat with the T-Connector end containing the green wire. Ensure all connector surfaces are clean and free of dirt before connecting.
Route the harness containing the green wire and the 4-flat connector down the opening behind the taillight on the driver's side. Route the harness containing the green wire underneath the vehicle and up through the opening behind the passenger's side taillight. The 4-flat connector should be routed toward the center of the vehicle. Secure the remainder of the harness with the provided cable ties, being careful to avoid areas that would pinch, cut, or melt the wire.
Locate a suitable grounding point near the connector. Clean dirt and rustproofing from the area. Drill a 3/32" hole and secure the white wire using the eyelet and screw provided. Do not drill into the vehicle floor, bed, or any exposed surfaces.
From inside the vehicle, connect the black 12 ga. wire and the red wire from the T-Connector black box using the supplied yellow butt connector. Route the black wire either through a grommet and along the exterior frame, or follow the 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, avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire.
Disconnect the vehicle's negative (−) battery cable. Remove the fuse from the yellow fuse holder if not already removed. Cut the fuse holder wire, attach the ring terminal, and secure it 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. After all connections are complete, reconnect the negative battery cable and install the 10 amp fuse into the fuse holder.
The T-Connector uses a 10 amp fuse. The fuse is installed in the yellow fuse holder after all other connections are complete and the negative battery cable is reconnected.
Mount the black box-module on a flat surface in an out-of-the-way place to prevent damage or rattling. The location should be secure and protected from impact.
Mount the 4-flat end in an accessible location using a bracket or electrical box. A bracket or electrical box is not included with the kit and must be purchased separately.
All connections must be complete before testing. 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. This ensures all connections are functioning properly.
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. The manual references product ratings but does not list the specific amperage value. Check the product label or contact the manufacturer for the exact amperage rating.
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. Before drilling, verify what is behind any surface to avoid damage to the vehicle or personal injury. Do not drill into the vehicle floor, bed, or exposed surfaces. When routing wires, avoid hot pipes, heat shields, the fuel tank, or any points that may pinch or break the wire. Overloading circuits can cause fires—do not exceed stated product ratings.
You need to remove the taillight housing enough to access the wiring connector. Open the rear lift gate, remove four screws from each taillight, and carefully pull the taillight away from the vehicle without damaging the alignment pins. After connecting the T-Connector, reinstall the taillight housing, positioning the vehicle wiring harness between the housing and the vehicle body.
The manual confirms installation on a Kia Soul. For other vehicles, contact the manufacturer or check the product packaging to verify compatibility before purchasing.
