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.

Yes, this T-Connector is designed for the Toyota C-HR. Installation involves removing the taillights and connecting to the vehicle's taillight wiring harness on both driver and passenger sides.
Trim panel remover, 10mm socket and ratchet (or 10mm wrench), drill with 3/32" bit, 1/4" socket, wire crimpers, wire cutters, Phillips head screwdriver, test probe, and Torx 10 driver.
Yes. You must disconnect the vehicle's negative (−) battery cable before connecting the power wire to the positive battery terminal. Reconnect the negative cable only after the fuse holder is installed and the 15 amp fuse is in place.
Yes. You must drill one 3/32" hole to secure the white ground wire to a suitable grounding point on the vehicle's frame or crossmember. Do not drill into the vehicle floor or bed, and verify what is behind the surface before drilling.
A 15 amp fuse must be installed in the yellow fuse holder provided. This fuse protects the power circuit and must be in place for the T-Connector to function properly.
Do not exceed the lower of the towing manufacturer's rating (including in your vehicle owner's manual) or the specific amperage ratings stated on the product. Overloading circuits can cause fires.
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. All connections must be complete for the T-Connector to function properly.
The T-Connector is a trailer wiring interface that connects to your vehicle's taillight wiring harness. It provides a connection point for a trailer's 4-flat connector, allowing your trailer lights to synchronize with your vehicle's brake, turn, and running lights.
No. You must remove both the driver and passenger side taillights to access the taillight wiring harness. Remove the two 10mm screws on each side, then carefully pull the taillight away from the vehicle without damaging the alignment pins.
Mount the black box underneath the vehicle behind the rear bumper fascia on the driver's side using the double-sided tape provided. Ensure the epoxy side of the module points toward the ground to prevent water buildup, and position it in a protected area where it cannot be damaged by road debris. Verify that the trailer's wire harness has adequate length to reach this point.
Ensure the unit is mounted in a protected area where it cannot be damaged by road debris or objects driven over. The epoxy side of the module must point toward the ground to prevent water buildup. Verify that the trailer's wire harness has adequate length to reach the mounting point.
The T-Connector has yellow wires (driver side taillight connection), green wires (passenger side taillight connection), white wire (ground), and black 12 ga. wire (power). The yellow fuse holder is also provided for the power circuit.
On the driver's side, fish the T-Connector end with yellow wires up between the bumper and vehicle body into the taillight pocket. Plug the yellow wire end between the mating plugs on the driver's side taillight socket and vehicle wiring harness. Repeat this process on the passenger's side with the green wire end, routing it underneath the bumper and up through the opening on the passenger side.

Route the green wire on the passenger side underneath the bumper and up through the opening. Avoid hot pipes, heat shields, the fuel tank, and any other points that may pinch or break the wire. Secure the remainder of the harness with the cable ties provided, being careful to avoid areas that would pinch, cut, or melt the wire.
Route the 4-flat harness underneath and to the center of the vehicle. Mount the 4-flat end in an accessible location with a bracket or electrical box (not included).
Drill a 3/32" hole to secure the white ground wire to the vehicle's frame or crossmember. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into the vehicle floor, bed, or any exposed surfaces.
No. Do not drill into the vehicle floor or bed. Locate a suitable grounding point on the vehicle's frame or crossmember instead.
Always wear safety glasses and use all safety precautions during installation. Read and follow all warnings and instructions included with the product and printed on the vehicle battery. Verify what is behind any surface before drilling. Do not drill into exposed surfaces. Ensure the T-Connector module is mounted in a protected area away from road debris.
