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-Connector is a trailer wiring harness designed for the Chevy Volt LT Hatchback. It provides electrical connections between the vehicle's taillights and a 4-flat trailer connector, allowing you to tow a trailer with integrated lighting. The system includes a black control module, wiring harness with color-coded wires (yellow, brown, green, red, white, and black), connectors, a 15 amp fuse holder, and cable ties.
The T-Connector is designed specifically for the Chevy Volt LT Hatchback. The manual does not confirm compatibility with other Volt model years, trim levels, or body styles. Verify your vehicle matches this specification before purchasing.
You will need: trim panel remover, 10 mm socket and ratchet (or 10 mm wrench), drill with 3/32" drill bit, wire crimpers, wire cutters, Phillips head screwdriver, and a test probe. These tools are required to remove trim panels, disconnect battery, drill the ground hole, crimp wire connections, and test the installation.
The kit includes: a black control module, T-Connector harness with color-coded wires (yellow, brown, green, red, white, black 12 ga.), cable ties, a yellow fuse holder with 15 amp fuse, a yellow butt connector, an eyelet and screw for the ground wire, and a ring terminal. The 4-flat trailer connector end must be mounted in an accessible location using a bracket or electrical box (not included).
Yes. You must disconnect the vehicle's negative (-) battery cable before connecting the power wire to the battery. This is a required safety step performed in step 7. After all wiring connections are complete, you reconnect the negative battery cable and install the 15 amp fuse in step 10.
Yes. You must open the vehicle hatch and remove both the driver's side and passenger's side taillights to access the vehicle's wiring connectors. This is the first step of the installation process.
Mount the black control module underneath the vehicle on the driver's side, attached to the aluminum bumper support brace using the cable tie provided. The epoxy side of the module must point toward the ground to prevent water buildup. This is a critical orientation requirement.
On the driver's side, separate the vehicle's taillight wiring connectors carefully without breaking the locking tabs. Route the T-Connector end with yellow and brown wires upward between the bumper cover and rear body panel, exiting at the taillight pocket. Connect the yellow and brown wires to the matching vehicle connectors, ensuring all connectors lock into place and surfaces are clean and dirt-free. Repeat the same process on the passenger's side using the T-Connector end with green and red wires.
Route the green and red wires along the metal bumper from driver's side to passenger's side. Route the black 12 ga. power wire along the exterior frame or follow existing wiring along the thresholds into the engine compartment to the battery. Route all wires carefully to avoid hot pipes, heat shields, the fuel tank, and any points that may pinch or break the wire. Secure the harness with provided cable ties, avoiding areas that would pinch, cut, or melt the wire.
Yes. You must drill a 3/32" hole to create a grounding point for the white wire near the black control module. You can use an existing ground stud if available, or drill a new hole. 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. Clean dirt and rustproofing from the area after drilling.
The T-Connector uses the following wire colors: yellow and brown wires connect to the driver's side taillight; green and red wires connect to the passenger's side taillight; white wire is the ground connection; black 12 ga. wire is the power connection to the vehicle battery. The yellow fuse holder contains the 15 amp fuse for the power circuit.
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 it along the exterior frame or follow existing wiring along the thresholds into the engine compartment to the battery. After disconnecting the negative battery cable, cut the fuse holder wire, attach the ring terminal to the vehicle's positive (+) battery cable, and connect the other end of the fuse holder to the black 12 ga. wire using the yellow butt connector provided. Install the 15 amp fuse after reconnecting the negative battery cable.
The T-Connector uses a 15 amp fuse. The fuse is installed in the yellow fuse holder provided with the kit. The fuse must be installed in step 10 after all wiring connections are complete and the negative battery cable is reconnected.
Always wear safety glasses during installation. Read and follow all warnings and cautions on the vehicle battery before connecting the power wire. Do not exceed the product's amperage rating or the towing manufacturer's rating stated in your vehicle owner's manual. Verify what is behind any surface before drilling to avoid damage or injury. Do not route wires near hot pipes, heat shields, or the fuel tank. Ensure all connections are complete before testing. Overloading circuits can cause fires.
After all connections are complete and the 15 amp fuse is installed, test and verify the installation using a test light or by connecting an actual trailer. For the initial test, reset the vehicle's electrical system by temporarily removing the key from the ignition. This ensures all connections are functioning properly before towing.
Verify that all wiring connectors are locked into place and connector surfaces are clean and free of dirt. Ensure the black control module is mounted with the epoxy side facing the ground. Confirm that all wires are secured with cable ties and routed away from hot pipes, heat shields, fuel tank, and pinch points. Reinstall all taillights and plastic trim panels without pinching or cutting the wires. Test the installation with a test light or trailer to confirm proper function.
Mount the 4-flat connector end in an accessible location using a bracket or electrical box (not included). The manual does not specify a particular location, but it should be positioned where it is easy to connect and disconnect a trailer.
The T-Connector (118726-037) is designed for the Chevy Volt LT Hatchback only. Verify your vehicle matches this specification before purchasing.
