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 2020-2023 Buick Encore GX Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118829 (Part #TK118829) Drilling is required for installation. Basic hand tools are typically all you need.
The T-One® T-Connector is a vehicle wiring harness that provides a connection point for towing equipment. It integrates with your vehicle's taillight wiring on both driver and passenger sides, includes a black box module for signal processing, and provides a 4-flat connector for trailer hookup. The system requires a 15 amp fuse and battery connection to function.
The manual shows the Buick Encore GX as an application but does not provide a complete vehicle compatibility list. Contact the manufacturer or check the product listing to confirm fitment for your specific vehicle, year, and cab/bed configuration before purchasing.
Required tools are: trim panel remover, 10 mm socket and ratchet or 10 mm wrench, drill with 3/32" bit, 1/4" socket, wire crimpers, wire cutters, Phillips head screwdriver, and test probe. You will also need a test light or trailer to verify the installation after completion.
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, cable ties, and a 4-flat connector. The black box module houses the signal processing components.
Yes. You must disconnect the vehicle's negative (−) battery cable before connecting the fuse holder ring terminal to the positive (+) battery cable in step 8. Reconnect the negative cable only after the fuse holder connection is complete and before installing the 15 amp fuse 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.
On the driver side, locate the taillight wiring harness connector, separate it carefully without breaking the locking tabs, and insert the T-Connector end with the yellow wire between the vehicle connectors. Lock it in place. Route the green-wire connector down the threshold to the passenger side and repeat the process. Ensure all connectors are fully inserted with locking tabs engaged. Clean connector surfaces of dirt before insertion.
Yes. You must drill one 3/32" hole to secure the white ground wire. Locate a suitable grounding point on the vehicle's frame or crossmember near the connector. 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. Clean dirt and rustproofing from the area, then secure the white wire using the provided eyelet and screw.
The hole size is 3/32". Drill this hole in a suitable grounding point on the vehicle's frame or crossmember, not in the floor or bed. Clean the area of dirt and rustproofing before drilling.
The power wire is black, 12 gauge (12 ga.). It connects from the T-Connector box on the driver side, routes along the exterior frame or follows existing wiring along the thresholds into the engine compartment, and connects to the vehicle's battery. It must be routed to avoid hot pipes, heat shields, fuel tank, and pinch points.
The fuse rating is 15 amps. The yellow fuse holder is provided with the kit. Install the 15 amp fuse into the fuse holder after reconnecting the vehicle's negative battery cable (step 9). Do not exceed the product's amperage rating or the towing manufacturer's rating stated in your vehicle's owner's manual.
Disconnect the vehicle's negative (−) battery cable first. Locate the black 12 gauge power wire from the T-Connector box on the driver side. Attach the provided black 12 gauge wire. Route it along the exterior frame or follow existing wiring along thresholds into the engine compartment. After cutting 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 wire using the yellow butt connector provided. Reconnect the negative battery cable and install the 15 amp fuse.
The ground wire is white. Secure it to a suitable grounding point on the vehicle's frame or crossmember using the eyelet and screw provided in the kit. Drill a 3/32" hole at the grounding location, clean the area of dirt and rustproofing, and fasten the eyelet with the screw.
The yellow wire is on the T-Connector end installed on the driver side, and the green wire is on the T-Connector end installed on the passenger side. These wires integrate with the vehicle's taillight wiring harness to provide signal connections for the trailer lighting system. Both connectors must be fully inserted and locked in place for proper function.
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; choose a secure spot that does not interfere with vehicle operation or access.
Secure the remainder of the harness with the cable ties provided. Route the harness carefully to avoid any areas that would pinch, cut, or melt the wire. Be especially careful not to 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 it through the door and close the door carefully.
After all connections are complete, 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. All connections must be complete for the T-Connector to function properly. If the system does not work, verify that the 15 amp fuse is installed and all connectors are fully seated with locking tabs engaged.
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, the vehicle floor, or bed. When routing the black power wire, avoid hot pipes, heat shields, the fuel tank, and any pinch points. Do not exceed the product's amperage rating or the towing manufacturer's rating. Read and follow all warnings on the vehicle's battery before making battery connections.
Overloading circuits can cause fires. Do not exceed the stated product ratings or the towing manufacturer's rating (including the rating in your vehicle's owner's manual). Verify the amperage capacity before connecting any trailer or towing equipment.
After securing the harness with cable ties and mounting the black box module, replace both access panels, spare tire cover, cargo floor hatch, and cargo nets that were removed during installation. Verify that all connections are complete and test the system with a test light or trailer. Reset the vehicle's electrical system by temporarily removing the ignition key before the initial test.
The manual shows compatibility with the Buick Encore GX but does not provide a complete vehicle list. Verify fitment with the manufacturer or product listing before purchasing.
Yes, disconnect the negative battery cable before connecting the fuse holder to the positive terminal. Reconnect it only after the fuse holder connection is complete and before installing the 15 amp fuse.
The black power wire is 12 gauge (12 ga.). It connects from the T-Connector box to the vehicle's positive battery terminal via the fuse holder.
Do not exceed the product's amperage rating or the towing manufacturer's rating. Overloading circuits can cause fires. Always wear safety glasses during installation and verify what is behind surfaces before drilling.
Verify that all connections are complete and fully seated. Check that the 15 amp fuse is installed in the fuse holder. Ensure both T-Connector ends (yellow wire on driver side, green wire on passenger side) are fully inserted into the vehicle's taillight connectors with locking tabs engaged. Reset the vehicle's electrical system by temporarily removing the ignition key. If the system still does not work, test with a test light to verify power and signal at each connection point.
Ensure the vehicle's taillight wiring connectors are fully separated and clean of dirt before inserting the T-Connector ends. The locking tabs must be intact and not broken. Insert the T-Connector ends straight in until they are fully seated and the locking tabs click into place. If the locking tabs are damaged, the connectors may not secure properly.
Verify that the 15 amp fuse is installed in the yellow fuse holder. Check that the ring terminal is securely attached to the vehicle's positive (+) battery cable and that the negative (−) battery cable is reconnected. Ensure the yellow butt connector is fully seated between the fuse holder and the black 12 gauge wire. Use a test probe to verify power at the battery connection and along the wire route.
