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 2012-2017 Buick Verano Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118564 (Part #TK118564) fits the following vehicles: 2012-2017 Buick Verano. Always verify your specific year, make, and model before ordering.
The 2012-2017 Buick Verano Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118564 (Part #TK118564) fits 2012-2017 Buick Verano models. The 2017 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the 2012-2017 Buick Verano Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118564 (Part #TK118564) is designed to fit the 2012-2017 Buick Verano.
The 2012-2017 Buick Verano Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118564 (Part #TK118564) Drilling is required for installation. Basic hand tools are typically all you need.
The T-Connector is a wiring harness that integrates with your vehicle's taillight wiring to provide trailer lighting connections. It includes a black box that mounts inside the vehicle, connector ends that tap into the factory taillight harness on both sides, a ground wire, battery connections, and a 4-flat connector for storing in the trunk when not in use.
Yes, these installation instructions are specifically for the Buick Verano. The T-Connector is designed to integrate with the Verano's taillight wiring harness and mounting points.
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 during installation.
The kit includes: two T-Connector ends (one with yellow wire for driver's side, one with green wire for passenger's side), a black box, a white ground wire with eyelet and screw, a yellow fuse holder with 10 amp fuse, yellow butt connectors, double-sided tape for mounting the black box, and cable ties for securing the harness.
Yes. You must disconnect the vehicle's negative (-) battery cable before connecting the fuse holder to the positive battery terminal. The negative cable is reconnected after the fuse is installed in step 8.
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 the driver and passenger sides.
Locate the taillight wiring harness connectors on both the driver and passenger sides. Separate the factory connector carefully without breaking the locking tabs. On the driver's side, insert the T-Connector end with the yellow wire between the vehicle connectors and lock into place. Route the green-wire end to the passenger's side and repeat. Ensure all connector surfaces are clean and connectors are fully inserted with locking tabs secured.
Yes. You must drill a 3/32" hole near the taillight connector to secure the white ground wire using the provided eyelet and screw. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
Drill a 3/32" hole. Clean dirt and rustproofing from the area first, then secure the white ground wire using the eyelet and screw provided.
From inside the vehicle, connect the black 12 ga. wire and red wire from the T-Connector black box using the supplied yellow butt connector. You have two routing options: (1) route the black wire through a grommet and along the exterior frame, or (2) follow the existing wiring along the thresholds into the engine compartment up to the battery. Either way, avoid areas that may pinch or break the wire, hot pipes, heat shields, and the fuel tank.
Disconnect the vehicle's negative battery cable. Remove the fuse from the yellow fuse holder if present. 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 10 amp fuse into the fuse holder.
Install a 10 amp fuse into the fuse holder. This fuse is provided with the kit.
Mount the black box near the center of the vehicle, below the trunk threshold. Clean a flat area using a mixture of rubbing alcohol and water, then secure the black box using the double-sided tape provided.
Use the cable ties provided to secure the remainder of the T-Connector harness. This prevents damage, rattling, and pinching or melting of the wire. Be careful to avoid any areas that would pinch, cut, or melt the wire.
Replace the carpet and any other clips or panels that were removed during installation, being careful not to cut or pinch the wires. Store the 4-flat connector in the trunk area when not in use.
All connections must be complete for the T-Connector to function properly. Test and verify the installation with a test light or trailer once installed. For the initial test, reset the vehicle's electrical system by temporarily removing the key from the ignition.
The manual does not specify the product's amperage rating. However, you must not exceed the lower of either the towing manufacturer's rating (including in your vehicle owner's manual) or the specific amperage ratings stated on the product itself. Check the product label for the exact amperage specification.
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 wires, avoid hot pipes, heat shields, the fuel tank, and any 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 amperage ratings, as overloading circuits can cause fires.
Store the 4-flat connector in the trunk area when not in use.
Yes, the T-Connector (part number 118564-037) is designed specifically for the Buick Verano.
Yes, disconnect the negative battery cable before connecting the fuse holder to the positive terminal. Reconnect it after installing the 10 amp fuse.
Yes, you must drill a 3/32" hole to secure the white ground wire. Verify what is behind the surface before drilling to avoid damage.
The T-Connector uses a 10 amp fuse, which is provided in the kit.
Verify that all connections are complete and secure. Check that: (1) the taillight connector ends are fully inserted with locking tabs in place on both sides, (2) the fuse holder is properly connected to both the positive battery terminal and the black 12 ga. wire, (3) the 10 amp fuse is installed in the fuse holder, (4) the ground wire is securely fastened, and (5) all butt connectors are properly crimped. Reset the vehicle's electrical system by temporarily removing the ignition key. Test with a test light or trailer to verify function.
