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, the 2013-2016 Buick Encore Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118588 (Part #TK118588) is designed to fit the 2013-2016 Buick Encore.
The 2013-2016 Buick Encore Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118588 (Part #TK118588) fits the following vehicles: 2013-2016 Buick Encore. Always verify your specific year, make, and model before ordering.
The 2013-2016 Buick Encore Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118588 (Part #TK118588) Drilling is required for installation. Basic hand tools are typically all you need.
The T-Connector is a trailer wiring harness designed for the Buick Encore. It provides a connection point for trailer lighting by tapping into the vehicle's existing taillight wiring. The system includes a black box-module, T-Connectors with colour-coded wires (yellow, green, white, black), a fuse holder, butt connectors, cable ties, and an eyelet with screw for grounding.
Yes, the T-Connector 118588-037 is designed for the Buick Encore. The manual does not specify trim level, model year, or cab/bed configuration restrictions, so compatibility with all Encore variants is assumed. However, verify fitment with the manufacturer or retailer if you have questions about your specific vehicle.
You will need: Trim Panel Remover, 10mm Socket & Ratchet or 10mm Wrench, Drill with 3/32" Drill Bit, 1/4" Socket, Wire Crimpers, Wire Cutters, Philips Head Screwdriver, and Test-probe. Safety glasses are also required.
The T-Connector kit includes: two T-Connectors with colour-coded wires (yellow and green), a black box-module, a black 12 ga. wire, a white wire with eyelet and screw for grounding, a yellow fuse holder with fuse, two yellow butt connectors, and cable ties for securing the harness.
Yes. Step 8 requires you to disconnect the vehicle's negative (−) battery cable before connecting the fuse holder to the positive (+) battery cable. This is a critical safety step.
You must open the rear tailgate and remove the threshold, trunk floor panels, and trays. On the driver's side, partially remove the lower interior trim panels to access the taillight wiring connectors. Be careful not to damage clips or break locking tabs when removing panels.
Beginning on the driver's side, separate the vehicle's wiring connectors carefully without breaking the locking tabs. Insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place. Ensure all connector surfaces are clean and free of dirt. Repeat this process on the passenger's side using the T-Connector with the green wire. Route the green-wire T-Connector below the threshold cover to the passenger's side taillight housing.
Yes. You must drill a 3/32" hole on the driver's side near the connectors to secure the white ground wire with the supplied 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.
Use a 3/32" drill bit to create the hole for the white ground wire eyelet on the driver's side near the connectors.
Locate a flat surface in an out-of-the-way place and mount the black box-module to prevent damage or rattling. The manual does not specify an exact location, so choose an accessible area away from moving parts, heat sources, and moisture.
From inside the vehicle, connect the black 12 ga. wire and the black 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 other points that may pinch or break the wire.
The T-Connector includes: yellow wire (connects to driver's side taillight connector), green wire (connects to passenger's side taillight connector), white wire (ground connection to vehicle frame), and black wire (power connection to vehicle battery via fuse holder).
Disconnect the vehicle's negative (−) battery cable first. Remove the fuse from the yellow fuse holder if not already removed. 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 supplied yellow butt connector. All connections must be complete for the T-Connector to function properly.
The black power wire is 12 ga. (12 gauge).
Do not exceed the lower of the vehicle manufacturer rating or: Maximum stop/turn light: 1 per side (4.2 amps); Maximum tail lights: 7.5 amps. Overloading the circuit can cause fires. Consult your vehicle's owner's manual for additional information.
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.
Secure the remainder of the T-Connector harness with the supplied cable ties to prevent damage or rattling. Be careful to avoid any areas that would pinch, cut, or melt the wire. After securing the harness, reinstall all plastic trim panels, threshold, storage covers, floor covering, and other items that were removed during installation, being careful not to pinch or cut the wires.
Store the 4-Flat connector in the trunk area when not in use.
Yes, the T-Connector 118588-037 is designed for the Buick Encore.
