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 Tekonsha T-One T-Connector Harness, 4-Way Flat, w/Converter TK118413 (Part #TK118413) is designed to fit the 2006-2011 Hyundai Azera.
The Tekonsha T-One T-Connector Harness, 4-Way Flat, w/Converter TK118413 (Part #TK118413) fits the following vehicles: 2006-2011 Hyundai Azera; 2001-2007 Toyota Highlander. Always verify your specific year, make, and model before ordering.
The Tekonsha T-One T-Connector Harness, 4-Way Flat, w/Converter TK118413 (Part #TK118413) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The T-Connector is an electrical adapter that allows you to connect a trailer to your vehicle's existing taillight wiring. It intercepts the vehicle's taillight signals and routes them to a 4-flat connector for trailer use. The product includes a black box module, wiring harness with colour-coded ends (yellow for driver's side, green for passenger's side), double-sided tape, and cable ties.
The T-Connector (part number 118413-037) is designed for the Toyota Highlander and Hyundai Azera. Installation procedures differ slightly between these models: Highlander requires removal of the rear tailgate access panel, threshold, trunk floor panels and trays; Azera requires opening the trunk, removing the threshold panel, and partially removing the felt trunk liner on the driver's side.
You will need: 8mm, 10mm, and 13mm sockets with ratchet, or 8mm, 10mm, and 13mm wrenches; a test probe; and a trim panel remover. The T-Connector package includes double-sided tape and cable ties for mounting and securing the harness.
The manual does not specify whether battery disconnection is required. Consult your vehicle's owner's manual and the T-Connector instruction sheet for additional information on electrical safety precautions before beginning installation.
1. Locate the vehicle's taillight wiring harness on both driver and passenger sides. 2. Separate the existing taillight connectors carefully without breaking the locking tabs; ensure connector surfaces are clean and free of dirt. 3. On the driver's side, insert the T-Connector end with the yellow wire between the vehicle wiring connectors and lock into place, ensuring connectors are fully inserted with locking tabs engaged. 4. Route the T-Connector end with the green wire to the passenger's side and repeat step 3 with the green-wire end.
The T-Connector has two colour-coded ends: the yellow wire end connects to the driver's side taillight wiring, and the green wire end connects to the passenger's side taillight wiring. Each end must be inserted into the corresponding vehicle taillight connector on its respective side.
Locate the existing ground stud on the vehicle. Loosen the bolt on the stud, place the screw eyelet from the T-Connector harness onto the stud, and re-tighten the bolt. This completes the ground connection for the T-Connector.
Mount the T-Connector black box using the double-sided tape provided. Secure the remainder of the T-Connector harness with the cable ties provided. Be careful to avoid any areas that would cut or pinch the wire to prevent damage or rattling.
After completing all T-Connector connections and mounting, reposition the access panels, trays, and trunk floor panels, and reattach the threshold. Ensure all removed items are properly reinstalled.
All connections must be complete for the T-Connector to function properly. Test and verify the installation with a test light or by connecting an actual trailer once installed. This confirms that all wiring is correctly connected and the system is functioning.
Do not exceed the lower of your towing manufacturer's rating or these limits: maximum stop/turn light is 1 per side (2.1 amps); maximum tail lights is 4.2 amps. Overloading the circuit can cause fires. Consult your vehicle's owner's manual and instruction sheet for additional information.
Store the 4-flat connector in the trunk or rear cargo area when not in use.
Set aside all items removed during installation, being careful not to damage the parts. You will need to reattach these items (access panels, threshold, trunk floor panels, and trays) after the T-Connector installation is complete.
All connector surfaces must be clean and free of dirt to ensure proper electrical contact and function. Dirty connectors can prevent the T-Connector from working correctly and may cause intermittent electrical problems.
When inserting the T-Connector ends into the vehicle's taillight connectors, you must ensure the connectors are fully inserted and the locking tabs are engaged. This secures the connection and prevents the connectors from accidentally separating.
The T-Connector (118413-037) is designed for Toyota Highlander and Hyundai Azera models. Installation procedures vary by model. Consult the manual for your specific vehicle.
Do not exceed 1 stop/turn light per side (2.1 amps) or 4.2 amps for tail lights. Overloading can cause fires. Respect the lower of your towing manufacturer's rating or these limits.
Yellow wire connects to the driver's side; green wire connects to the passenger's side. Each end must be fully inserted into the corresponding taillight connector with locking tabs engaged.
