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 2007-2010 Hyundai Elantra, 2006-2009 Hyundai Sonata, 2009-2010 KIA Optima Tekonsha Plug & Play T-Connector Adapter Trailer Wiring 118433 (Part #TK118433) Drilling is required for installation. Basic hand tools are typically all you need.
Yes, this T-Connector is designed for the Kia Elantra. The manual confirms fitment to this vehicle model. However, the manual does not specify which model years are compatible, so you should verify with the manufacturer or seller if you have a specific year in mind.
The T-Connector is a trailer wiring interface that taps into your vehicle's taillight wiring harness to provide trailer lighting connections. It allows you to connect a trailer's lighting system to your vehicle's electrical system without permanently modifying the factory wiring.
You will need: a trim panel remover, a drill with a 3/32" drill bit, a Phillips head screwdriver, and a test probe. You will also need rubbing alcohol and water to clean surfaces before mounting.
Yes. You must temporarily remove the rear threshold plate and partially remove the felt trunk liner behind the taillights to access the taillight wiring harnesses. These items are reinstalled at the end of installation.
Locate the vehicle's taillight wiring harness 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 wiring connectors and lock into place. Repeat on the passenger's side using the T-Connector end with the green wire. Ensure connectors are fully inserted with locking tabs in place.
Yes. You must drill a 3/32" hole to secure the white ground wire using the eyelet and screw provided. Before drilling, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into any exposed surfaces.
Mount the black box in the driver's side storage area. Clean a flat area using a mixture of rubbing alcohol and water, then secure the black box using the double-sided tape provided.
Route the 4-flat connector from below the threshold plate into the trunk and store it there when not in use.
Do not exceed the lower of your towing manufacturer's rating or these limits: maximum stop/turn light 1 per side (2.1 amps), maximum tail lights (5 amps). Overloading the circuit can cause fires. Refer to your vehicle's owner's manual and instruction sheet for additional information.
Test and verify the installation with a test light or by connecting a trailer once installed. 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.
The T-Connector uses yellow and green wires to connect to the vehicle's taillight wiring harnesses (yellow on the driver's side, green on the passenger's side). The white wire is the ground wire, which is secured to a grounding point using an eyelet and screw.
Locate a suitable grounding point near the connector. Clean dirt and rustproofing from the area using rubbing alcohol and water or similar cleaning method. Drill a 3/32" hole and secure the white wire using the eyelet and screw provided.
Route the T-Connector end with the yellow wire on the driver's side. Route the T-Connector end with the green wire to the passenger's side behind the panels and along the threshold. Be careful not to pinch or cut the wires when reinstalling the felt trunk liner, threshold, and other items.
Before drilling, verify what is behind any surface to avoid damage to the vehicle and/or personal injury. Do not drill into any exposed surfaces. This is critical to prevent hitting hidden wires, fuel lines, or structural components.
When separating the vehicle's taillight connector, be careful not to break the locking tabs. When inserting the T-Connector ends, be careful not to damage the locking tabs and ensure that connectors are fully inserted with locking tabs in place.
The T-Connector (part 118433-037) is designed for the Kia Elantra. Verify your specific model year with the manufacturer.
Trim panel remover, drill with 3/32" bit, Phillips head screwdriver, test probe, and rubbing alcohol with water for cleaning.
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.
Maximum stop/turn light: 1 per side (2.1 amps). Maximum tail lights: 5 amps. Do not exceed the lower of your towing manufacturer's rating or these limits.
Temporarily remove the rear threshold plate and partially remove the felt trunk liner behind the taillights. Reinstall them carefully at the end without pinching or cutting wires.
