Tekonsha T-One Trailer Wiring Harness with 4-Way Flat Output

Professional-grade, plug-and-play trailer wiring solution designed for seamless integration with your vehicle's factory electrical system.

Part Number: 118583 Fits 2014–2015 Kia Sorento

Overview

The Tekonsha T-One is a custom-fit vehicle wiring harness that adds a standard 4-way flat trailer connector to your vehicle. By utilizing factory-compatible plugs, this system connects directly into your vehicle’s existing wiring without the need for cutting, drilling, or splicing, ensuring a clean and reliable electrical connection for your towing needs.

R&P Service Insight

Trailer wiring is often the most vulnerable part of a tow setup. This T-One harness removes the "human error" of manual splicing.

  • OEM Integrity: Maintains factory warranty by avoiding wire modification.
  • ModuLite Tech: Protects your vehicle's sensitive computer systems from trailer surges.
  • Weatherproof: Includes a dedicated dust cap to prevent terminal corrosion.

R&P Knowledge Hub

Compatibility: Designed specifically for vehicles equipped with factory tow plugs. It uses T-connectors to "T" into the lighting circuit for seamless signal transfer.

Vehicle / System Fit: Primarily engineered for 2014–2015 Kia Sorento models (EX and LX trims). Always verify the presence of the matching factory port before purchase.

Installation Notes: While the signal connection is plug-and-play, this unit requires a direct 12V lead to the vehicle's battery to power the ModuLite module.

Performance Insight: Features the ModuLite HD module, which draws power directly from the battery rather than the taillight circuits to ensure full brightness and prevent system overload.

R&P Repair Insight

When troubleshooting trailer lighting issues, start with the basics to ensure a long-lasting installation.

  • Battery Lead: Ensure the power wire is fused and securely routed away from heat or moving parts.
  • Ground Connection: A solid ground to the vehicle frame is essential for the ModuLite module to function correctly.
  • Plug Maintenance: Periodically apply dielectric grease to the 4-way terminals to prevent oxidation.

Features

Custom Fit

Plug-and-play design connects directly to factory ports for a fast, tool-free interface with vehicle wiring.

Circuit Protection

Weather Resistant

Heavy-duty 16-gauge bonded wire and a protective dust cap keep the connector safe in harsh environments.
