Product Details

The Tekonsha 118890 T-One Connector is a vehicle-specific trailer wiring harness designed to provide a reliable electrical connection between your tow vehicle and trailer. This plug-and-play T-connector assembly eliminates the need for cutting or splicing into your vehicle's factory wiring, making installation straightforward and protecting your vehicle's electrical system.

Key Features:

  • Integrated ModuLite HD module with circuit protection prevents electrical damage to your vehicle
  • 4-way flat connector provides standard trailer lighting functions (tail, brake, turn signals, and ground)
  • T-connector design plugs directly into vehicle's existing harness for no-splice installation
  • Circuit-protected design safeguards against shorts and overloads
  • Engineered for vehicle-specific fitment for secure, factory-quality connections
  • Includes all necessary hardware for complete installation

This T-One connector system provides professional-grade trailer wiring integration while maintaining your vehicle's warranty and electrical integrity. The ModuLite HD module automatically isolates trailer lighting from vehicle circuits, ensuring safe operation and preventing feedback issues.

It was great! Good price, fast shipping.

The order itself was great, exactly what I needed for a great price. The shipping however was dismal. I had paid for 2 day shipping but received it after 7 days. After contacting customer service, the issue was resolved quickly and money refunded for the shipping charge. Great CS and place to shop.

Finding the part was super easy and simple. The only issue I really had was the delay in the shipping. I paid extra for faster shipping and it still took over a week to get to me. When I tried contacting them through the chat I never got any feedback after asking questions just a "let me check that for you" then chat ended. I finally decided to email and then I got a reply basically saying the same thing. Correct part did wind up showing up without tracking update(kept showing sent to warehouse).

Good
