Curt 56222 Custom T-Connector Wiring Harness — 4-Way Flat — Kia Rondo / Kia Soul

Curt 56222 Custom T-Connector Wiring Harness — 4-Way Flat Output — Kia Rondo / Kia Soul

Vehicle-specific plug-and-play T-connector for select Kia Rondo and Kia Soul without LED tail lights. Plugs directly into the taillight assembly — no cutting, splicing, or soldering. Provides a standard 4-way flat output for trailer tail lights, brake lights, and turn signals. SMT circuitry, tail light converter included, rubber dust cover. Lifetime warranty.

✅ Vehicle Compatibility — Confirm Before Ordering

The Curt 56222 is designed for the following vehicles without LED tail lights:

Kia:
• Rondo — 2007 to 2012
• Soul — 2010 to 2019

This harness is vehicle-specific — verify your make, model, year, and tail light type (non-LED) match before ordering. It will not fit other vehicles or Kia Soul / Rondo models equipped with LED tail lights.

⚠️ Important — Not Compatible with LED Tail Lights

This harness is designed for Kia Rondo and Soul models with standard (non-LED) tail lights only. If your vehicle is equipped with LED tail lights, a different harness is required. Check your vehicle's tail light type before ordering.

Plug-and-Play Trailer Wiring for Your Kia — No Cutting, No Splicing

The Curt 56222 is a custom T-connector wiring harness that gives your Kia Rondo or Soul a standard 4-way flat trailer connector without touching a single wire. The harness uses OEM-compatible connectors to "T" into the vehicle's taillight assembly — unplug the existing taillight connectors, plug in the harness between them, and route the 4-way flat output to the rear of the vehicle. No cutting, no splicing, no soldering — just basic hand tools and the included instructions.

A built-in tail light converter handles the signal translation between the vehicle's separate brake and turn signal circuits and the standard combined trailer wiring format. SMT (surface mount technology) circuitry keeps the converter compact, generates less heat, and provides better long-term durability under towing vibration. A rubber dust cover protects the 4-way flat connector when no trailer is connected.

🔧 How Installation Works

1. Access the vehicle's taillight assembly

2. Unplug the existing OEM taillight connectors

No cutting, splicing, or soldering required. Basic hand tools only. Note: some reviewers note the cross-vehicle green wire has minimal slack — take care when routing.
