Tekonsha T-One T-Connector Harness 4-Way Flat
Product description
This 4-way flat T-connector harness helps you add basic trailer wiring to compatible Chevrolet Trax models without cutting or splicing factory wires. It plugs directly into the vehicle's existing harness and offers a tidy, factory-like appearance while giving you the ability to power stop, turn and tail lights for a small trailer or cargo carrier.
Key Points
The harness installs by unplugging the vehicle's factory connector and inserting the T-Connector into the harness, so there is no splicing required. According to the manufacturer, the one-piece, weatherproof construction stores neatly in the cargo area or under the bumper when not in use. The kit includes a dust cap to protect the 4-flat plug and clear do-it-yourself instructions that do not call for special tools. ⚙️

Usage Recommendations

For a clean installation, park the vehicle on level ground and use the provided instructions to locate the factory rear harness connector. The harness is intended for basic lighting circuits only, so it will not carry power for brake controllers or powered accessories. Consider that heavier trailer loads or trailers with powered accessories may require a different wiring solution with higher amp ratings or a separate power feed. 🚗
Practical Tips
Store the harness in the cargo area or tucked under the rear bumper when not connected to your trailer to keep the plug protected and avoid corrosion. The ModuLite HD module included in the assembly provides upgraded circuit protection compared to older passive designs, which can help reduce the chance of blown fuses during typical towing use. 🔧.
