Product Feature
(The 4-pin trailer wiring harness adapter features a wishbone design, widely suitable for rewiring trailers, allowing 2 yellow wires to run both the left and right tail lights. No need to splice other wires.)
Signal Synchronization: This wiring harness ensures that the trailer's taillights, brake lights, and turn signals synchronize with the corresponding signals from the towing vehicle. For example, when you activate the turn signal on the towing vehicle, the trailer's turn signals will flash simultaneously.

Multi-Functional Connection: This 4-pin 5-wire design supports multiple functions, including left turn signal, right turn signal, taillights (clearance lights), and brake lights. It include an additional wire for auxiliary functions, such as grounding.

Protective Function: The PVC Cable Jacket provides protection against wear and damage during towing and driving, ensuring the durability and reliability of the wiring harness.

Convenient Installation and Replacement: The harness is designed for easy installation and replacement, allowing users to maintain the trailer' s electrical system at home or in the garage without the need for professional tools or skills.

Power Supply: The harness not only transmits signals but also supplies power to the trailer's lights, ensuring they operate properly.

Interference Resistance and Durability: The harness features professional-grade wire cores that effectively reduce resistance and signal interference, ensuring clear and accurate signal transmission. The robust construction provides excellent durability, making it suitable for various weather and road conditions.
