Utilizes 18AWG copper core wire with a rated voltage of 300V, offering high current-carrying capacity and low resistance to stabilize light signal transmission, avoiding circuit overheating or insufficient brightness2. The cable is encased in a thickened PVC protective sheath, offering excellent waterproofing and abrasion resistance. It adapts to the demanding outdoor conditions of trailer use while safeguarding the core wires3. It reliably transmits signals for tail lights, brake lights, turn signals, and marker lights, assuring synchronized lighting signals for the trailer

• Core Function: The 4-way trailer plug serves as the standard interface connecting the electrical systems of the tow vehicle and trailer. It keeps stable transmission of signals for tail lights, brake lights, left/right turn signals, and running lights, providing a critical safeguard for driving safety
• High Conductivity: The internal wiring of the 4-flat trailer plug utilizes 18 AWG gauge wire rated for 300V, providing excellent current-carrying capacity. It reliably transmits the low-voltage power required for trailer lighting systems, effectively avoiding issues caused by unstable current or overload
• Durable and Resilient: The outer layer of the 4-pin trailer wiring harness is wrapped in thickened PVC material, forming a robust protective layer that delivers outstanding waterproofing, oil resistance, and abrasion resistance. This safeguards the internal wiring and extends its service life
• Clear Color Coding: The trailer light connector features 4 pins with standard color coding: Black connect to trailer green (right turn/brake), yellow connect to trailer brown (running light), red connect to yellow (left turn/brake), and white (ground). This clear color coding significantly reduces wiring installation errors
• Reliable Connection: The 4-wire trailer wire harness measures 59 inches in total length. Its precision-engineered male and female connectors provide smooth insertion and extraction, while the metal terminals deliver tight contact to effectively minimize loosening caused by vibrations
