Fultyme RV 590-2010 5-Way Flat Trailer Connector Car Side 48 Inch

The Fultyme RV 590-2010 is an industry-standard 5-way flat trailer wiring connector designed for light-duty towing applications requiring an auxiliary circuit — ideal for surge brake lockout or back-up lamp functionality. This is the car-side (vehicle-side) connector, featuring a generous 48-inch wiring harness for flexible routing and installation behind the tow vehicle.

Key Features:

• 48-inch car-side harness for versatile routing and installation flexibility
• 16-gauge bonded wire in standard industry colors: green, yellow, brown, and white
• 16-gauge single blue wire for the auxiliary circuit (surge brake lockout or reverse lamp)
• Tin-plated .187 terminals for enhanced current capacity and long-term corrosion resistance
• Flexible molded PVC connectors for durability and resistance to weather and vibration
• 7.5 amp maximum load capacity suitable for standard trailer lighting circuits
• Includes detailed wiring instructions for straightforward DIY installation

This 5-way flat connector supports all standard trailer lighting functions — tail lights, brake lights, left and right turn signals, and ground — plus one dedicated auxiliary circuit for surge brake lockout systems or reverse lights. The color-coded bonded wire simplifies splicing, while the tin-plated terminals and molded PVC housing deliver reliable, weather-resistant performance mile after mile.
