Jammy J-5024-WH 25 ft 4-Way Flat Wishbone Trailer Wiring Harness with 30 in Ground

The Jammy J-5024-WH is a 25-foot, 4-way flat wishbone trailer wiring harness designed for reliable tow vehicle-to-trailer electrical connections. The wishbone (Y-splitter) configuration allows the harness to route cleanly from a single vehicle connector to both sides of the trailer, making it ideal for standard trailer lighting setups including running lights, brake lights, and turn signals.

Featuring a 30-inch ground lead, this harness provides a dedicated chassis ground connection to ensure consistent, corrosion-free electrical performance. The 4-way flat connector is the most common trailer wiring standard, compatible with a wide range of trailers and tow vehicles.

Key Features:

• 25-foot total length — provides ample reach for most trailer configurations
• Wishbone (Y-split) design — routes wiring neatly to both trailer sides from a single source
• 4-way flat connector — industry-standard plug for broad compatibility
• 30-inch ground lead — dedicated ground for stable, reliable electrical performance
• Durable wiring construction built to withstand outdoor and road exposure
• White jacket color (WH) for easy identification and clean installation

The Jammy J-5024-WH is a straightforward, professional-grade solution for trailer lighting wiring, well-suited for utility trailers, boat trailers, and cargo trailers requiring a complete harness run from front to rear.
