Grote 66153 - 7' Marker Light Jumper Harness, Two Slim-Line Males to Two Double Females

Reliable Power Distribution for Heavy-Duty Trailer Lighting

The Grote 66153 Jumper Harness is a high-performance electrical solution designed for the seamless expansion of trailer lighting systems. Measuring 7 feet (84 inches) in length, this jumper provides the ideal reach for standard-size trailers, ensuring your marker and clearance lamps receive constant, reliable power. Whether you are adding new lights or repairing an existing system, the 66153 offers a professional-grade connection that eliminates the need for messy manual splicing.

Precision "Plug-and-Play" Efficiency

Engineered for maximum versatility, this harness features a specialized configuration of Two Slim-Line .180" Male Bullets on one end and Two Double Slim-Line .180" Female Receptacles on the other. This "double-female" design acts as a high-quality power splitter, allowing you to easily run multiple lamp leads from a single power source. It is the perfect choice for outfitting front upper clearance markers or side marker lamps directly from a front receptacle or main harness drop-out.

Industrial-Grade Durability

Built to withstand the punishing environment of the open road, the 66153 is constructed with rugged 14-gauge GPT wire. The factory-molded Slim-Line connectors provide a compact, low-profile design that is easy to route through tight header rails or internal trailer channels while maintaining a moisture-tight, vibration-proof seal. Designed to resist road salt, moisture, and chemical corrosion, this Grote jumper harness helps reduce maintenance downtime and keeps your vehicle safe and FMVSS 108 compliant.
