Grote 66150 - 16' Marker Light Jumper Harness, Two Slim-Line Males to Two Double Females

High-Performance Power Distribution for Extended Trailer Lighting

The Grote 66150 Jumper Harness is a professional-grade wiring solution designed to provide reliable, "plug-and-play" power delivery for marker and clearance lamps on heavy-duty trailers. Measuring 16 feet (192 inches) in length, this harness offers the extended reach necessary for bridging electrical gaps in larger trailer configurations, ensuring consistent signal performance across your vehicle frame without the need for unreliable manual splicing.

Precision "Y-Split" Connectivity

Engineered for seamless integration, the 66150 features a specialized configuration of Two Slim-Line .180" Male Bullets to Two Double Slim-Line .180" Female Receptacles. This "double-female" design acts as a high-quality power splitter, allowing for the connection of multiple marker lamps from a single power source. It is the ideal choice for outfitting clearance/marker lights directly from a front receptacle or main harness drop-out, providing a clean, moisture-tight electrical path.

Industrial-Grade Durability

Built to survive the punishing environment of the open road, this harness is constructed with high-quality 14-gauge GPT wire. The factory-molded Slim-Line connectors offer a compact profile for easy routing through tight header rails and internal trailer channels while maintaining a secure, vibration-proof fit. Designed to resist moisture, road salt, and chemical corrosion, the Grote 66150 helps reduce maintenance downtime and ensures your fleet stays safe and FMVSS 108 compliant.
