Grote 66154 - 31' 2" Marker Light Jumper Harness, Two Slim-Line Males to Two Double Females

Extreme Reach and Versatile Power Distribution The Grote 66154 Jumper Harness is a professional-grade electrical solution designed for the most demanding trailer configurations. Measuring an impressive 31 feet 2 inches (374") in length, this jumper provides the maximum reach necessary for extra-long chassis trailers, ensuring that your marker and clearance lamps receive consistent, reliable power. This extended harness eliminates the need for unsafe wire splicing and multiple connections, providing a single, continuous run for superior electrical integrity.

Precision "Y-Split" Connectivity Engineered for "plug-and-play" efficiency, the 66154 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-capacity power splitter, allowing you to easily run multiple lamp leads from a single power source. It is the ideal choice for outfitting front upper clearance markers, side markers, or ID lamps directly from a front receptacle or main harness drop-out.

Industrial-Grade Durability for Heavy-Duty Fleets Built to withstand the punishing environment of long-haul trucking, the 66154 is constructed with rugged 14-gauge GPT wire. The factory-molded Slim-Line connectors offer 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, chemicals, and extreme temperatures, this harness helps reduce maintenance downtime and keeps your vehicle safe and FMVSS 108 compliant.

Key Features:

  • Extra-Long 31' 2" (374") Length: Maximum reach for versatile routing across the largest trailer frames.
  • Double Female Splitter: Dual .180" Slim-Line receptacles allow for easy power splitting to multiple lamps.
  • Slim-Line Design: Compact bullet terminals ensure a secure, low-profile fit in restricted spaces.
  • Heavy-Duty 14 GA Wire: Durable black GPT jacketed wire resists abrasion and environmental stress.
  • Universal Grote Compatibility: Designed for seamless integration with the Grote 66190 marker lamp harness series.
  • VMRS Coded: Listed under VMRS 034-004-023 for efficient fleet asset management.
