Grote 66133 - 10' 9" Marker Light Jumper Harness, Two Standard Males to Two Standard Females

Reliable Power Extension for Heavy-Duty Trailer Lighting The Grote 66133 Marker Light Jumper Harness is a professional-grade wiring solution designed to provide consistent, reliable power to your trailer's marker and clearance lamps. Measuring 10 feet 9 inches (129") in length, this jumper offers the ideal reach for bridging electrical gaps in standard trailer chassis, ensuring your vehicle remains safe, visible, and FMVSS 108 compliant.

Precision "Plug-and-Play" Connectivity Engineered for seamless integration, the 66133 features a Two Standard .180" Male Bullet to Two Standard .180" Female Receptacle configuration. This design allows for a secure, vibration-proof connection between power sources and lighting components without the need for unreliable manual splicing or heat-shrinking. It is specifically designed to work in conjunction with the Grote 66200 series when an intermediate turn signal is located on the upper rail, providing a clean and organized wiring layout.

Industrial-Grade Durability Built to withstand the punishing environment of the open road, this harness is constructed with high-quality 14-gauge GPT wire. The factory-molded connectors are designed to resist moisture, road salt, and chemical corrosion—the primary causes of trailer electrical failure. Whether you are performing a full system overhaul or a quick repair, the Grote 66133 provides the "set-it-and-forget-it" durability that fleet managers and owner-operators demand.

Key Features:

  • 10' 9" (129") Length: Provides ample reach for versatile routing along trailer rails and frames.
  • Standard .180" Terminals: Features two male bullets and two female receptacles for universal Grote system compatibility.
  • Specialized Application: Ideal for intermediate turn signals located on the upper rail when used with the 66200 series.
  • Heavy-Duty 14 GA Wire: Durable GPT jacketed wire ensures maximum conductivity and abrasion resistance.
  • Weather-Resistant Design: Factory-molded plugs protect copper conductors from the elements.
  • VMRS Coded: Listed under VMRS 034-004-023 for easy fleet maintenance tracking.
