Grote 66135 - 7' Jumper Harness, Two Slim-Line Males to Two Double Females

High-Performance Power Distribution for Advanced Trailer Lighting

The Grote 66135 Jumper Harness is a specialized wiring solution designed for heavy-duty trailers requiring efficient power splitting for marker and auxiliary lighting. Measuring 7 feet (84") in length, this jumper provides a reliable, "plug-and-play" connection that eliminates the need for time-consuming manual splicing and protects the integrity of your vehicle's electrical system.

Precision Engineering and "Y-Split" Functionality

This harness features a unique configuration of Two Slim-Line .180" Male Bullets to Two Double Slim-Line .180" Female Receptacles. This design acts as a high-quality power splitter, allowing you to run multiple lamps from a single power source. It is specifically engineered for use with the Grote 66190 marker lamp harness series, making it the ideal choice for outfitting front upper clearance markers or front lower side markers directly from a front receptacle or main harness drop-out.

Industrial-Grade Durability

Built to survive the harsh conditions of the road, the 66135 is constructed with rugged 14-gauge GPT wire. The factory-molded Slim-Line connectors provide a low-profile, secure fit that is easy to route through tight header rails and internal trailer channels. By creating a moisture-tight seal at every connection point, this harness defends against road salt and chemical corrosion, ensuring your trailer stays visible and compliant.
