Grote 66162 - 12" Slim-Line Under Light Male to Slim-Line Female Jumper Harness – 14 GA

Precision Connectivity for Trailer Lighting Systems

The Grote 66162 Slim-Line Jumper Harness is a professional-grade electrical component designed to provide a reliable, "plug-and-play" bridge for your trailer's power delivery system. Measuring 12 inches (1 foot) in length, this jumper is engineered to function as a multiple ID lamp jumper or a front-to-rear marker lamp jumper. It is the perfect solution for fleets and owner-operators looking to maintain a secure electrical connection without the need for manual wire splicing.

Engineered for Professional Performance

This harness features a specialized Slim-Line .180" Male Bullet to Slim-Line .180" Female Receptacle configuration. This slim-profile design is specifically intended for modern trailer environments where space is at a premium, allowing for easy routing through tight header rails and internal channels. Whether you are accessing auxiliary drop-outs on a rear sill harness or outfitting front upper clearance markers, the 66162 ensures a moisture-tight, vibration-proof fit.

Industrial-Grade Durability

Built to withstand the punishing conditions of heavy-duty trucking, the 66162 is constructed with high-quality 14-gauge GPT wire. The factory-molded connectors protect against road salt, moisture, and chemical corrosion—the leading causes of electrical failure in trailer wiring. As part of Grote’s commitment to quality, this harness helps reduce maintenance downtime and ensures your vehicle remains compliant with federal lighting regulations.
