Grote 66170 - 2' Rear Tracking Lamp Jumper Harness, Standard .180" Male to Slim-Line Female

Reliable Adapter Solution for Modern Trailer Wiring

The Grote 66170 Jumper Harness is a high-quality electrical adapter designed to bridge the gap between standard wiring systems and modern, low-profile lighting. Measuring 2 feet (24 inches) in length, this jumper is specifically engineered as a Rear Tracking Lamp Jumper, providing the necessary flexibility to route power between lamp locations where straight-line wiring is not feasible. It is the ideal "plug-and-play" solution for maintenance, retrofits, and system upgrades.

Seamless Hybrid Connectivity

The 66170 features a specialized hybrid configuration, featuring a Standard .180" Male Bullet on the primary end and a Slim-Line .180" Female Receptacle on the secondary end. This design allows for a clean and secure link between traditional harness drop-outs and newer Slim-Line marker or signal lamps. By using this factory-molded adapter, you eliminate the need for unreliable manual splices, protecting your electrical system from the voltage drops and shorts common in custom-cut wiring.

Industrial-Grade Durability

Built for the rigors of heavy-duty trucking, this harness is constructed with premium 14-gauge GPT wire. The rugged black jacket provides excellent resistance to abrasion, oils, and road chemicals. The factory-molded connectors ensure a moisture-tight, vibration-proof seal, protecting the copper conductors from the road salt and humidity that cause corrosion. This jumper is a critical component for ensuring your fleet remains safe and fully compliant with FMVSS 108 lighting regulations.
