Grote 66161 - 24" Slim-Line Under Light Male to Slim-Line Double Female Jumper Harness

Reliable Power Expansion for Trailer Identification Lighting

The Grote 66161 Jumper Harness is a professional-grade wiring solution designed to provide seamless electrical access for trailer lighting systems. Measuring 2 feet (24 inches) in length, this jumper is engineered to function as a multiple identification (ID) lamp jumper or a front-to-rear marker lamp jumper. It allows fleet operators and owner-operators to expand their lighting arrays without the need for messy manual splicing, ensuring a clean and reliable electrical connection.

Precision "Plug-and-Play" Connectivity

This harness is built for high-performance power delivery, featuring a Slim-Line .180" Male Bullet on one end and a Double Slim-Line .180" Female Receptacle on the other. This "Y-split" configuration makes the 66161 an ideal choice for:

• Powering front upper clearance and marker lights directly from a front receptacle.
• Connecting front lower side markers.
• Accessing auxiliary drop-outs on rear sill harnesses.
• Integrating with the Grote 66190 marker lamp harness series.

Heavy-Duty Construction for the Long Haul

Built to withstand the punishing conditions of the heavy-duty trucking industry, the 66161 is constructed with high-quality 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. Its moisture-tight and vibration-proof design helps prevent the corrosion and electrical shorts common in trailer environments, keeping your vehicle compliant and reducing maintenance downtime.
