Grote 66111 - Triple-Light ID Harness, 54" Universal Jumper – Slim-Line .180 Connectors

Optimized Power for Triple Identification Light Bars

The Grote 66111 Triple-Light ID Harness is a professional-grade wiring solution designed to power identification lamp bars on heavy-duty trailers. Measuring 54 inches (4' 6") in length, this universal jumper harness provides the necessary reach and flexibility to connect your center-mounted ID lights to the main electrical system. Engineered for high-performance fleets, the 66111 ensures your trailer remains compliant with federal lighting regulations while minimizing maintenance intervals.

Corrosion-Resistant ULTRA-BLUE-SEAL® Design

Electrical failures at the rear of the trailer are most often caused by moisture and chemical intrusion. As part of Grote’s premier ULTRA-BLUE-SEAL® (UBS) wiring system, this harness features factory-molded plugs that create a moisture-tight barrier. The Blue 14-gauge GPT wire is not only highly conductive but also color-coded for easy identification during installation or troubleshooting.

Secure Slim-Line Connectivity

The 66111 is designed for a precise "plug-and-play" fit, featuring Slim-Line .180" Male Bullet terminations at the power end and a Slim-Line .180" Female Receptacle. This slim-profile design allows for easier routing through tight header rails and internal trailer channels. By providing a secure, vibration-proof connection, Grote eliminates the flickering and short circuits common with inferior, non-molded pigtails.
