Grote 66080 ULTRA-BLUE-SEAL® (UBS) 7-Way Main Harness – 35' Long, Blunt Cut to 7-Way Female

The Foundation of a Corrosive-Proof Trailer Electrical System The Grote 66080 ULTRA-BLUE-SEAL® (UBS) Main Harness is engineered to eliminate the primary cause of trailer electrical failure: moisture and chemical corrosion. Spanning 35 feet (420 inches), this heavy-duty main harness serves as the central lifeline for your trailer's power delivery. Part of Grote’s premier UBS modular system, it is designed to keep your fleet moving by preventing the unplanned downtime caused by the harsh "highway soup" of salt, magnesium chloride, and environmental debris.

Maximum Protection with Sealed Modular Technology The 66080 features a specialized UBS 7-Way Female connector on one end and a blunt-cut finish on the other, allowing for flexible integration into your vehicle's nose box or receptacle. The harness is constructed with high-grade PVC-jacketed wiring that remains pliable and crack-resistant even in extreme sub-zero temperatures. By providing a totally sealed plug-in connection to your rear sill harness, it creates a moisture-tight barrier that protects critical copper conductors from the "wicking" effect of road spray.

Built for Heavy-Duty Performance Designed for compatibility with both LED and incandescent lighting systems, this 7-conductor harness features a robust gauge configuration—utilizing one 10-gauge wire for high-draw functions and six 12-gauge wires for standard signals. Whether you are outfitting a new 28-foot or 35-foot trailer or performing a full electrical overhaul, the Grote 66080 offers the "set-it-and-forget-it" reliability that professional operators and fleet managers demand.
