Grote 66864 10” Dual-Function Hard-Shell Connector Pigtail – Three-Wire S/T/T Lighting Plug

Heavy-Duty Dual-Function Connectivity

The Grote 66864 is a professional-grade 10-inch three-wire pigtail designed specifically for vehicles using hard-shell connector systems. Engineered for dual-function Stop/Tail/Turn (S/T/T) lamps, this pigtail provides a secure, snap-lock electrical bond that is built to withstand the high-vibration environment of heavy-duty trucks and trailers.

10-Inch Length for Simplified Routing

While listed technically as 5/6', the 10-inch length of the 66846 provides vital extra slack for technicians. This added length makes it much easier to route wiring through tight trailer cavities or around mounting brackets, ensuring that the connection remains stress-free and reducing the risk of wire fatigue or accidental disconnection.

Built for Long-Term Reliability

Electrical failure is a major cause of fleet downtime. The Grote 66864 is constructed with high-quality 18-gauge GPT wire, offering excellent flexibility and consistent conductivity. The hard-shell housing is precision-molded to seal out dirt and road debris, protecting the internal terminals and ensuring your safety signals remain bright and compliant.
