Truck-Lite 50266 – 50 Series 451.5” Right Hand (RH) Side 1-Plug Turn/Tail Wiring Harness | Right Angle PL-3 to Ring Terminal, 14 Gauge
The Truck-Lite 50266 (50 Series) Right Hand (RH) Side Wiring Harness is an ultra-long, commercial-grade electrical assembly designed specifically for extended-length vehicles such as long-haul trailers, multi-axle tankers, and oversized transit buses. Spanning an impressive 451.5 inches (approximately 37.6 feet), this passenger-side harness delivers continuous, clean power from the front or midpoint of the chassis all the way to the rear passenger-side lighting array. Built with heavy-duty 14-gauge conductors, it is optimized to maintain electrical current integrity and combat voltage drop across exceptional distances.
Heavy-Duty Construction for Long-Haul Reliability
Longer wiring paths face increased exposure to environmental elements, rubbing, and vibration. The Truck-Lite 50266 solves this with a robust, factory-molded PVC round jacket that seals the internal copper lines from road spray, moisture, chemical washes, and winter de-icing salts. It is configured with a molded Right Angle PL-3 female connector on one end—providing a tight, low-profile, weatherproof seal directly to your standard tail lamp—and terminates in a rugged Ring Terminal on the opposite end for an unbreakable chassis ground connection.
