Truck-Lite 88931 – 88 Series, 14 Plug, Rear, 55 in. License & Stop/Turn/Tail Harness, W/ S/T/T, M/C, Auxiliary, Tail Breakout, 14 Gauge, Male 7 Pole Plug, Right Angle PL-3, Female .180 Bullet Terminal
Streamline your trailer's rear lighting infrastructure with the severe-duty performance of the Truck-Lite 88931 88 Series 55-Inch Rear Stop/Turn/Tail (S/T/T) and License Plate Harness. Specifically engineered as an all-in-one electrical distribution center for commercial heavy-duty semi-trailers, box vans, flatbeds, and liquid tankers, this premium multi-plug sill harness provides a secure, factory-sealed wiring architecture. Measuring 55 inches in standard length, it acts as a centralized wiring system across the vehicle's rear sill, completely dropping the necessity for complex field-splicing, open terminal boxes, or vulnerable, taped raw wire paths.
What makes the Truck-Lite 88931 an indispensable rear chassis component is its highly organized wiring matrix. Featuring an expansive 14-plug layout, this system comes standard with dedicated, inline breakouts for Stop/Turn/Tail (S/T/T), Marker/Clearance (M/C), Auxiliary, and Tail circuits—including specialized auxiliary Red, Blue, and White drop-outs. Built around a high-conductivity 13-wire internal layout wrapped in a 14 AWG multi-conductor round PVC jacketed cable, it features a heavy-duty male 7-pole input plug on the primary feed side and feeds premium molded right-angle PL-3 lamp connectors and female .180 bullet terminals on the lamp ends. This plug-together design creates an airtight defense shield that completely isolates internal circuitry from corrosive road salts, freezing water, and continuous highway vibration.
