It carries the six 14‑gauge circuits (brake lights, turn signals, tail lights, etc.) plus one heavier 12‑gauge wire typically used as the ground, all inside a black Duraflex® PVC jacket that stays flexible down to ‑40°F. You replace it when the trailer wiring is chafed, corroded, or shorted—it’s the main harness that runs from the nose box to the rear lights on most heavy‑duty semi‑trailers. Meets SAE J1128 for abrasion and chemical resistance.
