It eliminates the need to rewire the trailer’s existing power harness when upgrading to Enhanced Easy‑Stop ABS, making retrofit jobs faster and less expensive. You replace it when converting a trailer from the legacy Easy‑Stop system or when following a retrofit kit like R955320/R955323. The cable meets original WABCO specifications and carries both power and signal connections safely.
