Fitment guarantee and VIN verification

Each harness undergoes an electrical circuit continuity test and a detailed inspection of the mechanical condition of the connectors, joint seals, and protective braiding.

Fitment tip: Steering rack wiring harnesses may differ in connector configuration depending on the presence of a four-wheel steering system (rear steering axle) or the type of dynamic steering rack. Before purchasing, we recommend comparing the OE number on the label of the old harness or verifying compatibility using the vehicle's VIN.
