Fitment guarantee and VIN verification

Every cable undergoes continuity testing of the copper conductor, inspection for overheating at the crimped eyelet terminals, and verification of the integrity of the factory heat shrink tubing.

Fitment tip: Power cables in Mild Hybrid systems must be selected strictly according to the part number and letter suffix (suffix N). Before purchase, we recommend comparing the number on the factory label or verifying compatibility using the vehicle's VIN.
