- Factory cable terminals matched to the alternator and vehicle installation.
- Properly selected conductor cross-section for starter loads.
- Insulation adapted for operation in the engine compartment.
- Compatibility with the factory mounting system in the Mercedes W204 C63.
Thanks to maintaining the original geometry of the harness, the cable is routed according to factory paths, which minimizes the risk of abrasion, overheating, and unwanted mechanical stress.
