By using the original module, full compatibility with the electrical installation and the logic of the comfort systems in the specific Mercedes vehicle is maintained.

• appropriate connectors matched to the door wiring harness,
• proper communication with other control modules,
• consistent operation with original interior buttons and panels.

This approach minimizes the risk of compatibility issues, system operation errors, or the need for installation modifications.

This type of solution is particularly beneficial for premium class vehicles, where factory modules are designed for long-term operation and precise cooperation with other systems.
