The SAM module in this version is designed as a component mounted within the battery power supply system, integrated with the fuse box. This solution:

• ensures organized placement of fuses responsible for the vehicle's main circuits,
• allows for quick service access to electrical protection,
• works with factory Mercedes diagnostic systems,
• reduces the risk of overheating and overloads through appropriately selected current paths.

By integrating control functions with the fuse section, the module supports stable operation of comfort systems, lighting, and other consumers that are powered through this part of the installation in the Mercedes W204.
