AutoVEI OBD2F-4-MN12 adapter

The OBD2F‑4‑MN12 adapter is a vehicle diagnostic/programming interface adapter used with AutoVEI diagnostic tools (such as the Truck Explorer series). It’s designed to connect the main diagnostic device (like the VEI V7/V8 unit) to a vehicle’s MAN‑style diagnostic port (MN12) – a specific heavy‑truck connector type used by MAN trucks.

This adapter is included as part of larger truck diagnostic & ECU programming kits from AutoVEI (e.g., Truck Explorer PRO25, Locksmith/Pro kits). It’s not typically sold separately as a standalone consumer item from mainstream stores, so you mostly see it bundled in professional diagnostic kits.
