5804C - Mercedes Benz 38-pin Mux
Used for vehicles produced from years 1992 to around 2001.
This connector is included with the 8704 software package.

Mercedes has a special 38 pin connector in the engine compartment.

The purpose of this connect is because each control module has its own pin used for diagnostics.

ProgRama offers this unique diagnostic adapter (5804C)for its ability to automatically connect
to any of the 38 pins to give the technician a fast effort free diagnostic session.

Even though some Mercedes have an OBD II connector, you must use the 38 pin diagnostic connector to get full vehicle diagnostics.
