The conversion socket P125 comprises three connectors which receive/send the signals useful for the management of any additional systems.

In the detail, connector A:

• at pin 2 receives the D+ alternator charge negative signal via the connection with pin 4 of connector H of the Body Computer M001;

• at pin 3 receives the vehicle speed speedometer signal (VSO), supplied by the braking system control unit M051 via the connection with pin 49 of connector F of the Body Computer M001;

• from pins 9 and 10 communicates via the B-CAN line with the other network nodes;

    See E1050 CAN CONNECTION LINES

• at pin 14 receives the additional rear heater on signal in the under seat configuration (Combi version);

See E6012

• at pin 13 receives an ignition-operated supply (INT) through the line protected by fuse F49 of the Body Computer M001 (pin 6 of connector E).

On these versions pins 1, 4, 5, 6, 7, 8 and 12 of connector A are not connected because the vehicle has the original functions and connections in the electrical system. Pin 11 for the side marker lights is not connected because it is not available on versions designed for transporting people.

In the same way, connector B of P125 is not connected because on the versions in question the original system includes rear speakers.

Connector C for the conversion socket P125 receives a direct battery power supply at pin A protected by maxifuse F73 (TRASF) of the maxifuse box on the battery B099 (connector E), whilst at pin B it receives a power earth via the connection with the right front seat access board earth C098.
