Note: All potentials refer to pin 15 (GND). In case the control unit is not fitted with the fan/vent adapter
kits X3514-68001, the DB15 connector that is located on the electronic controller (shown by the
figure 64) carries all the input and output signal to remote control the 305-IC system; all the signals
are detailed in the table below (ref.Table 5).
