There should have been no need to remove the DB9 plug from the autopilot's Data Cable, as this plug is used to interface the S1000 to a NMEA 0183 source of GPS data ... see the diagram below.



The MFD will be interfaced to a white spur socket of the SeaTalkng backbone (should one be installed onboard) or of the SeaTalkng Converter via an appropriate length of SeaTalkng Spur Cable. The yellow and shield leads of the SeaTalk to SeaTalkng Cable supplied with the SeaTalk to SeaTalkng Converter Kit will be spliced to the yellow and black SeaTalk leads of the S1000 Data Cable respectively. The red SeaTalk leads of the SeaTalk to SeaTalkng Cable and S1000 Data Cable will not be used and will be insulated to prevent shorting. The SeaTalk to SeaTalkng Cable's yellow plug will then be connected to the SeaTalk to SeaTalkng Converter's yellow SeaTalk socket. If the SeaTalk to SeaTalkng Converter will not interfaced to a powered SeaTalkng backbone, then the SeaTalk to SeaTalkng Converter will need to be powered from a switched 12VDC power circuit using the SeaTalkng Power Cable packaged with the SeaTalk to SeaTalkng Converter. The SeaTalkng backbone must be properly terminated (i.e. one blue SeaTalkng Termination Plug inserted into the unused blue backbone socket at each end of the backbone).

As the S1000 is dependent upon GPS data, the a78 MFD (or GPS sensor which has been interfaced to the a78) must be receiving sufficient GPS satellite signal for it to acquire a GPS position FIX. Accordingly, the system should be tested under conditions permitting the a78 MFD to plot the vessel's position.
