Okay understood. So my plan now is to convert ST40 to NMEA2000 using parts E22158 and A06046 (to an NMEA2000 T connector), and leave the ST4000+ as standalone (the NMEA2000 instrument gauge I am looking at does not consume wind or heading data).

Are there any implications here for the SeaTalk power wiring? Or is it a straight connection?
