Hi looking for any help w connecting the 3126B cat engines to the garmin 8612 chartplotter. The 8612 has direct connection for J1939. But from what I read is that to have both engines on one display need a bridge for NMEA 2000 and connect that to the garmin. So I looking to find what cables and connectors need to connect both engines to the chartplotter. Thank you for any help.
