Good afternoon,


I tried to power my Yamaha Vmax engine on my lowi HDS-7 Carbon lowance unit, but got no response on the unit.


My engine came with the following
gauge


6Y7 Water Pressure meter
6Y8 Speed ​​Fuel gauge
6Y8 Tach
CommandLink ™ Junction Box


I bought the following cables:
Lowrance Yamaha Engine Interface Cable
NMEA 2000 Starter kit.


My question is should I buy anything else to do the engine readings on my lowrance hds-7carbon?
Where should I turn on the Yamaha lowrance engine interface cable?
