Hi Moonlighter whilst on the subject I plan on not running analogue TRIM gauges or RPM gauges just run a C10 that are currently connected , can you let me know what i need to do to send the trim signal across the nmea 2000 network from the engine I will be changing the engine harness connection from the analogue to the digital digital plug on the engine side , and connect the interface cable directly directly behind the dash to the appropriate harness plug, there will be a Simrad to display all the engine data The engine is a suzuki df90A 2008/9 serial number 09002F-980299 .. thanks for the tips on Hull truth
