That'll work - I assume "cap" is the terminating ressistors?Thank you this was going to be my layout, I was going to grab power from my accessory Switch on my dash that powers my GPS unit only, as I only really need the engine data while running my MFD. Throw the book at me if I made a layout error
One bit of advice is plan the future of the NMEA 2000 system as it will no doubt expand.
