NMEA 2000 connection for Honda Outboard

[TDJ2591]

I'm looking to add a GPS/fish finder with NMEA which would allow it to display engine operating & performance data. Has anyone connected one of these to a Honda? Is all that's needed are the networking kit and the cable to the engine? If so, which connector on the engine does the cable plug in to?

I'm not having much luck finding any specifics on line or in the Honda repair manual.

Now I'm interested in this! Thanks for making me want to spend money!
