I'm trying to figure out how to display my mpg on the fuel management gauge and if possible the 3210. I was told in a previous post FM + (blue) to Garmin port 2 (gray) because I am using port one for auto pilot. FM - (white) to garmin ground (black)
I don't see a white wire coming from the Yahama fuel management gauge. I do see a white with red stripe (i think). Am I missing something? Hopefully you can see the pic below and help me out? Also, while I have you.........where do you get those plastic bus bar nema connectors I saw on your vhf radio wiring. Thanks.......Danny

I haven't connected a 3210 to Yamaha fuel system. What I would do is call or email Yamaha tech support to get your answer. As you've seen NMEA color coding is not standard in the marine electronics industry. As for the buss bar you can get them at Radio Shack. Use dielectric grease on the wires and the buss bar after you make the connection. I'll see if I can get an answer from my Yamaha connection.

If anyone else has the same problem, I've solved it. All I had to do was unplug the wire that comes from the fuel management gauge and into the speed gauge, cut the end off at the speed gauge end and mate the white wire to the garmin blue or grey wire. Ended up being very simple to be so complicated. Also had to make sure the dip switches were in the right configuration.
