yamaha fuel gauge mystery wire

[swimdad]

Hello,

I recently had to dismantle my dash and I thought I had labeled each connection well but I didn't do as good of a job as I thought. In particular I have a loose unmarked green and white wire on the fuel gauge and I can't figure where the sucker goes. These are 2003 round multifunction models.. non-command variety.

does anyone have the schematics for these gauges?

thanks for the help.
Jerry
