This is really a cross post from the Honda forum but noone seems to be able to help there so I'm trying here.

I have a new fuel tank with sending unit, and also ordered a fuel gauge which I don't have already on board. I'd like to power this from the ignition SW so it only comes on when the switch is on. All power to my fuse panel is hot as long as my batteries are on. I have looked at the wiring diagram n the manual. I see a definition as P for pink on the bottom right corner of the diagram but no pink wire in the diagram itself. So where do I grab switched power from the control? I don't want to guess at this and take any voltage from a required use. Does anyone know what color wire I'm looking for?
I also have a trim gauge, battery gauge and tach allready on board. Could I pull power from the battery gauge feed?
Thanks.​

Power for the gauges is daisy-chained from one to the next, ultimately coming off the ignition switch. So just tap into the gauge next to the fuel gauge.
