Wiring diagram yamaha gauges

[N1NE1]

just bought a used boat with a Yamaha 200 hpdi and it has the Yamaha gauges for gas,oil,rpm,volt etc. The fuel gauge part stopped working and would like to know if there is a diagram for wiring the sending unit to gauge. Right now there is 2 wires coming off sending unit. I haven't traces them down yet,Trying to get some info first

Had the same problem with the same motor and it turned out to be the wires at the sending unit were corroded. Replaced the connectors and everything worked.
