Yamaha Fuel Management

[Tails Up]

Does anyone know where I can either download or have installation instructions faxed to me on a Yamaha Fuel Management Gauge. I purchased a used gauge and unfortunately it did not come with instructions. From the searches I have seen on this board it looks to be fairly simple however I have a few questions:

which side of the water seperator does the sensor get installed?

What are the two connectors at the end that is connected to the sensor for?

how can the unit be hooked up to a Lowrance 337C (it has the NMEA connector for Lowrance to Lowrance)?

Are the wires at the gauge color to color connections?

Thanks for the help.

The sensor gets mounted on the outlet side of the fuel-water separator, with the flow arrow pointed at the motor. The extra pair of connectors on the sensor end of the harness is for a water-in-fuel warning system on the factory Yamaha fuel/water separator, you won't find it on a Sierra or even a Racor. Yes the NMEA outlet wire can be connected to the NMEA input wire for your Lowrance 337. Yes the FMS harness and gauge wiring is color coded to work with all the other Yamaha harness wiring under the console.
