GPS to Fuel Management Guage?

[Salty Dog]

I was hoping to do a search for the info but I couldn't find the search function. I have a Magellan gps that has red, yellow, black and yellow wires from it. I would like to hook it up to my Yammie fuel management guage. Does anyone know the right way to do this?

The white wire on fuel management gauge needs to connected to NMEA output lead of GPS, but I'm not sure which wire is the output lead on the Magellan

Thanks for the reply.

The orange is the NMEA wire,black is ground, red is power and yellow is DGPS.

I think the Yamaha wires are red, white and black. Do I use al three or just the white to the orange and leave the rest?

Connect the Yamaha white wire wire to the magellan orange wire and and the rest are not used.
