Getting GPS input to Yamaha gauges

[JAGSARE1]

I need to get GPS data from my Furuno 1954C to the Yamaha gauges. What wire accomplishes this? There is a slot in the back of the Yamaha gauges for this =, I just don't know where to get the wire? Yamaha or BOE?

Been 4 years since i did this, but you need an extra cord....from Port 4 i think....to the ??White wire?? under the rubber plug on the yamaha gauges.

Check SIM's forums, he had a tutorial there.
