B258 garmin transducer Cut and join a furuno connector

[JuanLopez]

Hello.
I have a B258 garmin transducer with I am using with a garmin 721xs.
I would like to use this transducer with a furuno fcv 585, so I have to cut the garmin blue 8 pin connector and join the wires to a 10 pin furuno connector.
Where can I find the next information?
- Colors of the wires of the B258 garmin cable and its funcions
- The number of the pin of the garmin connector to witch the wires are joined
- The number of the pin and the function of each pin in a 10 pin furuno connector

I have been looking for at the garmin web, but I didn`t find this information.

Thank you very much

Juan

Airmar has wiring diagrams of the transducers. I normally get the Airmar part number off the transducer and then look it up on the Airmar website. The colors should match up color for color in most cases and as you say, you would just wire on a Furuno 10 pin pigtail (AIR-033-333). Garmin ties a couple of the grounds together that Furuno keeps separately to ensure noises isn't coupled but once you cut off the Garmin connector the wires should be there. If in any doubt, give me the airmar part number (normally will start out 41-) and I will dig into it further.
