Multiplexer Wi-Fi


I'm trying to make a Wi-Fi network from the original electronic equipment on my SM year 2001. Can someone help me know where to get the NMEA 0183 signal from Hydra 2000?  on the back cover of the hydra 2000 there is no other outlet, except the connector that goes to the processor.  I don't have the connection box installed.
