No Speed Reading

still no speed reading analog or digital. I traced the signal from airmar triducer and NL4-sr gps plug in to the connector under the front starboard seat where all the electronics are under the dash. From there there is cluster of cables going to medalion computer and power/ground buses.

Question; how does the speed/water temp signal gets to the BIG screen and the speedometer from the harness coming from the back of the boat? I am trying to connect directly from harness where i have the signal to the speedometer gauge on the dash. I think the BIG screen is a dummy screen and gets all the data from the medalion computer but the gauge should get its own wire somewhere. Any ideas how i can trouble shoot it? this is 2011 x25.
