Trying to trace down the wiring is difficult and I do not have correct terms. I have an old seatalk backbone for the ST 60 instruments and a new one for the newer instruments. I have a seatalk junction bar to tie instruments together and a seatalk converter for the different backbones to communicate. Here is my best shot.

1. Seatalk (blue cable) from SPX 30 computer to Junction Bar.
2, Seatalk (other blue cable) from Junction Bar to Converter.
3. Seatalk (white)from Junction Bar to Autopilot Head
4. Seatalk (white) from Junction Bar to MFD

5. Seatalk (white but connected to the center Yellow on the Converter) to the ST60 Depth.
6. Red power from Converter to Instrument power source.
7. Seatalk (white) from Converter to I60 wind.
8. ST60 Depth connected to ST60 Speed via old seatalk cable.

Power to MFD from separate breaker.
Radar to MFD from direct cable connection.

Since just the Pilot is reading an error isn't the problem either in the Pilot Head or Course Computer?
