(DG) Instrument upgrade - system diagram

I'm replacing my old ST-50 instruments and my old autopilot with a Seatalkng-based network. I know I have to first connect the i70 to the network, and then connect the i60 wind instrument to the i70 with a Seatalkng spur cable.
Would you please review the attached system diagram?
