ST60 with SeaTalk to SeaTalkng converter

[oceanharmony]

Hi,
I am new to the forum so hope I am going about this correctly. I have a pretty outdated raymarine setup: Rl70C chartplotter, St 60 instruments and ST6002 autopilot. The Raystar 120 GPS has now failed and I am trying to install a RS 130 GPS using the seatalk to seatalk ng converter. I am linking the new GPS to the white socket, the old seatalk signal to the yellow socket and the power cable to the other white socket. I think the blue sockets are supposed to be stoppered with the seatalk terminators. Please comment on the setup proposal.

Thank You,
John.
