The only thing I'd recommend, is to make sure that GND stays connected.
Sorry to come back again, I have tried to attach a photo showing my proposed wiring. I would like to keep the NMEA, ST, and Pi separate in terms of having different bits powered up but not always all of it. So powered down the Pi would have ST data and GND but no power, and I'm assuming the SW 12v is sufficient for the ST input to work should both parts be powered.
Thank you
