[CA] e120 to RS130

I have acquired 2 e120s and and and a rs130 gps. The e120s are networked together with a DSM300 and work fine, although I am waiting for new transducers to arrive to test it out. I am quite willing to purchase everything I need to connect a SeaTalkNG backbone to the SeaTalk 2 network and I know what I need, but I would like to test the RS130 with the NMEA 0183 network as I have pigtails to fit and I cannot find consistent wiring diagrams. I have a fairly good idea what would work, I am concerned about damage.

RS130 GPS CableNMEA Cable on E120
Yellow to white
Green to Yellow (probably no data on this line)
Shield to Brown and Green to DC -ve
Shield floating if connected to e120 internally
Brown floating
Red to +12V

I would like to know if I am correct
