[CA] A75 GPS data to GX1500S VHF

Read through this closed thread by Chuck and have a couple questions:

"Using GPS data from a SeaTalkng/NMEA 2000 GPS source to supply a DSC VHF Radio"

My A75 plotter, I40 Wind, I40 Tri data and Evolution autopilot are all networked and functioning properly.

I have a Standard Horizon Quest-X GX1500S radio that was getting GPS data. It was wired in through a series of splicing, twists, frayed wires, etc that was done by a previous owner. I took it apart to do the SeaTalkng backbone properly for the above instruments.

Now I want to get the GPS data back into the VHF for the DSC feature and on the radio display.

I have the Seatalk cable pictured here - yellow connector, white/black cable, two exposed wires (red and yellow)

If I wire the red & yellow wires on the cable to the VHF NMEA inputs (positive to positive, negative to negative), can I just plug the yellow connector into a "T" at the end of the backbone, or does this need to go through the converter bus (two blue plugs, two white plugs, yellow in the middle)?

Also, what is the difference between these two kits:
