I'll just leave the white and green data lines unconnected. The regulators I chose can source 2 amps each, but to do so for very long will need good heat sinks on them. I'll screw them down directly to the aluminum dash for that.
Some gps's'ss's's need the data lines shorted or something so they don't go into mass storage mode.
