    5V to LED power supply (+), 3V3 = to a 3.3V Pin from RPi
    GND to LED power supply (-), GND = to a GND Pin from RPi
    HV1 to LED Data In, LV1 = to Pin 19 from RPi
    HV2 to LED Clock In, LV2 = to Pin 23 from RPi

    In the most cases, yes.
    You should better use also a shielded cable, like an unused USB-Cable.
