Yes, anode to the power supply and cathode towards the MPX board.

The LED is far more sensitive than the incandescent bulb, so it may tend to light up on noise even with no stereo signal. In that case, just decrease the value of the shunt resistor so that more current bypasses the LED and reduces its sensitivity.

Because the LED draws less current, the power supply will not drop as much as it did with the bulb (23v down to 15v) so you may only see a couple of volts drop.
