The wiring is pretty simple. P22 has 4 pins. Only the top 2 pins are needed. I think the top (Pin 1) is +12v I cant remember. Then Pin 2 is gnd - if you short the 2 pins you get the "skip signal"
For just the probe I wired the 2 wires from pin 1,2 and a attached it to a magnetic usb cable which connects to the probe. Some probes have a diode so if it doesnt work just reverse the 2 wires.
Here is my new MP3 probe which is much smoother and more consistent.
