  3. Connect the +12V cable to the positive port of the Female DC Barrel Jack
  4. Connect the ground Black cable from the coin slot to the negative port of the Female DC Barrel Jack
  5. Connect the same ground Black cable to any of the ground pins on the Raspberry Pi (Pin6, Pin9, Pin14, Pin20, Pin25, Pin30, Pin34, Pin 39)
  6. Connect the Raspberry Pi 5V(Pin2) to Relay VCC Port (This is +5V)
  7. Connect the Raspberry Pi GPIO3(Pin5) to Relay IN port (Signal Out)
  8. Connect the Raspberry Pi only 1 ground pin (Pin6, Pin9, Pin14, Pin20, Pin25, Pin30, Pin34, Pin 39) to Relay GND port (Ground)
