More information on runout sensor

[dsancheznet]

Please provide a more detailed information on the runout sensor, since I do not quite understand how to wire it up in version 2.5 of the board. I own this sensor:

Which is apparently for an ender printer. Anyway, if I insert filament into the sensor, pins 1 and 3 get shorted. Where do I have to connect the pins... G + C or G + D or C + D or does it need to provide 3.3V or 5 V to the pins?

Best regards

connect it to pin G and C, no need to provide 3.3V or 5V.
