Gas meter monitoring: pins and connections


I want to build a gas meter monitoring system.

After building the Emontx, and uploading the "Pulse counting only" firmware, from this page...

...I see that I have to connect a TSL257 optical sensor to the emontx board.

However, I don't understand exactly which pins, in the following picture... correspond to DATA, VCC and GND pins of the sensor, respectively.

Please, can you highlight, on the same pictures, the connections?

You use the 3.5 mm jack socket labelled "pulse", and you connect the sensor to the plug according to the diagram here.
