oric_dan, I have looked at the datasheet you have sent me and it matches perfectly to the guidance that you have provided me with. Thank you for noticing and correcting the datasheet. Additionally, my shield was manufactured in 2010 and provides 3.3V and 5V pins so i think is the newer one.
Nonetheless, my question is still not being answered. My mistake for not making it clearer. Basically, I get which pins of the module are being used. What i don't get is which pins on the side of the shield (i believe they are referred as "jumpers" - JP1, JP2, JP3, JP4), are being used by the module.
The shield itself has holes next to each pin of the module. Do i need a wire to connect a pin of the module with a pin of a "jumper"? Or are the pins of the module directly connected with the pins of the "jumpers"?
