Fingerprint with Integrated proximity capacitive sensor | instalationProblem

Hi, i am new to arduino. I am trying to build an attendance system for my university project.
I bought this fingerprint scanner and there are 6 wires to be connected ... it did not come with no installation manual... I have been googling for some time now, and now I know how to make it work but only with 4 wires, I dont know how to use the other 2 which are supposed to make proximity sensors work ... I dont want to go around and try things because electronics is not my thing. I am more of a programming guy ...

Any help is appreciated.

The installation manual is conveniently linked to directly from the Amazon product page link you gave.
I don't see a mention of "proximity sensor" in either the Amazon page or the manufacturer's manual page - but you could post a comment there, it looks like the manufacturer actually monitors their page and responds to messages.
