si4432 wireless receiver

Goodmorning,
I bought the si4432 wireless to make some projects. I linked it to arduino pro mini as described on this image "http://static.rcgroups.net/forums/attachments/4/0/8/5/8/3/a6555159-46-openlrs.jpg" (sorry if is coming from another forum).

Now, how to check if the wiring is correct?
Another thing, I want to control a relay linked to arduino with a 433mhz remote control, it is possible? And how?

This is the object I bought "http://www.ebay.it/itm/SI4432-470MHz-1000m-Wireless-Module-470M-433mhz-Wireless-Communication-Module-/200932667345"

Every informations will be appreciated.

Best regards
