Its very straight foward, (even though your diagram is not)
*Pins 3 and 4 are the coil...
*Pin 1 is the common pin...
*Pins 2 and 5 are the switching pins..
No3, let me try to explain what I mean..
When you apply power the the coil, the relay switches so that pin 1 and 2or5, (I don't know which) are connected, when no power is applied to the relay, pin 1 will be connected to either pin 5or2, (the oppisite one the when power is connected)
I hope this helps..
