Don't be embarassed, asking is the road to knowledge, silence is the way to ignorance ^^
There are two types of automotive relays, respectively 5 and 4 pins relays.
When the coil is energized, it creates an electromagnetic field and it makes the "needle" (connected to pin #30) moving, closing (making contact) the circuit between pins #30 and #87.
On 5 pins relays, pins #30 and #87A are connected when the coil isn't energized, then disconnected when the coil is energized.
You can test the relay by conencting a 9V battery to pins #85 and #86. You should ear the relay ticking (it's the "needle" moving).
Then connect a ohm-meter on pins #30 and #87, it should read 0 ohms (circuit closed, passing) with the coil energized, and infinite resistance (circuit open) without coil energized.
#30 and #87A should be the contrary ;)
And because videos are easier to understand:
