on a normal relay.. 85 or 86 can be ground or positive, doesn't matter really. But when the relay sees both positive and ground switched (ign or otherwise triggered input voltage) on those; whatever is connected through pin 30 [constantly] voltage or ground wise will switch through to pin 87 [out] from 87a.
The IGN controls the source of power through 30 or 87 whichever you choose.
So for like a turn on relay only function. I like to hold a relay so the odd pin (30) is at the bottom. In a clock wise fashion I start there as
30 [IN]
85 [HOT]
87 [OUT]
86 [GRND]
87a [/ not used]
