About the Relay Pins
Pins 85 & 86 - are used to turn 'on' the relay. You need a positive (+) and negative (-) power source to
turn on the relay.

Pin 30 - is either a (+) or (-) source that feeds Pin 87 or Pin 87a
Pin 87 - when the relay is 'on': Pin 30 and Pin 87 are connected
What's Note
* The relay is rated for 30A, while the socket 14AWG wires are not big enough for the rated 30/40 amps.
If you are intending to run 30 amps continuously, you could remove the spade contacts from the connector,
carefully open the crimps securing the wire to the contact and recrimp/solder 10 gauge wires to it.
