Pin 87 - when the relay is 'on': Pin 30 and Pin 87 are connected
Pin 87a - when the relay is 'off': Pin 30 and Pin 87a are connected

About the Wire harness
Five 14AWG wires, rated for 20A:
#Black (85) - to Ground
#White (86) - to Switch or Trigger
#Blue (30)- to Battery Positive
#Red (87a)- Normally Closed Contact
#Yellow (87) - Normally Open Contact

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. Also, you can use 6.3 mm female connectors
to connect directly to the relay pins. The relay should be good for 30 amps.
