Ulincos Auto Relay U1914 with 14AWG Wire Harness, 12V DC 30/40A SPDT 5-Pin (Pack of 2)

SPDT Relay - Single Pole Double Throw, you can use them to open or close a circuit -- or go from bright to dim on your headlights.

30/40A Relay - It is rated to handle 40 amps of load at 12V DC in the Normally Open position (PIN 87), and 30 amps of load at 12V DC in the Normally Closed position (PIN 87a). You can use it in any circuit less than 30A.

With the Wire Harness - Makes relay installation a breeze. If one goes bad, just unplug it from the socket and plug in a new one.

Each socket has a male and female slide. You can connect as many of these together next to each other as possible. This makes mounting them easy and clean looking.

Wide range of use, can be used in automotive setup, seat warming, vehicle lighting system, car sound system and various other applications.

About the Relay
Relay is an electrical control device that usually used in automatic control circuit.
The relay in fact is an automatic switch which uses a smaller current to control a larger current.

What's the Relay Used for
Compatible with almost all automobiles and devices equipped with a 12V DC power supply.
Like starter kills, power door lock/actuator control, change a low current output to high current, add ignition/accessory outputs,
control motors/other electronics. It is also suitable for automobile used for control, alarms, horn, headlight and more.

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 85 - is usually negative (-)
- Pin 86 - is usually positive (+)
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
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.
