The automotive relay is an electronic control device, usually used in an automatic control circuit.
It is in fact an "automatic switch" that controls a large current through a small current.
It has the function of automatic adjustment, safety protection, and conversion circuit.

Wide Application:
Suits for all automobiles and devices equipped with a 12 Volt DC power source.
Used in led work light, fog lamps, starter, wiper, fans, speakers, central locking, alarm, electric windows, etc.

Instruction of Relays and Harness Sockets:
-85: Connected to the ground chassis. Serves as the common ground connection to activate and magnetize the internal coil.
-86: Connected to a positive 12V DC input. This is where a switch connected to 12V DC input will be connected to on the relay.
When power is sent to the relay through pin 86, the circuit is completed with pin 85 connected to a common ground, which activates and magnetizes the internal coil.
-87: Normally open contact, also known as NO.The connection between pin 87 and pin 30 is only made when the internal coil is activated or magnetized.
-30: Common contact which can be connected to a 12V DC power input or to the ground chassis depending on the desired application.

-87a: High Power Output-Normally Closed Contact.

Description

Package Content

• Power Relay (40A)
• Blade Fuse (30A)
• 2 sets of power connectors to light fixtures
• Illuminated Rocker Switch On/Off Rocker LED
• User Manual

Wiring Instructions:

1. Choose your desired mounting location for the switch. Mark and drill one 3/4" hole.
2. Use a sheet metal screw to mount the relay around the battery. Make sure the RED wire from the relay can be connected to the positive terminal of the battery while the BLACK wire can be grounded to the chassis.
3. Connect the WHITE wires to the positive input line of the auxiliary lights.
4. Connect the BLACK wires to the ground connection line of the auxiliary lights.
5. Connect and install the WHITE wire from the relay to the middle pin of the switch (COPPER colored).
6. Link the RED wire to the outer pin (COPPER colored) of the switch then route and connect it to a steady power source. Please make sure to use an in-line fuse rated at a minimum of 3A 12V DC when connecting this power feed wire directly to the battery. As your other option, you can also install this wire into an existing power wire in the cabin or into the cabin fuse box and this will exclude the need of an inline fuse.
7. Attach the BLACK wire to the pin of the switch (GOLD colored), route it then connect it to the ground chassis.
8. Finally, push the switch into the 3/4" hole that you drilled out (Step 1)
