2 Switch 1 bulb wiring connection

Main Parts
• Coil: A wire-wound core that creates a magnetic field when powered.
• Armature: A spring-loaded metal piece that moves when the magnetic field forms.
• Contacts: Switch points that open or close the high-current circuit.
Terminal Numbers and Functions
• Terminal 30: Common power input from the battery.
• Terminal 85: Coil ground connection (-).
• Terminal 86: Coil power or trigger signal (+).
• Terminal 87: Normally Open (NO) output to the load.
• Terminal 87a: Normally Closed (NC) output (on 5-pin relays).
If you'd like, let me know:
• What component you are trying to wire (e.g., lights, horn, fuel pump)
• Whether your relay is 4-pin or 5-pin
I can give you a step-by-step wiring guide for your setup.
