What role do Relay Boxes play in the operation of electrical accessories on 2006 Mazda 6?

Electrical accessories in vehicles, like the fuel injection system and horns, use relays to transmit signals. Relays operate a low-current control circuit to manage a high-current power circuit. A defective relay can prevent proper operation of the component. Most relays are found in the engine compartment and fuse boxes.
