What role do Relay Boxes play in the operation of electrical accessories on 2017 Volkswagen Jetta?

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 faulty relay can cause improper component operation, and most relays are found in the engine compartment fuse/relay box.
