Letters: These represent specific components.

Fuses and Relays

Fuses and relays are essential components of any electrical system. The fuse block provides protection against over-currents and is connected to the main power source. Fuses and relays are interchangeable, but each one is designed to provide protection to certain systems in your car. For instance, a relay may be used to protect the fuel pump while a fuse may be used to protect the starter motor.

Ground Terminal

The ground terminal is another important component of a fuse box. This terminal connects to a metal strip or grounding cable. This connection completes the circuit and helps protect the vehicle’s electrical system by ensuring that any excess current is safely diverted away from sensitive components.
