The Chevrolet Corvette C7 (2014-2019) is known for its high-performance capabilities and advanced technology super car. Like any modern vehicle, the C7’s electrical system relies on a network of fuses and relays to ensure safety and functionality.
The fuse box in the C7 is located in two key areas: the engine compartment and the passenger compartment. The engine compartment fuse box handles essential high-power systems like the engine control module, cooling fans, and exterior lighting. The passenger compartment fuse box protects lower-power systems such as the infotainment system, interior lighting, and power windows. These fuses protect the electrical circuits by breaking the flow of electricity in case of an overload or short circuit.
Relays in the Corvette C7 act as switches to manage high-current components such as the fuel pump, starter motor, and cooling fans. These relays allow the vehicle to safely control these high-power systems using low-power signals. Regular inspection and maintenance of the fuses and relays are essential for preventing electrical issues and ensuring all systems in the Corvette C7, from performance to comfort features, function properly.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
