Learn about Chevrolet Corvette (C8) 2020-2024 fuse box and relay’s locations, functions, and maintenance tips for optimal vehicle electrical system.
The Chevrolet Corvette C8 (2020-2024) marks a revolutionary shift in the Corvette lineup with its mid-engine sports car design, offering unmatched handling and performance. Available in coupe and convertible body styles, the C8’s bold, aerodynamic design reflects its high-performance capabilities. The interior is driver-focused, with premium materials, advanced technology, and customizable options that make it suitable for both track and street driving.
The Corvette C8’s electrical system is sophisticated, powering high-end features like the digital cockpit, infotainment system, and driving dynamics controls. The main fuse box is located in the front trunk (or “frunk”), while an additional fuse box can be found in the rear trunk area. Relays situated near these fuse boxes control essential functions such as ignition and cooling systems. Routine maintenance of these components is essential for optimal performance and functionality.

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.
