Find the Ford Bronco Sport 2021-2024 fuse box and relay locations with diagrams. Learn how to maintain the electrical system for reliable performance.
The Ford Bronco Sport (2021-2024) is a compact SUV built for adventure, featuring rugged styling and versatile body designs. With its boxy shape and off-road-ready aesthetics, it appeals to drivers who value functionality and style. The Bronco Sport is available in several trims, including Base, Big Bend, Outer Banks, and Badlands, offering options for urban driving or off-road exploration. Its spacious interior, fold-flat rear seats, and advanced technology features make it both practical and comfortable.
The Bronco Sport’s advanced electrical systems rely on its fuse box and relays to power critical components like lighting, climate control, and engine systems. The primary fuse box is located in the engine compartment, while another fuse box is positioned in the passenger cabin, under the dashboard. Relays, which control high-power components such as the fuel pump and starter, are housed near the fuse boxes. Routine inspection and replacement of fuses and relays ensure the Bronco Sport’s features perform reliably.

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.
