1. Under the hood: This is the main fuse/relay center, often located near the battery. This box contains the highest amperage fuses and many relays.
2. Inside the car: This is usually found under the dashboard, often on the driver's side. This box contains lower amperage fuses for interior components. Sometimes this is referred to as an "interior fuse panel" and might be considered a separate "box" by some, but it's all part of the car's electrical system.
There isn't a third distinct fuse box. Any other relays or fuses might be located inline with specific circuits and not grouped in a centralized location. Your owner's manual will be the best resource for their specific locations and the purpose of each fuse and relay.
