The accessory fuse box is located directly under the dash on the drivers side. There are two black clips which must be pressed in to allow you to "swing" the fuse box down. At present, it currently sits upside down, facing to the floor. It's parallel to the drivers side A/C vent but behind it.
The MAIN fuse box (which has the LARGE fuses) is located on that wiring block on the passenger side directly behind the battery.
Hope that helps.
