Engine compartment fuse box
Driver's side of the engine compartment, beside the battery: press the tab on the lid and lift it away. The pull-out tool inside handles the small blade fuses; Toyota lists the cartridges as dealer parts. The 2007 book, OM34463U ("from Jul. '07 prod."), numbers both of the truck's boxes in one run on plate XS73034 - blades 1 to 34 here, the fusible-link elements 60 to 65 (HTR, LH-J/B, ALT, A/PUMP, MAIN) and the cartridges 66 to 70 (DEFOG, SUB BATT, ABS1, ABS2, ST) also here, with 35 to 59 and 71 inside the cab. Four blades stand alone across the top, the three spares sit at the top right, and the link block fills the lower left corner.

Instrument panel fuse box
Down in the driver's footwell, looking up at the underside of the instrument panel: take the lid off and the fuses face you in two rows. The 2007 numbering does not restart for this carrier - plate XS73028 gives it 35 to 59 for the blades and 71 for the POWER No.1 cartridge, continuing the engine box's run. Both rows are read from the left, and the cartridge stands among the upper one. The blades here are full-size parts, unlike the MINI fuses under the hood.
