Engine compartment fuse box (2UZ-FE V8)
Model year 2002 is documented by OM34417U (L/O 0108), whose V8 plate is the R80013 drawing carried over from 2001: the same box on the driver's side of the engine compartment beside the battery, with a clip-off lid that holds the puller and the spares. Nothing moved. The left column still runs four cartridges into seven blades, the right two cartridges into ten blades ordered 8, 9, 14, 15, 16, 10, 11, blank, 12, 13, and the alternator link sits above the middle. The single difference from the previous printing is AM2, rated 30 A in this edition where the 2001 book alone printed 40 A.

Engine compartment fuse box (5VZ-FE V6)
Plate R80014 is reprinted unchanged in the 2002 manual: the V6 box lives against the battery on the driver's side of the engine bay and its cover unclips upwards. The sockets for ETCS and EFI NO.2 stay hatched on this drawing, so twenty-one positions are fitted against the V8 plate's twenty-three, and the small relay at the bottom left is likewise absent. Numbers follow the 2001 sequence and continue into the cab box; the only rating the 2002 edition changes anywhere in the truck is the AM2 cartridge, printed here at 30 A.

Instrument panel fuse box
The 2002 owner's manual reprints plate R80016 for the cab: a block behind the removable trim at the driver's kick panel, just left of the steering column. Three columns of horizontal MINI blades hold 17 to 20, 21 to 25 and 26 to 29, each filled downwards, the first socket of the first column left empty, and the POWER cartridge, 36, is mounted above the right-hand column. The assignment matches 2001 exactly; only the engine box's AM2 rating separates the two editions.

Towing kit fuse holder (engine compartment)
Only trucks specified with the towing package have this holder, a single cartridge socket sitting next to the main engine compartment box on the driver's side. Lift its small hinged lid to reach FL, 30 A, which feeds the trailer lights. The 2002 book numbers it 37 on holder plate R80015, exactly as the 2001 book did.
