Engine compartment fuse box
A third insertion in three years: the air-injection pump heater fuse - AI PMP HTR on V6 trucks, AI-HTR on V8s, 10 A - takes position 15 in the 2011 book, shifting everything after it and bringing the engine box to 1 to 47. Access is as before, on the driver's side of the compartment beside the battery, pushing the lid tab and lifting. On the plate: four blades stand alone across the top with the spares to their right, the middle and right groups hold most of the blades, ABS1, ABS2 and ST are the cartridges beside the middle group, and HTR, LH-J/B, ALT, two A/PUMP elements and MAIN form the block in the lower left.

Instrument panel fuse box
From the 2011 edition the CIG socket is no longer assigned, so this carrier counts twenty-seven positions and the POWER No.1 cartridge ends the sequence at 27. Find it under the driver's side of the instrument panel; the lid pulls off downwards and the two rows of full-size blades face into the footwell, both read from the left.
