TIPM cartridge fuses (J1-J22)
On a 2012 Ram 1500 the fuses sit in the Totally Integrated Power Module beside the battery, driver's side of the engine compartment. The module numbers its cartridges J1 to J22 and its mini fuses M1 to M38 separately, so the cartridges are on this diagram and the mini fuses on the next.
The 2012 manual rearranges the cartridges: J15 becomes the 40 A front blower, the rear defroster moves to J12, J10 feeds the sway-bar disconnect and J11 the transfer case module. This is the last year of the TIPM before the 2013 refresh.

TIPM mini fuses (M1-M38)
The 2012 Ram 1500's mini fuses, M1 to M38, share the Totally Integrated Power Module with the cartridges; the box is in the engine bay beside the battery on the driver's side. Empty cartridge sockets on this drawing are the J series on the other diagram.
New in the 2012 list: M18 for the centre high-mounted stop lamp, M26 for the driver door switch instead of a spare, M31 for the back-up lamps, and M10 drops to 15 A. The airbag pair M32/M16 still sits under its yellow cover.
