Ford Mustang S197 2010-2014 is the facelifted portion of the fifth generation. Its fuse assignments differ from the 2005-2009 S197, and Shelby versions add circuits for a second fuel pump, intercooler pump, injectors and differential oil pump.
For the earlier S197, see Ford Mustang 2005-2009.

FAQ – Ford Mustang 2010-2014 fuses
Does a Shelby use the same fuse table?
The main box is shared, but Shelby-specific rows must be followed for the second fuel pump, intercooler pump, injectors and differential oil pump.
Where is the OBD-II fuse?
Passenger-compartment position 20 – 15 A.
