The Peugeot 408 debuted in early 2010 at the Beijing Motor Show. Despite its model designation, it is not the successor to the 407, but rather a sedan derivative of the 308 hatchback. Designed as a global model, it was developed primarily for the Russian, Chinese, and Latin American markets. This article provides comprehensive fuse box diagrams and terminal assignments for the first-generation Peugeot 408 (chassis code T7; PSA PF2 platform; model years 2012–2017).
Below are the locations, diagrams, and photographic guides for all power distribution blocks. Fuses for key circuits, such as the “Cigarette Lighter” and “Fuel Pump,” are bolded for quick identification.
Passenger Compartment Fuse Box
The fuse box is located under the instrument panel on the driver’s side.
