Peugeot 406 Wiring Diagram May 2026

Overall Rating: ⭐⭐⭐☆☆ (3/5) Best for: Dedicated DIY mechanics and auto electricians. Worst for: Beginners hoping for a simple color-coded chart.

Owning a Peugeot 406—whether the classic saloon, the practical SW estate, or the handsome coupé—is a exercise in appreciating French engineering. However, when an electrical gremlin strikes (and they will, from the infamous COM2000 indicator stalk to the blower motor resistor), the factory wiring diagram becomes less of a luxury and more of a survival tool.
