The Vectra C made its official debut at the Geneva Motor Show in 2002. Built on the GM Epsilon platform, it was initially available as a four-door sedan and a five-door hatchback (known as the GTS). A five-door station wagon was added in October 2003. This article provides detailed fuse box diagrams and relay assignments for the Opel / Vauxhall Vectra C (third generation; Epsilon platform) produced for model years 2002 through 2010.
Below you will find fuse box locations, component layouts, and photos. Fuses protecting the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
Engine Compartment
Two fuse boxes are located in the engine compartment to protect the primary vehicle circuits.
