The Vectra B was unveiled in October 1995 at the Frankfurt Motor Show. A year later, in September 1996, the Caravan (station wagon) version was introduced. It was exported to Brazil under the Chevrolet brand, and in Australia and New Zealand it was sold as the Holden Vectra. This guide provides detailed fuse box diagrams and relay assignments for the second-generation Opel / Vauxhall Vectra B (GM2900 platform; model years 1995–2003).
Below you will find the locations, schematics, and photographs for the power distribution boxes. Fuses for critical components, such as the “Cigarette lighter” and “Fuel Pump,” are highlighted in bold.
