This page lists alternative and donor parts that Cerbera owners have used in place of original TVR-supplied items for the electrical system, interior fittings and bodywork. It applies to the TVR Cerbera and is compiled from Alex Judd’s community parts list. Always cross-check fitment and electrical polarity before ordering — Cerberas vary across the production run and some items need minor bracket or wiring tweaks.
The Cerbera fusebox carries a numbered set of relays. Where a position is “blank” on a given car it is left in the list for reference. Most are standard automotive 4- or 5-pin units.
