There are a number of independently created wiring diagrams for the Chimaera available from a range of sources.
One of the clearest sets I have found are created and maintained by Steve Dunford, these are updated by Steve based on real owners feedback, meaning that they probably represent the most accurate set of wiring diagrams available.
If you want to get a copy of the latest Chimaera (also covers the Griffith) wiring diagram then please email Steve on steve_dunford1949@hotmail.com and he will assist.
Steve can also supply details of the inner workings of the Chimaera / Griffith fuse box.
Part complete diagrams are also available for the TVR S, V8S & Wedge.
