The S3 Wiring diagram at the back of Steve Heath's 'Bible' is quite difficult to read.

Other automobile wiring diagrams I've seen have been somewhat modularised in terms of picking out electrical sections,

for example interior lighting, horns etc.

With that in mind I've redrawn some of the circuits individually.
