The wiring schematics included in the parts books introduced across the Classic and M3W range from around 2006 onwards are difficult to read initially, having a degree of OCD helps though . Given the huge increase in electrical and electronic complexity they are probably one of the few practical solutions by effectively compacting the detail into the display of the physical looms that carry all the cables and their connectors, whilst adding loom dimensions not available in the old format. Each cable run is uniquely identified at each end with colour code and number. Multiple connection/distribution points (bombtails) with cable identifiers are also shown with location on loom.

The introduction for the 3.7 Roadster of 25 or so additional old style wiring diagrams covering in isolation engine and body aspects from battery to devices, was a big step forward and greatly eased cable tracing and specific fault finding. Sadly it seems never to be repeated for other models.

I would add I've found relatively few errors in the schematics which also include fuse box layout and wire codes. I admit to finding cable ends that appear to vanish but without exception find the other coded end eventually . I simply don't see the need therefore to reverse engineer a full wiring loom when it's effectively been done and for each variant.
