I spent hours looking over the electrical diagram from my build manual.
What helped me was to photocopy/enlarge it up to A3.
C I then went over the circuits with felt
pens in the correct colour, this made it much easier to trace the circuits.
Black/White and White/Black are NOT the same.
Read them as Black on White & White on black, with the underlying colour being
prominent and the overlying colour being thinner.
