Notes

1.

Wire identification is not by colour, but by
letters or numbers appearing on the wire
at each end.

2.

Wires may interconnect between diagrams
and are located by using a grid reference
e.g. 2/A1 denotes a position on diagram 2
grid location A1.

3.

Brackets show how circuits may be wired
in more than one way.

4.

Not all items are fitted to all models.
