*Indicates shielded wire.
*Shielded wire:
Prevents signal disturbances due to
electrical interference.
Wire is covered by a metal meshing for
grounding.
*Two-color wires are indicated by a Two-letter
symbol. The first letter indicates the base color of
the wire and the second indicates the color of the
stripe.
For example
W/R is a white wire with a red strip
BR/Y is a brown wire with a yellow strip
