[A] : System Title [F] : Junction Block (The number in the circle is the J/B No.
and the connector code is shown beside it).
[B] : Indicates the wiring color.
Junction Blocks are shaded to clearly separate them
Wire colors are indicated by an alphabetical code. from other parts.
B = Black W = White BR = Brown
L = Blue V = Violet SB = Sky Blue Example:
R = Red G = Green LG = Light Green
3C indicates that
P = Pink Y = Yellow GR = Gray it is inside
Junction Block
O = Orange No.3
The first letter indicates the basic wire color and the
second letter indicates the color of the stripe.
