Wire Color Abbreviations
The following abbreviations are used to
identify wire colors in the circuit schematics:
BLK.... .........b|ack
BLU.... ......... blue
BRN.... ,....... brown
GRN.... ........ green
GRY.... ......,.. gray
LTBLU . .....lightbtue
LTGRN. ....lightgreen
ORN.... ....... orange
PNK .... .......,.. pink
PUR .... ........ purple
RED .... .......... red
WHT... .........white
YEL .... ........ yellow
A broken line means this part of the circuit
is not shown; refer to the circuit listed for
the complete schematic.

Wires
A wavy line at the end of
a wire means lhe wire is
broken by the binding of
the book or by a "choice"
bracket but continues on
the next page.
Wire insulation can be
one color, or one color
with another color stripe.
(The second color is
the stripe.)
This circuit continues on
another page. (The arrow
shows direction o{ current
flow.) To tollow the RED/
BLK wire in this example,
you would turn to page 23-5
and look for the "2" anow.
This means the branch of the
wire connects to another
circuit. The arrow Doints to the
name of the circuit branch
where the wire continues.
8LK-Cruise Control, €aaaGauges, Indrcalors

Wire choices for options or
different models are labeled
and shown with a "choice"
bracket like this.
This broken line means
both terminals are in
connector C134.
