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.

Ttl
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.
