：
Yellow
：
constant

of
12V
。
black
：
GND
of

RED[ACC]
：
when
the
monitor
works,
this
wire=12V
，
otherwise=0V
。
Green
：
reverse
signal
wire[=12V
when
in
reverse],
it
can
be
used:
To
give
reverse
signal
to
interface
box
，
also
giving
power
to
camera[max.1A]
When
giving
power
to
camera,
a
100u
capacitor
is
necessary
on
this
wire
to
filter
the

When
only
give

and
camera
is
powered
elsewhere,
do
not
add
