• The stereo’s buzzer alarm sounds if
you make an incorrect connection.
For example, speaker wires make
contact to ground and the battery’s
positive (+) terminal for around 5
seconds with the power leads con-
nected to the battery’s positive ter-
minal and the ground wire
connected to the battery’s negative
terminal.
Using an Adapter Harness
If you are replacing an existing stereo,
or if your vehicle has been factory-wired
for autosound components, you might
be able to use an adapter harness to
connect the power and speakers. Ra-
dioShack stores sell adapter harnesses
for most vehicles.
Follow the directions that come with the
adapter harness to temporarily connect
the ground, power optional components,
and speakers. Then go to “Completing
the Connections” on Page 9.
Connecting Ground, Power,
and Optional Components
Follow these steps to connect the har-
ness with the 14-pin connector to
ground, primary and memory backup
power, and optional components.
1. Disconnect the cable from your
vehicle's negative (–) battery termi-
nal.
2. Connect the black ground wire to a
chassis ground, such as a metal
screw attached to a metal part of the
vehicle's frame. Be sure that the
screw is not insulated from the
chassis by a plastic part.
3. Connect the red power wire (with fil-
ter and fuse box) to a point in your
vehicle's fuse block that has power
only when you turn the vehicle's key
to either the accessory (ACC) or ON
position. This connection turns on
the stereo when you turn on the igni-
tion or turn the key to ACC, and
turns off the stereo when you turn
off the ignition. This prevents your
vehicle's battery from being drained
if you leave the stereo on when you
turn off the ignition.
4. Connect the yellow power/memory
wire (with filter and fuse box) to your
vehicle battery's positive (+) termi-
nal or to a point in your vehicle's
fuse block that provides a continu-
ous source of 12 volts.
This connection provides power for
the stereo's components, and con-
tinuous power for the stereo's mem-
ory when the ignition is turned off.
