Using an Adapter Harness
If you are replacing an existing
stereo, or if your vehicle has been
factory-wired for autosound compo-
nents, you might be able to use an
adapter harness to connect the pow-
er and speakers. RadioShack stores
sell adapter harnesses for most ve-
hicles.
Follow the directions that come with
the adapter harness to temporarily
connect the ground, power, optional
components, and speakers. Then go
to “Connecting the Antenna” on
Page 9.
Connecting Ground, Power,
and Optional Components
Follow these steps to connect the
supplied harness 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 ter-
minal.

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 LEAD
(B+) wire (with in-line filter and
fuse holder) to a point in your
vehicle’s fuse block that has
power only when you turn the
vehicle’s key to either the acces-
sory (ACC) or START position.
This connection turns on the ste-
reo when you turn on the ignition
or turn the key to ACC, and
turns off the stereo when you
turn off the ignition. This pre-
vents your vehicle’s battery from
being drained if you leave the
stereo on when you turn off the
ignition.
4. Connect the yellow CLOCK
MEMORY wire (with in-line fuse
holder) to your vehicle battery’s
positive (+) terminal or to a point
in your vehicle’s fuse block that
provides a continuous source of
12 volts.
This connection provides contin-
uous power for the stereo’s
