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.

memory backup power, and optional

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.
