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.

Follow these steps to connect the
