Note: The wires in the wiring harness
have the following colors and labels.
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 har-
ness to connect the power and speak-
ers. RadioShack 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 “Connecting the Antenna” on
Page 11.
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 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.
