Installation
• You must connect the ground and
primary wires first, then make all
other connections before you plug
the 14-wire harness into the stereo.
(See “Using an Adapter Harness.”)
If you do not make connections in
the order shown, damage to the ste-
reo is possible if any wire connec-
tions are made incorrectly.
• You must connect a separate wire to
each speaker terminal as described
in the following procedure. Do not
use a common wire or chassis
ground for any speaker connection.
Using an Adapter Harness
If you are replacing an existing stereo,
or if your vehicle has been factory-wired
for auto-sound components, you might
be able to use an adapter harness to
connect the power and speakers.
Follow the directions supplied with the
adapter harness to temporarily connect
the power and speakers.
A selection of adapter harnesses is
available at your local RadioShack
store.
Connecting Ground, Power, and Optional Components
Follow these steps to connect the sup-
plied harness with the 14-pin connector
to ground, power, and optional compo-
nents.
1. Disconnect the cable from your
vehicle battery's negative (–) 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
+12V TO IGNITION
wire (with the in-line fuse holder) to
a point in your vehicle's fuse block
that has power only when you turn
the vehicle's ignition key to either
the accessory (ACC) or ON position.
