connections in the order shown, damage to the stereo is
possible if any wire connections 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. 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" below.
Connecting Ground, Power, and Optional Components
Follow these steps to connect the 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
terminal.
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 power wire (with in-line 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 accessory (ACC) or START position
This connection turns on the stereo when you turn on the ignition or
turn the key to ACC, and turns off the stereo when you turn off the
ignition. This prevents your vehicle's battery from being drained if
you leave the stereo on when you turn off the ignition.
4. Connect the 12V TO BATTERY 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 power for the stereo's components (such as
the stereo), and continuous power for the stereo's memory when the
ignition is turned off.
5. Connect the blue/white AMP REMOTE TURN ON 500 mA MAX wire to any
