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 yellow clock memory wire (with in-line fuse holder) to
your vehicle's positive (+) battery 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 clock), and continuous power for the stereo's memory when the
ignition is off.
5. Connect the blue/white wire to any optional equipment (designed to run
from a switched source) that you want the stereo to turn on and off
(such as a remote amplifier or a power antenna).
This wire does not provide power to the components. It simply turns
them on or off. If you do not use this wire, secure it with a wire tie
and do not let it touch metal.
Note: To connect an optional amplifier (such as RadioShack Cat. No.
12-2018), use the line out connectors on the back of your car
stereo and follow the instructions in the amplifier's owner's
manual.

2. Connect the gray/black wire to the right front speaker's negative (-)
terminal. This terminal might be marked with a minus (-) sign or it
might not be marked at all.
3. Connect the white wire to the left front speaker's positive (+)
terminal.
