Connecting Ground, Power, and Optional Components

Follow these steps to connect the wiring harness to ground, power, clock memory,
and optional components.

Wires
1. Disconnect the cable from your
vehicle's negative (
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 the
screw is not insulated from the
chassis by a plastic or rubber part.
3. Connect the red +12V To Ignition wire
(with in-line fuse holder) to a point in
your vehicle's fuse block that has
power only when you turn the vehi-
cle'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 igni-
tion.
4. Connect the yellow +12V To Battery
wire (with in-line fuse holder) to your

vehicle's positive (+) battery termi-
nal or to a point in your vehicle's
fuse block that provides a continu-
ous source of 12 volts. This connec-
tion provides power for the stereo's
components (such as the clock),
and continuous power for the ste-
reo'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.
