(120-2180)

Before you mount the CD changer and its components, test it by temporarily connecting all components, connecting the power wires, and connecting the FM modulator to your vehicle and your sound system.

CAUTIONS: For added safety and to protect the CD changer and sound system, disconnect the cable from your vehicle battery's negative (-) terminal before you begin.

You must make all other connections (as described in the following sections) before you reconnect the cable to your vehicle's battery. If you do not make the connections in the order shown, damage to the CD changer and sound system is possible if any wire connections are made incorrectly.

CONNECTING THE FM MODULATOR

The FM modulator includes all of the lead wires for connecting to your vehicle's ground, power, and sound system.

1.Disconnect the cable from your vehicle battery's negative (-) 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 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 CD changer and its components when you turn on the ignition or turn the key to ACC, and turns off the CD changer and its components when you turn off the ignition. This prevents your vehicle's battery from being drained if you leave the CD changer on when you turn off the ignition.

4.Connect the yellow memory back up wire (with in-line fuse holder) to your vehicle battery's position (+) terminal or to a fuse that provides a continuous source of 12 volts.

This connection provides power for the CD changer and its components, and continuous power for the CD changer's memory when the ignition is turned off.
