simply turns it on or off. If you do not use this wire, use a wire tie
to keep it out of the way.
If your vehicle has an automatic antenna, connect the AMP REMOTE TURN ON
lead to the vehicle's power Antenna lead.
Note: The optional component must be designed for use with an amp remote
turn on lead for the above connection. See the optional component's
owner manual.
CONNECTING TO YOUR CAR PHONE
If you want the stereo's sound to mute when you use your car phone,
connect the pink/white wire to your car phone's mute terminal.
CONNECTING TO POWER AND YOUR VEHICLE'S ANTENNA
1. Connect the stereo's black ground wire to a metal screw attached to
the vehicle's frame. Be sure the screw is not insulated from the
chassis by a plastic part.
2. Connect the stereo's yellow wire (with an in-line fuse holder and
MEMORY BACKUP LEAD label) to your battery's positive (+) terminal or
to a non-switched fuse terminal (a terminal that the vehicle's
ignition does not turn on and off). This connection provides 12
volts of continuous power for the radio's memory and the security LED
when the ignition is turned off.
3. Connect the wire labeled POWER LEAD B (+) (with an in-line fuse
holder) to the accessory (ACC) terminal on your vehicle's fuse block.
This connection provides power to the stereo when you turn on the
ignition, and turns off power when you turn off the ignition. This
prevents your vehicle's battery from draining if you leave the stereo
on and turn off the ignition.
4. Connect the vehicle's antenna cable to the stereo's large antenna
connector.
When all connections are complete, reconnect the battery cable.
