2. Connect the BLACK wire to chassis ground. Prepare the chassis ground by scraping any
paint from the metal surface and thoroughly clean the area of all dirt and grease. Strip the
end of the wire and attach a ring connector. Fasten the wire to the chassis using a non-
anodized screw and star washer.
3. Connect the
YELLOW wire to a source of constant +12V (for retaining memory on user-
programmed functions). The source should always have +12V, even when the ignition is off
and the car is not running.
4. Connect the
RED wire (Ignition) to a source of switched +12V (is on only when ignition
key is in “accessory” or “run” position). Connect the RED wire to a switched +12 volt posi-
tive source. The switched signal is usually taken from the ACC (accessory) position of the
ignition. If the vehicle does not have an ACC position, connect the wire to the switched
ON position of the ignition. The current consumption through this wire is negligible.
5. Connect the
LT. BLUE wire to the “Remote Turn-On” leads of the amplifier(s). This will
turn-on the external amplifiers when the source unit is powered on.
6. Connect the BLUE/RED wire to the “Power Antenna” lead. This will raise a fully automatic
antenna when the source unit is powered on, but only when the unit is in Tuner Mode.
7. Connect the Speaker Wires (if external amplifiers are not used) to the corresponding speak-
er leads by soldering and heat shrinking all connections for a reliable installation. If only
one pair of speakers is utilized in the system, use only the
FRONT speaker leads and heat
shrink the unused REAR leads to prevent from shorting out. Be sure to maintain speaker
polarity. DO NOT chassis ground any speaker leads as unstable operation may result.
8. Install the Preamp Output Harness (if external amplifiers will be used) by plugging the RCA
cables into the corresponding extension RCAs that feed the input of the amplifiers. Be sure
to route the signal cables away from any high current wires to prevent coupling noise from
radiated electrical fields into the audio signal. The
FRONT RCAs connect to the Front
speaker's amplifier. The REAR RCAs connect to the Rear speaker's amplifier.
9. Connect the Antenna by plugging the antenna cable into the connector located at the rear
of the source unit. Be sure the antenna is securely grounded to the vehicle for proper radio
reception.
