Electrical Connections and Installation

@/<?#&*>@! To avoid the aggravation of costly mistakes and serious damage that could make
you feel this way, please carefully read all of the instructions before you begin. Carefully follow all
instructions. You'll be glad you did!
GENERAL RECOMMENDATIONS
• If you're not confident that you can install the unit correctly, have it installed by a qualified
Blaupunkt installation technician.
• Use this unit only with negative ground 12 Volt (11-16 Volt) direct current (DC).
• Be sure to detach the faceplate before you start to connect or install the unit.
• Don't assume that a seemingly matching wire harness in the vehicle has leads that matehc the
leads of the unit's wire harness.
• We recommend making and testing all electrical connections before installing the unit. Connect
the leads (wires) according to instructions and diagram below.
IF YOU ARE INSTALLING A COMPATIBLE BLAUPUNKT CD CHANGER
• For speaker connection, use the speaker wire harness section that comes with the receiver.
• For other connections, use the wire harness sections that come with the CD Changer, not the
receiver.
• Note that some of the CD Changer's wire harness leads have different colors:
- In place of yellow lead, use red lead (that has yellow BATT. clip) for constant power.
- In place of black lead, use brown lead for ground.
- In place of dark green lead, use gray lead for cellular mute.
The changer harness also had an orange lead that is non-functional with this receiver.
ELECTRICAL CONNECTION INSTRUCTIONS
1. Disconnect the vehicle battery's negative terminal before making connections.
2. Connect the speakers and/or external amplifiers (if you have any) following the guidelines in
the SPEAKER CONNECTION section below.
3. Connect the blue (trigger output) lead to an antenna motor trigger switch input terminal (if you
have one). (Maximum amperage required must not exceed 150mA.)
4. If you have an external amplifier, connect the blue/white lead to the amplifier's trigger switch
terminal. DO NOT connect the blue/white lead to the antenna's power supply input. (Maximum
amperage required must not exceed 150mA.)
5. If you have a cellular telephone set that has a mute lead (lead that supplies constant ground
when telephone is in use), connect it to the dark green lead.
6. Connect the black (power ground) lead to a grounded metal part on the vehicle. We
recommend grounding all audio system black ground leads (receiver, external amplifier, etc.) to
a common grounding point, preferably a non-painted surface under the instrument panel.
7. Connect the yellow (constant power) input lead to a source of constant battery power,
preferably a terminal to an appropriate slot in the fuse box.
8. Connect the red (turn-on power) input lead only after the other leads are connected. Be sure to
connect the red lead to a positive (+) 12 Volt power terminal that is energized only when the
ignition key is set to the on position or accessory position.
9. Cover the ends of any unused leads with electrical tape. This will prevent them from touching
the vehicle or each other and causing a short-circuit and damage to the unit or vehicle.
10. Reconnect the vehicle's battery.
11. Verify that no fuses have blown.
12. Plug the harness into the unit.
13. Attach the faceplate and test the unit.
Once the connections have been successfully made, you can begin to mount the unit.
SPEAKER CONNECTIONS
The unit's Dual-Level Fader allows you to fade between the front and the rear channels using
either the front and/or rear speaker leads and/or the rear preamp outputs, providing you
