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 match 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.

• If both a changer and an external amplifier are to be connected, connect the changer’s blue lead,

not the blue/white lead, to the amplifier’s trigger switch.

The changer harness also has gray, blue/white, and orange leads that are 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 amplifier’s trigger input terminal and/or antenna

motor trigger input terminal (if you have either or both of these items). The combined total

amperage required for triggering the antenna motor and/or amplifier must not exceed 300 mA.

DO NOT connect the blue lead to the antenna’s and/or amplifier’s power supply input.

4. Connect the black (power ground) lead to a grounded metal part on the vehicle. We

recommend grounding all audio system black ground leads (head unit, external amplifier, etc.)

to a common grounding point, preferably a non-painted surface under the instrument panel.

5. 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.

6. 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.

7. 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 radio or vehicle.

8. Reconnect the vehicle’s battery.

9. Verify that no fuses have blown.

10. Plug the harness into the unit.

11. Attach the faceplate and test the unit.

Once the connections have been successfully made, you can begin to mount the unit.

SPEAKER CONNECTIONS

he 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 tremendous

flexibility in configuring your speaker arrangement:

• You can connect a speaker (regular, co-axial or tri-axial speakers or component speaker system,

all hereafter referred to simply as “speaker”) to each of the units’ four pairs of speaker leads.
