Radio installation, 1988 (US) 287
Operation
The facia is fitted with a radio contact box.
Three variants exist:
900 18: A radio contact box without amplifier
(348)
900116: A radio contact box with amplifier (349)
900716: A radio contact box with amplifier (348).
This contact box is equipped with a
shielded cable with an 18-pole connec-
tor, for the connection of a CD player or
equalizer. The shielded cable is fitted
with two 13-pole connectors 351 (DIN
connectors). The CD player or equalizer
can be connected by inserting it into a
contact box located in the top compart-
ment of the centre console.
In addition, the car is pre-wired, and speakers andan
electrically operated aerial are fitted, to facilitate the
installation of a radio.
The radio contact box must be connected to the aerial
cable and to two 10-pole connectors 98 (267), one
for the power supply and the other for the speakers.
The contact box with amplifier (349) is fitted with a
3A fuse and a 16A fuse.
3A 15A
Blade fuses for amplifier
Power supply
The following cables are connected to the upper
10-pole connector 98 shown on the wiring diagram:
Grey (pin 1) — Positive supply via fuse 28, which is
supplied directly from the battery (regardless of the
position of the ignition switch).
Red (pin 4) — Positive supply via the ignition switch
and fuse 20. The radio is supplied when the ignition
switch is in the parked or drive positions.
Black (pins 5, 9 and 10) — Earth.
Green (pin 6) — For control of the electrically oper-
ated aerial (265). The motor of the electrically oper-
ated aerial is supplied via fuse 28.
Brown/white (pin 8) — Dial lighting. The supply is
taken from the instrument lighting rheostat 17.
Speakers
The speaker connections are made via the lower
10-pole connector shown in the diagram.
Left-hand front:
Green (pin 1) —
Brown (pin 2) +
Right-hand front:
Red (pin 3) +
Blue (pin 4) —
Left-hand rear:
Green/white (pin 5) —
Brown/white (pin 6) +
Right-hand rear:
Red/white (pin 7) +
Blue/white (pin 8) —
Each speaker is connected via single-pole connector
60.
Fault-tracing hints
1. Check the supply to the radio and the earth
connection.
2. Check the connectors.
3. Check the existing cable harness for open cir-
Cuits and short circuits to earth.

Burglaralarm 291
Operation
Cars delivered to certain markets, including the
U.S.A. market, have provision for the installation of a
burglar alarm. A special cable harness and an 8-pole
connector (289) for connecting the burglar alarm
control unit are included.
The control unit is supplied from pin 1 of connector
289 (+30), regardless of the position of the ignition
switch, and from pin 5 (+X) when the ignition switch
is in the parked, drive or start position.
To prevent the burglar alarm from being set off, the
ignition key must be turned within a certain time after
a car door has been opened.
The movement detector can be switched on and off by
means of an ON/OFF switch connected to pin 7 of the
control unit (earth/no earth).
If the burglar alarm is activated, the alarm will be set
off if one of the following contacts should close:
© Door switches 54 connected to pin 8.
© Luggage compartment light switch 56, luggage
compartment lighting 55 or the HOOD switch,
which are connected to pin 6.
When the alarm is set off, the horn will be supplied
via pin 4, and the parking lights via pin 3.
The parking lights are supplied via pin 20 of 29-pole
white connector 152A, and include:
as Parking lights (front)
14 Rear lights
15 Number plate illumination
234 Side marker lights (certain markets)
Note: The wiring varies from one market to another,
and between the 3-D/5-D and 2-D/4-D models (see
the section entitled "Parking lights”).
Fault-tracing hints
1. Check that the supply to connector 289 (termi-
nals 1 and 5) is live.
2. Check the burglar alarm ON/OFF switch.
3. Check the door switches, luggage compartment
light switch and hood switch, and the corre-
sponding connections to connector 289.
4. Check the connectors, cable harnesses and
earth connections.
For fault-tracing hints on the parking lights, see the
section entitled ’Parking lights”.

Burglar alarm, Convertible
Operation
The car is equipped with a burglar alarm comprising a
control unit, movement detector, siren and transmit-
ters (switches) in the hood (bonnet), doors and lug-
gage compartment lid. For particulars of the oper-
ation of the control unit, i.e. the activation times for
the alarm, the time during which the siren will sound
when the alarm is set off, etc. see a separate in-
struction manual for the burglar alarm.
Control unit 289 and the associated cable harnesses
are connected to the wiring of the car via 8-pole
connector 122.
The control unit is supplied (+30) from pin 1 and
connector 122, regardless of the position of the igni-
tion switch, and from pin 5 (+X) when the ignition
switch is in the parked, drive or start position.
If the burglar alarm is activated (LED 305 is flashing),
the alarm will be set off if the movement detector 304
is activated or if one of the following contacts should
close:
@ Door switches 54 connected to pin 8. (Time-delay
relay 151 for the interior lighting affects only the
alarm activation time, approx. 15 seconds.)
@ Luggage compartment light switch 56 or hood
(bonnet) switch 276, which are connected to pin
6.
When the alarm is set off, siren 275 will be energised
from pin 4 and will sound. If the flasher relay is
connected to black connector 123C, the parking
lights of the car will also flash.
The parking lights are supplied via pin 20 of 29-pole
white connector 152A, and include:
13 Parking lights (front)
14 Rear lights
15 Number plate illumination
234 Side marker lights
If the headlamps (11/12) or extra fog lamps (85) are
switched on, they will also flash.
The movement detector can be switched off by
means of ON/OFF switch 288 connected to pin 7
(contacts closed).
if one of the seat switches 314 or 315 is closed at the
same time as the ignition switch is in the parked,
drive or start position, LED 305 will be switched off.
A receiver for remotely controlled de-activation can
be connected to white connector 57A. A transmitter
designed to intiate an alarm in a portable receiver
can be connected to red connector 57B. The blue
connector is not used at the present time.
Fault-tracing hints
Start by checking that the supply to connector 122
(terminals 1 and 5) is live with the ignition switch in
the appropriate position. Then follow the fault-trac-
ing instructions in the accompanying installation in-
structions.
For fault-tracing hints on the parking lights, see the
section entitled "Parking lights”.
