Speed control module
Models before April 1992
9Refer to Section 27. The speed control
module shares the same mountings as the
AWS module; the AWS module is larger.
Models from April 1992
10The speed control module fitted to these
models is situated behind the glovebox on the
left-hand side of the facia. To gain access to
the module remove the left-hand facia
undercover panel. The speed control module
is vertically mounted just to the right of the
engine management module. Push the module
upwards to release the retaining clips then
lower it out from under the facia and
disconnect the wiring connector (see
illustration).
11Refitting is a reverse of the removal
procedure ensuring that the module is
securely retained by the retaining clips.
Vacuum pump
12The vacuum pump is located behind the
left-hand headlight on carburettor models, and
behind the right-hand headlight on fue-
injection models. Start by removing the
appropriate headlight unit.
13Disconnect the multi-plug and the vacuum
hose from the pump. The multi-plug is
released by squeezing and pulling it at the
same time.
14Prise out the three mountings and remove
the pump.
15When refitting, pull the pump mountings
into position with pliers. 16Reconnect the vacuum hose and the
multi-plug, then refit the headlight unit.
Vacuum servo
17Disconnect the servo-to-throttle linkage
cable at one end.
18Disconnect the vacuum hose from the
servo.
19Undo the servo retaining nut and remove
the servo from its bracket.
20Refit by reversing the removal operations.
On all but 2.0 litre carburettor models, adjust
the cable so that it is slightly slack when the
throttle linkage is in the idle position (pedal
released).
21On 2.0 litre carburettor models, the
stepper motor plunger must be withdrawn
before the cable is adjusted. Proceed as
follows.
22Observe the stepper motor plunger. Have
an assistant switch on the ignition for a few
seconds, then switch it off again. When the
ignition is switched off, the stepper motor
plunger will retract fully (“vent manifold”
position). Disconnect the battery negative lead
while the stepper motor plunger is retracted.
23Adjust the servo cable so that it is slightly
slack, then reconnect the battery negative
lead.
Printed circuit board
24The printed circuit board is located in the
steering wheel. It can be removed after
detaching the horn contact plate and
disconnecting the switch spade terminals as
described at the beginning of this Section.1Disconnect the battery negative lead.
2Pull off the rubber sealing strip from the top
of the plenum chamber (see illustration).
3Pull the two wiring harness clips from the
front of the plenum chamber (see illustration).
4Remove the two screws and two clips
which secure the plenum chamber cover (see
illustration). Lift out the cover.
5Disconnect the multi-plug from the blower
motor resistor. Also disconnect the motor
earth cable (see illustration).
6Remove the two nuts which secure the
motor assembly. Lift out the motor, casing and
resistor together.
7The casing halves and the resistor can be
separated from the motor after prising open
the clamp which holds the casing halves
together.
8Refit by reversing the removal operations.
1Two DIN standard extraction tools will be
needed to remove the radio/cassette unit.
These tools are available from vehicle audio
equipment specialists.
Radio (only)
2Pull off the control knobs, remove the
spindle nuts and washers and remove the
radio face plate.
3Push the two securing lugs inwards, at the
same time pulling the radio from its location.
The services of an assistant may be required.
4Withdraw the radio and disconnect the
aerial cable and the other wiring plugs from it.
5If a new radio is to be fitted, transfer the
support brackets and locating plate from the
old unit to the new one.
6Refit by reconnecting the wiring to the radio,
then sliding it into its aperture. Press it in until
the securing lugs click into position.
7Refit the face plate, spindle nuts and washers
and control knobs. The top of the face plate is
marked on the side which faces the radio.

Explanatory notes for wiring diagrams
Each wiring diagram covers a particular system of the vehicle; as indicated in each caption. When a number is shown on a diagram inside a box
with an arrow symbol, this indicates that the circuit concerned starts, or is continued, in the diagram having that number.
Space limitations mean that not all diagrams have been included. Therefore the diagram numbers are not consecutive, neither is it always
possible to follow a particular circuit to completion. Some diagrams are out of sequence; this is to ensure that the halves of the larger diagrams
appear on opposite pages.
The prefix C indicates a connector or multi-plug, S a soldered joint and G an earthing point (ground). The numbers appearing at the break in
each wire indicate the circuit number and wire colour.
