line up with the bulkhead grommet and the
clips in the engine compartment. Route the
cable as noted during removal.9On completion, pull the speedometer cable
from within the engine compartment to ensure
that the cable is straight between the
instrument panel and the bulkhead grommet.

that the motor operating rod engages with the
lock lever.
Note: The alarm system has a self-diagnosis
function, which allows a Ford dealer to carry
out fault diagnosis, using suitable specialist
equipment. In the event of a problem with the
alarm system, it is advisable not to tamper
with the components until appropriate fault
diagnosis has been carried out.Location
1From 1990, certain models are fitted with
an anti-theft alarm(see illustration).
2The alarm system consists of a control
module mounted behind the driver’s side
facia; trip switches fitted to the doors,
tailgate/boot lid, and bonnet; activating
switches fitted to the front door locks; an
additional horn mounted at the bulkhead next
to the battery and an indicator light mounted
on the top of the facia.

4Release the carpet trim panel from under
the driver’s side facia. 5Reach up behind the facia and locate the
control module. Release the plastic retaining
clips using a screwdriver, and lower the

Removal
1Disconnect the battery negative lead.
2Remove the seat.
3Remove the seat cushion trim or backrest
trim as necessary.
4Note which way round the pad is fitted,
then remove the wire clips and adhesive tape

rod and fit it to the new pad.
Refitting
5Fit the new pad with the thermostat facing
the cushion foam(see illustration).Secure
the pad with wire clips and tape, making sure
that it is not too tight - it must be able to flex
when sat on.
6Refit the cushion or backrest trim, as
applicable, being careful not to trap or kink
the pad.
7Refit the seat, reconnect the wiring and
check the pads for correct operation.

2Remove the right-hand side trim panel from
the luggage compartment.
3Working outside the vehicle, unscrew the
nut and remove the spacer and seal from the
base of the aerial.
4Working inside the luggage compartment,
either unscrew the aerial bracket securing
screw and slide the bracket from the aerial
tube, or pull the base of the aerial from the
rubber bush in the bracket, as applicable (see
illustration).
5Ensure that the aerial is fully retracted, then
pull it through the hole in the bodywork into
the luggage compartment (see illustration).
6The aerial lead may be a push-fit in the
base of the aerial, or may be secured by a
knurled nut. Disconnect the aerial lead and
where applicable, disconnect the wiring from
the electric motor. Note that the aerial lead
runs through the roof. If it is necessary to
renew the lead, it may prove easier to leave
the old lead in place and run a new one under
the carpet. Follow existing wiring runs where
possible.

carefully prise the base seal from the roof
panel.
16The aerial lead runs across the roof panel
under the headlining, and down the right-hand
front pillar to the radio unit. Renewal is
straightforward, but the front section of the
headlining must be released for access and a
length of string should be tied to the end of
the aerial lead before removal to aid routing
when refitting.
17The aerial rod can be renewed by simply
unscrewing it from the base.
