NOTE: While checking the operation of the
fusible link, loosely connect the battery-
terminal only, to safeguard against damage
to the wiring harness.
(5) If the circuit is still inoperative or the fusible
link burns out again, refer the problem to an auto-
motive electrician.
RELAY LOCATIONS
The various relays employed in the vehicle elec-
trical system are located behind the fusible links
adjacent to the washer bottle in the engine compart-
ment, on the engine compartment bulkhead, under
the windscreen wiper motor and in the fuse box at the
lower right hand side of the dashboard.
The engine compartment relays power the radia-
tor fan, horn, condenser fan, bulb check, automatic
transaxle neutral safety switch, air conditioner and
condenser motor.
Installed view of the fuse box relays.
The fuse box relays power the fuel pump, ignition,
some accessories and the el ectronic control module.
18. TRAILER WIRING
There are several brands of trailer wiring connec-
tors available with a variet y of pin configurations. The
most common is the seven pin type which provides
for two auxiliary circuits, usually used for reverse
lamps and electric trailer brakes.

When installing a trailer socket, it may be neces-
sary to replace the original vehicle flasher unit with a
heavy duty unit to maintain the flash rate in accor-
dance with local regulations. Local regulations may
also require the installation of a dashboard mounted
repeater lamp.
Should the trailer socket and plug not be matched,
adaptors can be made or obtained to facilitate con-
nection.
TO INSTAL TRAILER SOCKET.
The minimum materials required are a trailer
socket, mounting bracket, seven core flex, insulated
wiring connectors and a rubber grommet.
(1) Disconnect the negative battery terminal.
(2)Locate the wiring harness for the lamps at
the rear of the vehicle.
For five pin sockets and plugs, use the following
standard trailer wiring code:
Terminal No.CircuitColor2 Left turn signal lampYellow
3Earth White
5 Ri

6Stop lamp Red
7 Tail lam

Minimum material needed for wiring up a trailer.
Utilux trailer socket and plug shown.
(3) Identify the wires for the right turn signal
lamp, left turn signal lamp, tail lamp, stop lamp,
reverse lamp and earth. Use the vehicle wiring
diagram in this section to determine the wire color
for each lamp circuit.
(4)Connect the seven core flex to the various
lamp wires using insulated connectors.
For seven pin sockets and plugs, use the following
standard trailer wiring code:

2 Left Turn Signal Lamp Yellow
3Right Turn Signal LampGreen
4 Stop LampRed
5AuxilaryBlue
6 Earth White
(5) Drill a suitably si
zed hole through the vehicle
floor and install a rubber grommet to the hole.
NOTE: Before drilling the hole, check
whether there is an existing hole which may-
be used. Ensure that a rubber grommet is
installed to prevent chafing of the wires.
Pass the seven core flex through the rubber
grommet. Cut the seven core flex to the required length
and slide the dust cover onto the flex. Remove approximately 15 mm of insulation
from each wire in the flex.
Connect the wires of the seven core flex to
the terminals of the socket, using the standard wiring
code and following the socket manufacturers connec-
tion procedure. Assemble the socket and install the dust cover
to the rear of the socket. Install the mounting bracket as close as
possible to the tow bar ball and high enough to
maintain vehicle ground clearance. Install the socket to the mounting bracket.
Connect a trailer plug to the socket and test
for correct lamp operation.
TO INSTAL TRAILER PLUG
The minimum materials required are a trailer
plug, seven core flex and insulated wiring connectors.
The installation procedure for the trailer plug is
similar to that for the socket with attention to the
following points:
Connect the trailer wiring to the plug accord-
ing to the standard wiring color code and the plug
manufacturers instructions. Use a suitable length of
seven core flex and insulated connectors should the
trailer wiring not be long enough.
If the trailer wiring does not conform to the
standard color code, identify each circuit as follows: (a) Locate the trailer earth wire.
PLUG

218 Electrical System
Connect a jumper lead from the negative
terminal of a 12 volt battery to the earth wire. Connect a jumper lead from the positive
terminal of a 12 volt battery and connect each of the
trailer lamp wires in turn to the positive battery terminal jumper lead, noting the color of the wire
and the lamp circuit operated.
(3) After installation, connect the trailer plug to
the socket on the vehicle and check for correct lamp
operation.
Vehicle and trailer wired to conform to Australian Standard AS2513. Sockets and plug shown are as viewed
from the terminal side of the component. Refer to the text for the correct terminal applications when using a
5 or 6 pin socket and plug.

1. WINDSCREEN AND REAR GLASS
The renewal or replacement of the windscreen
and the rear glass follows the same basic procedure.
The successful installation and sealing of the
windscreen or rear glass will depend to a large extent
on the technical knowledge and experience of the
operator and it is not recomm ended that rear glass or
windscreen replacement be attempted by anyone
lacking in previous experience.
