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:

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:

(5) Drill a suitably sized 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

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.
