Refer to Car Owners manual for the procedure for disconnection of your

•
The vehicle battery must be disconnected during the installation procedure
except where it is necessary to carry out circuit testing specified.

Vehicles fitted with digital radios having a security code or memory feature will
require re-programming on completion of the installation.
•
Ensure you have noted the security code of your radio before disconnecting
the vehicle battery.
VEHICLE WIRING TESTING
If you are unable to easily identify the correct wire on the vehicle to make a
connection it is recommended a 12 volt test lamp or multi-meter is used. Care must
be taken to ensure that the wire being tested is not shorted out to earth by the test
lamp or multi-meter probes.
INSTALLATION NOTES
The wiring harness is supplied with an in-line (10 amp) fuse on the RED lead. If the
fuse blows, you must investigate the cause and replace with a fuse for the same
rating. When routing the harness around the engine compartment and through a
bulkhead inside the vehicle, ensure the wire’s insulation cannot be damaged on
sharp metal edges.
The harness should be concealed and protected wherever
possible by using good quality insulation tape. It is recommended that wherever
possible connection to the vehicle wiring is carried out at the steering column or at
the fuse box. This will prevent tampering from outside the vehicle.
MAKING RELIABLE CONNECTIONS
All connections in the engine bay area must be made using either solder joints or
good quality
crimp termination’s
.
WARNING: The use of Insulation Displacement Connectors such as scotchlocks
(IDC’s) is not recommended in the engine bay area. The use of IDC’s in this area
may result in the alarm failing to operate correctly or cause false alarms.
IDC connectors can be used inside the vehicle, but you must follow the instructions
below to ensure a reliable connection.
