6 Installations
WARNING: Failure to closely adhere to installation instructions may result in
system malfunction and ultimately compromise the reliability of the entire
system.
It is assumed that installers are familiar with vehicle wiring and auto electrical
devices.
This chapter contains a selection of wiring options. Select the options best
suited to your application.
Wiring considerations and safety guidelines
Always adhere to safety instructions to prevent possible injury and avoid
damage to existing vehicle systems.
Before beginning an installation, disconnect the vehicle battery. Notify the
client that this erases the memory of all auto systems. It will have to be re-
programmed.
Test the wiring only by using a LED test lamp or a voltmeter. Using other types
of test lamps may cause high output currents and significant damage to the
vehicle's electrical systems.
Solder all the connections created during installation and insulate them using
the electrical insulation tape and/or insulation sleeves. Twisting wires together
without soldering them can result in loose connections and serious failures.
There is the danger of explosion if the battery is incorrectly replaced. Replace
the battery only with the same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer's
instructions.
Take special care to avoid damage to the cables of the vehicle's security
systems, such as vehicle computer and air bags. Take note of this when testing
voltage using a voltmeter or test lamp to prevent undesired system activation.
Only trained and qualified personnel should install, replace, and service the
equipment.
When drilling the vehicle, verify that there are no cables in the vicinity. Failure
to do so may result in severe damage.
Install a 5 A fuse on the Ignition and Main Power connections.
