4. Installation

For the installation, the electric cable must be disconnected from the
module and the vehicle's battery. It is very important that the cable
length is the shortest possible and that exceeding unused parts of wires
are cut off. Never roll up the excess of any wire in the cable; by doing
so, interference problems, which are very usual with any electronic
device, are avoided.
The electric cable must be protected from contact with sharp parts
on the vehicle's body that might damage the wires and cause short
circuit. Be particularly attentive to wires passing through holes, and use
rubber protectors or any other kind of protective material to prevent
any damage to the wires. At the engine compartment, pass the wires
through places where they will not be subject to excessive heat and
will not obstruct any mobile parts in the engine. Always, when possible,
use plastic insulation on cables.
