8) Install wires in a secure fashion so they will not be susceptible to damage from
moving parts and will maintain their position over time.
9) Make sure that the proper wir
e gauges for the circuits and devices installed are
used.
10) Test every wire connection and circuit before moving onto the next one.
11) Always confirm that the “ground” points that you select are truly “ground”. A
good ground connection will measure le
ss than 0.1 Ohm.
12) Know what wires you are tapping into. Never tap into wires that are coming
from a “black box”. This may be a sensitive computerised device, such as an
engine control computer.
13) When making connections in the fuse box, be careful t
o avoid any circuits
labelled Electronic Fuel Injection, Electronic Ignition, Electronic Ride Control, Anti
-
lock Brakes, or Passive Restraint System. Some of these circuits can be very
sensitive and should be left alone.
14) When installing additional sir
ens to any security system, always connect the
main (or first) siren directly to the security system’s output. Then connect the other
sirens (internal, external, or backup) through a relay. (Typically, alarm modules allow
for a 3 amp siren current draw. If
you connect more than one siren direct to the
alarm you may damage the siren output transistor.) The relay power must be
supplied from a separate fused supply from the fuse box. This technique will ensure
that the main siren will continue to function even
if additional sirens are shorted or
defeated.
15) Always make sure the mounting area of a device or component is safe from
contamination by water or heat, as well as from intentional damage or unintentional
damage by a mechanic performing routine mainten
ance.
16) If a problem persists try another “good” module to see if the problem is the
product or the installation.
These simple rules are ingrained in the minds of good installers. They have learned
over time that when you consider all the different con
sequences of the installation
during each step, the job goes smoother, works better, and best of all does not
come back!
