Before beginning, disconnect the negative (-) terminal of the
battery prior to working on the positive (+) terminal to prevent
a short to ground. This is important, unless you want to spend
the rest of your life with a nickname like "Sparky," or "Smokey."
Reconnect the negative terminal only after all connections have
been made.
Factory Ground wire may
need to be replaced if it is
frayed or broken.
Run signal cables (RCAs)
and remote turn-on lead
down the opposite side of
the vehicle of the power
wire to avoid radiated noise.
Avoid sharp edges that
could chafe through the
insulation.
