 CAUTION
s Verify wires with a digital multi-meter 
prior to making any connections. 
Many new vehicles use multiplexed 
and/or low voltage circuits that can 
be damaged if a test light or logic 
probe is used.
s Connect cables appropriately. If a 
wrong connection is made, this may 
cause a fire or accident.
s When passing cables through 
the body of the vehicle, use non-
conductive grommets.
If the coatings of the cables are 
worn out by rubbing, this may cause 
an accident, fire or a short circuit.
s After wiring cables, fix them with 
insulation tape.
s Be sure to switch off the vehicle 
when connecting or disconnecting 
cables to/from the unit, otherwise 
an electric shock, injury or accident 
may occur.
