that a BUS cable with an 8-pin plug (L-type)
cannot be used because of its shape.

Installing the unit
•Mount the unit either inside the trunk or under a seat.
•Choose the mounting location carefully so the unit will not interfere with the normal movements of
the driver and it will not be exposed to direct sunlight or hot air from the heater.
•Do not install the unit under the floor carpet, where the heat dissipation from the unit will be
considerably impaired.
First, place the unit where you plan to install it, and mark the positions of the four screw holes on
the mounting surface.
Notes
• Use only the supplied screws.
• Be sure not to damage the fuel tank or brake line with the tapping screws.
Fuse replacement
If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after
replacement, there may be an internal malfunction.
Warning
Use a fuse with the specified amperage rating.
Use of a higher amperage fuse may cause serious damage.
