Accessories/ Installation Procedure  
with the ignition, connect the ignition wire to a power  
source that can be turned on and off with the ignition key.  
Use a commercially available conversion connector if the  
connector does not fit in the vehicle connector.  
Insulate unconnected wires with vinyl tape or other similar  
material. To prevent a short circuit, do not remove the caps  
on the ends of the unconnected wires or the terminals.  
If the console has a lid, make sure to install the unit so that  
the faceplate will not hit the lid when closing and opening.  
If the fuse blows, first make sure the wires aren’t touching  
to cause a short circuit, then replace the old fuse with one  
with the same rating.  
Connect the speaker wires correctly to the terminals to  
which they correspond. The unit may be damaged or fail to  
work if you share the - wires or ground them to any metal  
part in the car.  
After the unit is installed, check whether the brake lamps,  
blinkers, wipers, etc. on the car are working properly.  
Mount the unit so that the mounting angle is 30° or less.
