.•  Do not connect Battery wire (yellow) and Ignition wire (red) to the \
car chassis or Ground wire (black) to prevent a short circuit.
•  Insulate unconnected wires with vinyl tape to prevent a short circuit.
•  Be sure to ground this unit to the car’s chassis again after installa\

•  Mount the unit with the angle of 30° or less.
•  If your vehicle wiring harness does not have the ignition terminal,  connect Ignition wire (red) to the terminal on the vehicle’s fuse b\
ox 
which provides 12 V DC power supply and is turned on and off by the 
ignition key.
•  After the unit is installed, check whether the brake lamps, blinkers,  wipers, etc. on the car are working properly.
•  If the fuse blows, first make sure the wires are not touching car’s  chassis, then replace the old fuse with one that has the same rating.
