the car battery positive terminal + and the
ground wire to the car body.
! This unit is for vehicles with a 12 V battery and
negative grounding. Before installing in re-
creational vehicles, trucks or buses, check the
battery voltage.
! When installing this unit, make sure to con-
nect the ground wire first. Ensure that the
ground wire is properly connected to metal
parts of the car's body. The ground wire of the
one of this unit must be connected to the car
separately with different screws. If the screw
for the ground wire loosens or falls out, it
