• Always use the recommended battery and ground
wire, which is sold separately. Connect the bat-
tery wire directly to the car battery positive termi-
nal (+) and the ground wire to the car body.
• Recommended wires size (AWG: American Wire
Gauge) is as follows. The battery wire, the
ground wire and the optional direct ground wire
must be same size.
