 Detail Instruction:
1.power supply: Reversing light for rear sensor
                Braking light for front sensor
                Ignition power to main box
                Gnd to Gnd
2.working detail: when begin driving, the ignition power is on, the main box is on. But if there are not any braking and reversing, the display not working.
when reversing the car, the rear 4 sensor are working, the detection range is 0.3m*2.0m
