If the description of the fuse box is vague and cannot be judged, the corresponding harness can be found by measuring with a
test pencil. The judgment method is as follows：
Vehicle Power Harness(VIN)：When the vehicle engine turning off, use the test pencil to measure whether the VIN has
electricity. If there is electricity, you can judge that this harness is VIN, and then measure the voltage to ensure that it is within
the scope of use of the device.
Vehicle Ignition Harness(ACC)：Use the test pencil to measure ACC harness, if the voltage of this harness is 0V when the
ACC is off and the voltage of this harness is not 0V after the ACC is on, it can be judged that this harness is an ignition signal
harness. Then measure the voltage to ensure that the voltage can work normally.
Brake, Left and Right turn Signal Harness：Use the test pencil to measure the voltage, when the vehicle does not turn on
the left and right turn signal lights, the harness has no voltage, and when the vehicle turns on the left and right turn signal, the
harness has voltage;It indicates that this harness is left and right turn signal harness; Braking is the same. If you still cannot
determine the signal harness through the above methods, please contact the team or other professional auto repair shop for
assistance.
According to different customer needs, other unused harnesses, such as can wires, are not required to be disconnected, but
must be wrapped with insulating tape to ensure that the exposed part of the wire head does not contact any part of the vehicle

Installation and wiring
In order to improve the operation reliability and prolong the service life of the device, the installation mode and location should
be comprehensively considered from the aspects of vibration resistance, heat dissipation, moisture resistance, dust
prevention, damage prevention, electrical environment, wiring and maintenance.
1)Direction: the longitudinal axis of the device and the longitudinal axis of the vehicle are basically the same (the deviation is
not more than 20 °), The front panel of the device faces the inside of the vehicle and is firmly fixed by using the bracket
method or the slot installation method (as shown in Figure 5)
Notice：Because the IMU module of AI-8-BOX is located inside the host, failure to install and calibrate as required will affect
the relevant alarm functions of the IMU, including ADAS, BSD,Acute driving detection and other functions
Device’s GND connects to
vehicle GND position
