Step 1 Connect the fuse box

Select a suitable car fuse box based on the wiring path and the location of the main device, and connect it to the hardwire kit. Please ensure that the fuse box can contain the followings:

1. Regular electric fuse with an output voltage of 12-30V and output current of 2.4A;
2. ACC power fuse.

Step 2 Connect the hardwire kit to the fuse box

Connect the wires of the hardwire kit to the fuse box in the following way:

1. Connect the power cable (red) to the regular electric fuse with an output voltage of 12-30V and output current of 2.4 inside the fuse box;
2. Connect the ACC signal cable (yellow) to the ACC power fuse inside the fuse box;
3. Connect the ground wire (black) to the negative terminal or ground of the fuse box.

Important notes:

• The actual installation and wiring path of the hardwire kit may differ from the illustrations in the manual. Please seek assistance from a professional technician.
• Before installation and wiring, please turn off the car engine and power to prevent short circuit.

Step 3 Test the connection and ACC signal

Please follow the steps below to test the connection and ACC signal:

1. Connect the USB port of the hardwire kit to the power outlet of the main device (DC/IN). Start the engine and wait for the main device to turn on. If the main device fails to power on, press and hold the power button to manually turn it on. If the message “Connect to an external power source” is shown, check the power cable of the hardwire kit to see if it is correctly connected to the regular electric fuse.
2. After the main device is turned on, go to Settings > Power on/off settings and select ACC detection mode. Restart the main device for the new settings to take effect.
3. After the main device has restarted, turn off the engine and remove the key. Check if the main device powers off or enters sleep mode. For some cars, the ACC power off signal will only be triggered when the driver seat door is opened after the engine is turned off. Some car models will only trigger the ACC power off signal after the engine has been turned off for a certain period of time. For such cars, observe for some time after the ACC power is turn off to check if the main device powers off or enters sleep mode.
4. After the main device powers off or enters sleep mode, restart the engine and check if the main device automatically turns on.

The above steps show that the connection is correct and that the ACC signal can be triggered correctly.

Please follow the steps below to test the connection and ACC signal:

1. Connect the USB port of the hardwire kit to the power outlet of the main device (DC/IN). Start the engine and wait for the main device to turn on. If the main device fails to power on, press and hold the power button to manually turn it on. If the message “Connect to an external power source” is shown, check the power cable of the hardwire kit to see if it is correctly connected to the regular electric fuse.
2. After the main device has turned on, turn off the engine and remove the key. Check if the main device powers off or enters sleep mode. For some cars, the ACC power off signal will only be triggered when the driver seat door is opened after the engine is turned off. Some car models will only trigger the ACC power off signal after the engine has been turned off for a certain period of time. For such cars, observe for some time after the ACC power is turn off to check if the main device powers off or enters sleep mode.
3. After the main device powers off or enters sleep mode, restart the engine and check if the main device automatically turns on.
   The above steps show that the connection is correct and that the ACC signal can be triggered correctly.
   If the connection or ACC signal test fails, please check the wiring of the hardwire kit and ensure that the fuse and ground are correctly connected. If the connection is correct, but the test fails, contact after-sales service for assistance.
   After ensuring that the connection and ACC signal are correct, go to the next step: “Cable management”.

Step 4 Cable management

Route the hardwire kit to the location of the main device. If the hardwire kit is too long, tie it up, but do not cut it. Cutting the hardwire kit will affect the power and ACC signal to the main device.
