Pin Number Color Description
1 (Power +) Red Positive charge of the power input, connected to the positive charge of the
vehicle battery. Input voltage: 11–36 V. 12 V is recommended.
2 (GND) Black Ground wire, connected to the negative charge of the vehicle battery or to
the negative terminal.
3 (Input 1) White Digital input 1; negative trigger (SOS button by default)
4 (GND output) Black Ground wire, connected to input 1 (SOS button)
5 (Input 2) White &
brown
Digital input 2; negative trigger
Connect to a door trigger signal cable to detect vehicle door status. (Most
Chinese, Korean, and Japanese vehicles are negative edge-triggered.)
6 (GND output) Black Ground wire
It can be used as a ground wire connected to an analog sensor.
7 (Input 3) White &
red
Digital input 3; positive trigger
Connect to the vehicle ACC cable by default to detect the vehicle ACC status.
8 (Analog input 1) Blue Analog input 1 with 12-bit resolution; valid voltage: 0–6.6 V
Connect to an external sensor, such as the fuel level sensor.
9 (Fuel level
sensor input)
Blue &
brown
Analog input 2 with 12-bit resolution; valid voltage: 0–6.6 V
There is a white plug on the AD cable, and the cable is connected to the A53
fuel level sensor by default.
10 (Output 1) Yellow Output 1
Valid: low level (0 V)
Invalid: open collector
Maximum voltage for output open collector (invalid): 40 V
Maximum current for output low voltage (valid): 400 mA
Connect to an external relay to remotely cut off the vehicle fuel cable or
engine power supply.
11 (Output 2) Yellow &
brown
Output 2
Valid: low level (0 V)
Invalid: open collector
Maximum voltage for output open collector (invalid): 40 V
Maximum current for output low voltage (valid): 400 mA
Connect to an external relay to remotely cut off the vehicle fuel cable or
engine power supply.
12 (1-Wire port) Green TTL3.3V level
Connect to the A52 digital temperature sensor or iButton reader by default
by using the A61 sensor box.
Note: The DC or AC voltage that is greater than 3.3 V is not allowed.
