Installation and Checking Installation and Checking
Connect the negative cable (black) to the vehicle ground cable
(Ensure the cable is effectively grounded)
Connect the red cable to a regular electric fuse
Connect the yellow cable to the ACC fuse
Do not reverse the connections.
Follow the instructions below to determine the
interface (red cable) when the ignition is switched off:
1、Use a multimeter to
identify a 12V interface when
the ignition is switched off.
Note: Some vehicle models have a "delayed power-off" function for the
fuse interface. To ensure the VCC regular power interface is correct, it is
necessary to open the door when the ignition is switched off, turn the
door lock to the locked position, use the key to lock the vehicle (into a
simulated locked state), and then wait for 5 to 10 minutes before identify-
ing an interface with a voltage of around 12V (A known model: BMW 525).
To determine the ACC interface (yellow cable),
please follow these steps:
1、Use a multimeter to identify 2 to 3 12V interfaces
when the ignition is switched on, and remember the
positions of these standby interfaces.
2、Switch off the ignition and use a multimeter to
measure these 2 to 3 interfaces. Connect the ACC
cable (yellow) to an interface that has no voltage. If
there is no such interface, repeat the previous step.
