Wiring of Standard Version
Tips for finding right wires:
1. Use multimeter to find out the positive and negative sides of vehicle
battery.
Note: No matter the ignition key is switched to ON or OFF, current
battery voltage can be shown in the multimeter.
2. The way to find ACC wire: Connect multimeter’s black probe to
negative side, and connect red probe to a random wire, at this
moment, the voltage shown in multimeter is 0V; turn the key to ON,
if the supply voltage is shown, that’s the correct ACC wire.
3. Connect the two connectors together, if the vehicle has no
connector, please connect device’s wires to corresponding vehicle
wires.
