ACC  可以看保险盒上面的 盖子上面的 丝印，  比如阅读灯，点烟器，或者 车窗，点火开关都可以当做ACC使用，用万用表测试，车辆点火启动后才有电流通过


B+，可以看保险盒上面的 盖子上面的 丝印，如果写有B+，那就直接使用。如果没发现 ，用万用表测试，在停车完全熄火状态，如果测试有电流，就可以当做B+

Gnd  ，就是地线，搭铁就可以了


How to search for ACC, B+constant power, GND


ACC can be viewed by the silk screen on the cover of the fuse box, such as reading lights, cigarette lighters, or windows. The ignition switch can also be used as ACC, and a multimeter can be used to test it. Only after the vehicle is ignited and started can there be current flowing through it


B+, you can see the silk screen on the cover of the fuse box. If it says B+, then use it directly. If not found, use a multimeter to test and stop the engine completely. If there is current during the test, it can be considered as B+

Gnd, it's the ground wire, just ground it
