What does ACC position mean?

[Carvalho]

The car ACC wire is located in the car's fuse box. Open the car's fuse box, turn off the power to the entire vehicle, and the dashboard will go dark. Locate the yellow fuse inside the fuse box and test it with the tip of an electric pen to check if the circuit has power. When the entire vehicle is powered on, if the yellow fuse on the electric pen lights up, it can be confirmed as the ACC wire. ACC wire function: The ACC wire is the power-on wire, meaning it connects to the ACC power wire controlled by the key. When the key is in the ACC position, i.e., when the ACC wire is connected, some of the vehicle's electrical devices, such as the radio and audio system, are powered on, but other components of the vehicle are not yet powered. ACC wire connection method: Locate the position of the car's ACC wire, then fix the daytime running lights in the corresponding position, and you can start the wiring process. Connect the black wire to the ground or the negative terminal of the battery; connect the red wire to the ACC relay; connect the two white wires to the headlight fuse; connect the two yellow wires (or one yellow and one green) to the positive terminal of the turn signal. After installing the wiring harness, recheck to ensure there are no loose connections.
