Red wiring is not for all models, but if the OEM radio harness of your vehicle does not have an ignition wire, the aftermarket stereo cannot be turned off/on through the OEM radio harness; To solve this problem, you need to get a 12 v power supply from the ignition by running the red cable separately from the factory radio harness
