Is there any difference between ON1 and ON2? how to choose?ON1 and ON2 are the same. If the original car has 2 ON, connect ON1 and ON2 respectively, regardle of the order.If there is only one ON in the original car, connect ON1 or ON2.2. Blue ACC, what does power off at startup mean? How to connect it?Blue ACC, it will automatically power off when the engine starting. Most of the car's own ACC will also power off when the engine starting. If your car does not have ACC, there is only 1 or 2 "ON". If so, we do not need to connect blue ACC; if your car does not have ACC, but has an "ON" engine starting will power off, if so, we can incorporate blue ACC into ON1 and then connect to the car.3. Can't start the engine remotely?In the locked state, pre "Lock" or "find" 3 times in a row to start the engine remotely. Make sure the operation is correct, if there is no feedback, the gray handbrake wire, it must be connected correctly, it can be grounded. Maybe the car itself needs to hit the brakes to start the engine, you need to connect an extra wire to the yellow start wire of the module, and then this wire is connected with a diode (single guide), and then connected to the brake signal wire of the car;4. How to use the app?First, scan the code to download the APP, (choose Android or Apple), then turn on the Bluetooth of your mobile phone, Log in to the APP, ID and paword on the Bluetooth module (different IDs for each Bluetooth module).
