3. Setup and Installation
Before installation, ensure the vehicle's power is off and the battery is disconnected. This kit is designed for DIY modification and requires careful attention to wiring connections. Refer to the provided wiring diagrams and ensure all connections are secure.
3.1. Control Box Compatibility Check
To confirm compatibility, open your existing electric ride-on car and locate its control box. If the appearance and connector types of the weelye control box are similar to your original unit, this kit should be compatible. This kit is specifically designed for 24V systems.
3.2. Wiring Connections
The kit features one-button installation sockets for battery and motor cables, simplifying replacement and maintenance. Connect the components as follows:
- Connect the Control Box to the 24V Battery (not included). Ensure correct positive (+) and negative (-) polarity.
- Connect the Drive Motors to the designated motor ports on the Control Box.
- Connect the Accelerator Pedal to its corresponding port.
- Connect the Power Switch, High/Low Speed Switch, and Forward/Stop/Back Switch to the main wiring harness.
- Connect the Overload Protector (Self-resetting fuse) in line with the power circuit as indicated in the wiring diagram.
- Connect the Charging Port to allow for external battery charging.
- If applicable, connect the Steering Motor and Music/Light Interface to their respective ports.

4. Operating Instructions
4.1. Remote Control Frequency Matching (First Use or Battery Replacement)
The remote control must be paired with the control box for proper operation. Follow these steps:
- Install Batteries: Open the remote control's battery compartment. Install two AAA 1.5V batteries, ensuring correct positive and negative polarity. Close the battery cover. The indicator light will flash three times, confirming correct battery installation.
- Initiate Pairing: Press and hold the "Frequency Key" (often labeled "Car Select" or "S" for Speed) on the remote control for approximately 2 seconds. The indicator light on the remote will begin to flash.
- Power On Vehicle: Turn on the power supply of the electric ride-on car. The indicator light on the remote control should turn off, indicating successful frequency matching.
- Verify Operation: Test the remote control's functions (forward, backward, turning) to ensure proper pairing.
Note: If the indicator light on the remote does not turn off (matching unsuccessful), turn off the car's power supply and repeat steps 2 and 3.

4.2. Remote Control Button Descriptions
- Forward (△): Moves the car forward.
- Backward (▽): Moves the car backward.
- Turn Left (◁): Turns the car left.
- Turn Right (▷): Turns the car right.
- Speed (S): Cycles through available speed settings (High, Medium, Low).
- Emergency Brake (P): Activates the emergency brake, stopping the car. Press again to release.
If the remote control is left without operation for 10 seconds, the indicator light will turn off, and it will enter power-saving mode.
4.3. Vehicle Operation
- Power On: Use the main power switch on the vehicle to turn it on.
- Speed Selection: Use the high/low speed switch on the vehicle or the 'S' button on the remote control to select the desired speed.
- Direction Control: Use the forward/stop/back switch on the vehicle or the directional buttons on the remote control to move the car.
- Accelerator Pedal: The vehicle's accelerator pedal provides direct control when not using the remote. The control box features a slow-start function for smooth acceleration.
5. Maintenance
- Battery Care: Ensure the 24V battery (not included) is charged according to its manufacturer's instructions. Disconnect the battery when the vehicle is not in use for extended periods.
- Wiring Inspection: Periodically check all wiring connections for looseness or damage. Secure any loose connections and replace damaged wires immediately.
- Component Cleaning: Keep the control box and other components free from dust, dirt, and moisture. Use a dry cloth for cleaning.
- Overload Protector: The kit includes a self-resetting fuse (overload protector). If the vehicle stops unexpectedly, check for an overload condition. The fuse will reset automatically once the condition is resolved.
