Setup and Installation
Follow these steps to correctly install your FUKIN TUNED FT71 Throttle Response Controller:
- Prepare the Vehicle: Ensure your vehicle is turned off. Open the driver's side door and leave it open for at least 15 minutes. This allows the vehicle's Engine Control Unit (ECU) to fully shut down and prevent any error codes during installation.
- Locate the Accelerator Pedal Position Sensor: The sensor is typically located above the accelerator pedal.
- Disconnect the Stock Harness: Carefully unplug the factory wiring harness from the accelerator pedal position sensor.
- Connect the FT71 Unit In-Line: Connect the FUKIN TUNED FT71 unit's harness in-line with the accelerator pedal position sensor. One end of the FT71 harness connects to the vehicle's stock harness, and the other end connects to the accelerator pedal position sensor. Ensure both connections click securely into place.
- Secure the Unit: Use the provided zip ties or hook and loop fasteners to mount the FT71 unit in a safe location, away from moving parts or excessive heat.
