For diagnostic and sensor voltage data (e.g., MAP sensor 4.5–5.5V), refer to the Daihatsu EJ-VE Engine ECU Manual to narrow down the exact pin locations? EF Engine ECU Pinouts - DIY or TECHNICAL - Live To Dai Blue/Yellow: Fuel gauge
The L9 typically uses a multi-plug configuration, often consisting of a 26-pin and a 16-pin connector. Below is a common terminal arrangement found in these units: Live To Dai Power & Ground : Main battery power input (12V). E1 / E01 / E02 : Earth/Ground terminals. : Backup power supply for memory. Sensors (Inputs) : Engine coolant temperature sensor. : Knock sensor signal. : Vehicle speed sensor. : Intake air temperature. Actuators (Outputs) : Fuel injector control signal. ISC / ISCV : Idle speed control valve. : Fuel pump relay control. : Ignition signal. Live To Dai Wire Color Identification
