Finding a precise wiring diagram and ECU pinout for the Daihatsu L9
series (commonly the Daihatsu Move L900/L902/L910) involves identifying your specific engine model, as pinouts differ significantly between the EF-VE (Naturally Aspirated) and EF-DET or JB-DET (Turbo) variants . Detailed technical guides and schematics are often archived on platforms like Scribd and enthusiast forums such as Live To Dai . Common ECU Pin Functions for L9 Series
Most Daihatsu EFI systems from this era share a core set of terminal labels. When inspecting the ECU connectors (typically from the wire side), you will often find these critical pins: Power & Ground: BATT / +B: Constant battery power for memory . IGN / IG1: Switched ignition power to activate the ECU . E1 / GND: Main chassis ground for the control unit . Sensor Inputs: PIM: Intake manifold pressure (MAP sensor) signal . THW: Engine coolant temperature signal . VC: 5V reference voltage output for sensors . SPD: Vehicle speed sensor input . Control Outputs: #10, #20, #30: Fuel injector trigger signals. IGT / IGF: Ignition trigger and fail-safe feedback signals. FP: Fuel pump relay control . Wiring & Inspection Tips
Connector Layout: Always verify if the diagram is viewed from the wire harness side or the ECU terminal side, as they are mirrored . wiring diagram daihatsu l9 ecu pinout
Color Codes: Daihatsu typically uses standard Japanese color coding. For example, W is White, B is Black, L is Blue, and Br is Brown . Composite colors (e.g., R-W) indicate a primary color with a secondary stripe
Diagnosis: You can often find full repair manuals, such as the EJ-VE EFI System Manual
, which provides step-by-step procedures for measuring terminal voltage using a multimeter . Finding a precise wiring diagram and ECU pinout
Model Variations: The L902S (JB-DET) is a 4-cylinder turbo, while the L900S (EF-VE/DET) is a 3-cylinder. Ensure your pinout matches the cylinder count of your engine to avoid wiring errors .

This report provides a practical ECU pinout and wiring overview for a Daihatsu L9 (assumed L9-series engine/ECU). It includes assumed connector layouts, common signal descriptions, wiring colour conventions, diagnostic connections, and safety notes for testing and repairs. If your vehicle differs (model/year), specify it for exact pin numbering.
Note: Always verify with a multimeter. Pin locations can vary between Automatic (A/T) and Manual (M/T) transmissions.
