For enthusiasts looking to extract more power from the L9's engine (especially the EF-DET turbo variant), understanding the ECU pinout is critical. Many owners opt for a (e.g., GReddy e-Manage) or a standalone ECU . When adding performance modifications:
Once you have your diagrams, you can begin tackling common problems. These issues often have standard "fingerprints" that a wiring diagram can help you identify.
This is a common area for troubleshooting "Crank No Start" issues. wiring diagram daihatsu l9 ecu pinout

The wiring diagram for the Daihatsu L9 is a complex document that illustrates the electrical connections between various components of the vehicle's electrical system. The diagram shows the relationships between the ECU, sensors, actuators, and other electrical components. The wiring diagram is essential for troubleshooting electrical issues, installing aftermarket accessories, and modifying the vehicle's electrical system.
When identifying wires in the harness, you may encounter these common color codes used in the L900/L902 series: Speed signal to ECU. Yellow/Black: Check Engine Light. Red/Yellow: RPM (Tachometer) signal. Blue/Yellow: Fuel gauge. White/Black: Common Ground. Critical Resources for Verification Includes pins for the Knock Sensor (KNK), Coolant
Daihatsu uses a standard color-coding system to identify circuit paths: auto-detal.ru Single Color : Represented by a single letter (e.g., for Black, for White, Composite Color : A basic color with a secondary stripe (e.g., for Blue with a White stripe). auto-detal.ru Resources for Full Diagrams Comprehensive circuit diagrams, including the Junction Block (J/B) Power Distribution System , are often required to trace full harnesses.

Daihatsu L9 (specifically the Move or models with JB-DET/EF engines), the ECU pinout varies slightly between versions (e.g., cable type vs. electronic throttle), but standard configurations often include critical signals for engine management and dashboard integration. Core ECU Pinout Signals (EF/JB-DET)
Depending on the production year, region (JDM vs. Export), and transmission type (Manual vs. 4-speed Automatic), Daihatsu utilized two distinct ECU casing styles: Speed Signal to ECU: Light Green with Red stripe
Trigger signal sent by the ECU to close the EFI main relay circuit. E1 / E2 (ECU Grounds): Main chassis ground connections.
Daihatsu L9 (specifically the L900 series, commonly known as the Move), the ECU pinout and wiring depend significantly on the engine type—most commonly the (1.0L) or the
(660cc Turbo). These diagrams are essential for tasks like engine swaps, aftermarket ECU installation, or OBD-II port integration. Core ECU Pinout Details (L9 JB-DET Turbo)
If you are performing a conversion (like a Kancil L5/L6 to L9 swap), the meter and indicator signals are often color-coded as follows: Signal Function L9 Wire Color Related System Check Engine Black/Yellow EFI Diagnostics RPM (Tacho) Red/Yellow Engine Speed Speed Signal Light Green/Red Speedometer to ECU Water Temp Temperature Gauge Oil Pressure Low Pressure Warning Battery/Alt Charging Indicator Useful Wiring Resources
