| Pin | Wire Color | Function | Notes | |------|------------|----------|-------| | B01 | Blue/Red | Starter Signal (ST) | 12V only while cranking. | | B02 | Light Green | Power Steering Pressure Switch | Idle-up request. | | B03 | Black/White | Vehicle Speed Sensor (VSS) | Digital square wave (4 pulses/rev). | | B04 | Brown/White | A/C Compressor Relay | ECU disables A/C at WOT. | | B05 | Purple | A/C Idle-Up Request | Activates IAC for A/C load. | | B06 | Orange | Radiator Fan Relay Low Speed | Output to fan control module. | | B07 | Orange/Black | Radiator Fan Relay High Speed | Direct ground for high speed. | | B08 | Green/Black | Intercooler Water Pump (if present) | Some turbo Wagon R models. | | B09 | White/Blue | Ignition Feedback (IGF) | Confirms coil firing. No signal = stall. | | B10 | Red/Yellow | Engine Speed Output (to tachometer) | Signal for dash tach. | | B11-22 | Various | Empty or model-specific | e.g., 4WD vacuum solenoid, shift light. | Then connect your gauges: tach (B10), temp (A19),

Suzuki K6A ECUs typically use a multi-connector system. The number and type of connectors are one of the first major physical differences you will see:

The K6A's ECU (Electronic Control Unit) is the brain of the engine, receiving data from various sensors (input) to precisely control actuators (output). It's vital to know that pin assignments can vary depending on the vehicle model (e.g., Alto, Wagon R, Carry, Jimny) and the ECU part number. Always verify your specific ECU part number first.
