Before diving into pins, understand the physical layout. Most K6A ECUs use three rows of pins (A, B, C) in a 32+32+32 configuration (96-pin). Connector A is usually engine management (sensors, injectors, ignition). Connector B is power, grounds, and actuators (idle control, EGR, turbo boost solenoid). Connector C is vehicle interface (speed sensor, check engine light, tachometer, immobilizer). For those seeking more information on the Suzuki
