The Suzuki K6A engine is a 660cc three-cylinder powerplant common in Japanese kei cars like the , Cappuccino , and Carry . Because it has been produced in many variants (turbo, non-turbo, VVT), there is no single "universal" pinout; however, most K6A ECM (Engine Control Module) setups use two primary connectors: C37 (60 pins) and E23 (34 pins) .
