Used in newer K6A variants (e.g., Yellow/Green and Gray/Yellow) for vehicle-wide communication. Suzuki K6a Ecu Wiring Diagram Pdf
If your engine is a "Twin Cam" (DOHC) with VVT, you cannot simply ignore the oil control solenoid wiring. The ECU expects to see the camshaft position sensor signal and control the solenoid. If the VVT solenoid is unplugged or miswired, the engine may run in a "limp" mode with retarded timing, killing low-end torque.
