Important Fitment & Installation Notes
Same connector does not mean same CDI. AC and DC CDI units are not interchangeable. Pinouts may differ between vehicles that appear to use the same connector; compare the wiring arrangement, original unit and dimensions before installation. Incorrect connections may prevent starting or damage ignition components. If uncertain, ask a qualified technician to verify compatibility. Results depend on engine condition and the complete ignition setup.
