This is an original equipment manufacturer (OEM) Honda Motorcycle Ignition Control Module, commonly known as a CDI box, ECU, or igniter unit. It controls spark ignition timing to support efficient combustion, smooth throttle response, and reliable engine operation. The module uses a durable composite plastic housing with internal sealing to protect the electronics from heat, vibration, and moisture. A factory-style multi-pin connector provides direct connection to the motorcycle wiring harness. Physical Stamp Markings: MY5A / 821Z / 0119 Vehicle Compatibility This MY5A 821Z ignition module is designed for full-power Honda CB500 PC32 models. * Honda CB500 Standard / Naked (PC32) — 1996–2003 * Honda CB500S Sport / Half-Fairing (PC32) — 1998–2003 Please compare the stamp markings and connector layout with your original module before purchase, as some earlier PC26 and restricted versions may use different units.
