⚠️ Late 1982-1985 models only; early hybrid electro-mechanical system. Limited adaptation (idle speed, mixture) via dealer tool. Most units are fixed programming with no true reprogramming capability. Aftermarket tools can read basic codes via 38-pin connector but cannot perform adaptations.
📍 Engine compartment, mounted on firewall or inner fender near distributor
⚠️ Non-programmable solid-state ignition module; purely analog switching device for coil triggering. No software, no coding. Mechanical timing adjustment only.
