Asked by for the 1991 Chevrolet Lumina
The electronic control module for the ignition is located under the ignition coil pack on the cylinder head. Autozone have some popular workshop manuals for free on line once you register (for free) on their website or there is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try
and get an online repair manual subscription.
