Where is the computer located on a 1992 Lincoln town car?

There is no computer in the sense of a central processing unit (CPU) and motherboard like in a desktop or laptop in a 1992 Lincoln Town Car. Instead, the car's electronic control systems rely on several electronic control modules (ECMs), sometimes called Engine Control Units (ECUs) or other similar names depending on their function. These are distributed throughout the vehicle.

The most important ECM would be the Powertrain Control Module (PCM), which manages the engine and transmission. This would likely be located somewhere under the hood, possibly near the firewall or attached to the engine itself. Other modules would control things like the body electronics, climate control, and anti-lock brakes and would be located in various areas. There isn't one central "computer" location.
