What does the Volvo 240 computer look like?

The Volvo 240's computer, often referred to as the engine control unit (ECU), is a compact, rectangular metal box typically housed under the dashboard or in the engine compartment. It features various connectors for wiring harnesses and may have a label indicating its part number and specifications. The design is utilitarian, reflecting the era of its production in the 1980s and 1990s, with a simple, functional aesthetic rather than a modern sleek appearance. Its casing is usually metallic or plastic, designed to withstand the automotive environment.
