Unlike most Pre-OBDII or OBDI Diagnostic Connectors that are found in the engine bay, the GM OBDI ALDL or ALCL connector is located under the dash on the driver’s side of the car (but not always). The most common type of ALDL/ALCL connector was the 12 pin connector.
General Motors was one of the few manufacturers that located their early OBD-I assembly line data link (ALDL) connector next to the steering wheel.
It was not until the emergence of OBD-II systems that other automakers followed suit, eventually moving their data link connectors (DLC) inside the passenger compartment within 16 inches of the steering column.
