This specialized ALDL OBD2 to USB cable is engineered for owners of 1994 and 1995 General Motors OBD1 vehicles, particularly Camaros, Firebirds, Corvettes, and other LT1-equipped cars. It also supports newer Australian Holden and Commodore models that utilize a 16-pin OBD2 style connector. If your classic GM vehicle or imported Holden/Commodore features the 16-pin OBD2 diagnostic port under the dashboard, this cable provides the most user-friendly interface to your car’s ECM/PCM (Engine Control Module/Powertrain Control Module). Simply locate the port and plug in for seamless communication.
Before ordering, it’s crucial to verify the connector type under your dashboard, especially for 1994-95 vehicles. Refer to our GM OBD1 home page for detailed diagrams and references illustrating different connector styles, or consult the OBD2 diagram below for visual guidance. These specific 94-95 models with the 16-pin OBD2 style connector are unique because they supply +12V power on pin 16 and ground on pin 5. The essential 8192 baud serial data transmission is routed through pin 9 within these connectors.
Beyond basic diagnostics, this 16-pin USB ALDL cable expands functionality to instrument cluster programming for specific models like the 2004-2006 Pontiac GTO. As detailed in our instrument cluster programming software instructions, users can customize features such as RPM-based shift light activation, cluster logos, and shutdown text displays. This opens up possibilities for personalization and performance tuning. Further exploration with other newer GM cars and trucks may reveal additional software-driven modifications for instrument dash cluster reprogramming, encouraging innovation within the GM enthusiast community.
It’s important to understand that while these 1994-95 vehicles utilize the OBD2 style connector, they operate on OBD1 ECM/PCM systems internally. For owners of 1996 and later true OBD-2 compliant vehicles requiring comprehensive powertrain sensor scanning and code reading, we recommend our OBD2 Allinone scan tool, designed for full OBD2 system diagnostics.
This 16-pin shell cable is specifically designed for the 16-pin OBD2 style connector and is not compatible with the 12-pin style OBD1 ALDL connector commonly found in most 1984 to 1995 GM vehicles. For maximum compatibility across all years of OBD1 cars, including your 94-95 models, consider our bare pin cable. This alternative offers broader coverage for diverse OBD1 systems.
