This ALDL cable with a 16-pin OBD2 connector and USB interface is specifically designed for connecting to General Motors (GM) vehicles from 1994 and 1995 that utilize the OBD1 system but are equipped with a 16-pin OBD2 style diagnostic connector. These vehicles, including models like the Camaro, Firebird, Corvette, and other LT1 engine equipped cars, as well as certain Australian Holden and Commodore models, feature an ECM/PCM interface accessible through this 16-pin connector under the dashboard.
The primary advantage of this Aldl Cable Obd2 is its convenience. If your 1994 or 1995 GM car has the 16-pin OBD2 style connector, this cable allows for a straightforward plug-in experience. Simply locate the connector under your car’s dash and connect the cable to interface with your vehicle’s computer system.
For detailed information and diagrams illustrating different connector styles, including OBD2 pinouts, please refer to our GM OBD1 home page. It is crucial to verify the connector type under your 1994-95 vehicle’s dashboard to ensure compatibility before ordering this cable.
Vehicles from 1994 and 1995 equipped with the 16-pin OBD2 style connector are designed with built-in power and ground circuits. Pin 16 provides a +12v power supply, while pin 5 serves as the ground. The 8192 baud serial data communication, essential for diagnostic purposes, is transmitted through pin 9 in these connectors.
Beyond standard diagnostics, this 16 pin USB ALDL cable also offers advanced capabilities, such as instrument cluster programming for specific GM models. Notably, it is compatible with the 2004, 2005, and 2006 Pontiac GTO for instrument cluster modifications. Using dedicated instrument cluster programming software, users can customize features like shift light activation based on RPM, cluster logos, and shutdown text displays. This functionality may extend to other newer GM cars and trucks, opening doors for innovative software solutions in instrument dash cluster reprogramming.
It’s important to understand that while these 1994 and 1995 vehicles use the OBD2 style connector, they operate on OBD1 ECM/PCM systems internally. Therefore, this aldl cable obd2 is designed for OBD1 communication protocols. If you own a 1996 or newer vehicle that is truly OBD2 compliant and require comprehensive powertrain sensor scanning and code reading, we recommend our OBD2 Allinone scan tool, which is specifically built for those systems.
This 16-pin shell cable is not compatible with the 12-pin style OBD1 ALDL connectors found in most 1984 to 1995 vehicles. For users seeking maximum compatibility across all years of OBD1 GM cars, including 1994 and 1995 models with both connector types, we suggest considering our bare pin cable. The bare pin cable offers versatile connectivity for a wider range of OBD1 systems.
