If you have a 94 or 95 car with the 16 pin connector, we sell 16 pin USB ALDL connector cables for it here. Even though it is an OBD2 connector, it has an OBD1 system behind it on these 94-95 cars. Some 1994-95 cars have the 16 pin OBD2 connector (shown below), Corvette's, Camaro's, and LT1 cars among them, as well as newer Australian Holden and Commodore. There are other styles of connectors, but the 12 pin OBD1 connector shown above is the most common. Under your cars dash you will most likely see this style connector: You can make your own cable, but it is much quicker and less headache to buy one already assembled and tested. It may possibly be the only thing you will need to buy to do your own diagnostics. Let's look at the ALDL (Assembly Line Diagnostic Link) OBD1 interface cable first, since we sell low cost ALDL OBD1 interface cables.
