This cable will work with any OBD1 system, but requires you to plug the bare male pin from the ALDL cable into the correct female pin location on the cars OBDI connector. The female pin location can vary with the style of connector and year of car. See our GM OBD1 home page for references and diagrams of the connectors styles.The bare OBD2 pin is a slightly smaller pin physically than the OBD1 pin. See our Kits page for a size comparison. The OBD2 pin will fit into any OBD1 connector, either upside down or right side up, but is not quite as tight a fit when right side up. We have seen connector pin locations that are well used on the 12 pin OBD1 cars where the OBD2 pin is a little loose when plugged in right side up. Not a big issue, but we should mention it.
