GM Historic
Prior to1996, most GM vehicles used the 12-pin Assembly Line
Diagnostic Link (ALDL) DLC. The GM ALDL cable kit includes the ALDL
adapter and cigarette lighter power cable. This adapter cable is
included with the Scan Tool. In 1994 and 1995, certain GM vehicles
used the J1962 (OBD II) DLC, but are not OBD II compliant. Refer to
Appendix B - Data Link Connectors.
Use the cigarette lighter cable to provide 12V to the
tool.
The ALDL DLCs are usually located
under the dashboard on the driver’s
side.
On Corvettes and Fieros, the DLC may
be located in the center console behind
the ashtray. Refer to service manual
for exact location. It may be in full view,
or it may be recessed behind a panel. An opening in the panel should
allow access to the recessed connector.
