The older GM cars used CCC (Computer Command Control) as the engine computer. Check the engine emissions sticker or the manufacturer's documentation first, but the general procedure to set the timing is to 1.) disconnect the 4 wire connector at the distributor, 2.) verify idle RPM, 3.) set timing with a light per the spec, 4.) reconnect the distributor, and 5.) reset the fault code caused by disconnecting the distributor.
