1994 Oldsmobile Ciera retrieving stored codes

Computer problem
1994 Oldsmobile Ciera 6 cyl Front Wheel Drive Automatic

my 94 olds cutlass ciera has the check engine light on, and I was wondering, to rerieve the codes on this OBDI style, to have the check engin light blink the stored codes at me, do I just turn the key on and off 5 times, or do I need to jump pins in the DLC, and which ones if so?
