OTC OBD I & II Scan Tool 3211
Making a Connection
Here are the OBD II tool and car connections side by side. As you can see not all pins are used in the Cobalt's connector. Before installing the cable, I carefully checked to be sure the car's connector was clean. Maybe it's just me, but it seems like this would be a prime candidate for a cover of some kind — even if it is inside the cabin, unlike the Ford EEC IV connectors.
