OTC OBD I & II Scan Tool 3211

Everything I Needed

In order to check out the hissy fit the Cobalt SS/SC was having, I needed to use these three components: the Scan Tool, the Extension/Adapter Cable, and the OBD II Cable. I didn't need the Cigarette Lighter Power Cable because — as mentioned above — the OBD II connector is self-powered and is used to power the tool. Like with the screw on the back of the tool, be careful with the screws in the cables. Don't over tighten, but do press the cables firmly together before turning the screws down, it will keep the cable from getting cocked, which can cause you to cross-thread the screws.
