Where is the data port

Under the driver's side of the dash close to your knee if sitting in the car. easy to find.shaped like a BIG letter D,but turned sideways.

I have a 2006 Sebring Convertible. My data port is located under the dash near the steering wheel. It will be a bunch a wires connected to a square tip which is the plug that goes into the tester. I bought a tester at Harbor Freight (about $60). You connect the tester to the plug (car off) and then turn on the car. The tester read the possible code problems then.
