Hoping someone can help me here. The CEL on my 2000 Forester keeps going on and off at random times. I think it's probably the rear O2 sensor. I purchased a OBD-II scanner/reader to check it out, but I'm having a hard time seeing where to plug it in under the dash (it's probably staring me in the face, but I just don't recongnize it). Can anyone here give me a good description of where I can find it, exactly what it looks like (color, etc), and so on, so I can find it? A quick photo would be great as well! Thanks to everyone and anyone who has the time to help!
