diagnostic port?? You're basically talking about the harness to pull the cel codes right?

Its right beneath the center console... Look behind where your head unit would be and you'll see a small blue 2 pin harness. From there, all you basically need to do is jump it - birdge a paper clip in the 2 ports on the harness. And after that, just look at the cel... one long blink = 10... short blink = 1...

so 2 long blinks + 3 short ones = a cel 23.

And after all that, if you don't want to scurry around through helms, there is a section in the FAQ here where someone listed all the cel codes already.

so when doing this is there any need to get the car computer scanned??
I mean by putting a jumper in the blue plug you will no longer need to scan the car. BTW what is the gray jumper for??? it right next to the blue one..

43 = fuel supply system.
