    Awesome... thanks so much!

      Since I can't start new thread in here I will post here on this one.
      Anyone know the pin out voltages of the OBC plug? Not the coding plug but the input plug from the instrument cluster (green color)

      I get voltages on the lines I need but it varies and my range function, ave MPG & ave MPH are not working.

        I haven't seen one OBC post about the text being garbled and running like wet ink. My obc bugs me every time I turn the car on. What am I missing. Sometimes the numbers are perfect and clear and other times, just garbled. It could be a poor connection somewhere as a bump on the side of the glove box area will fix it temporarily.

          they are known to do that, probably loose conection.
