OK! I found the data link box, but it is not look like your picture. It only has 17 pins in it. It also has a rubber pull off cover on a pin mounted outside of this box that is marked 1G -. I don't know if that is what you are talking about. Also my prizm is a 1990 1/2 model vin 6 if that matters.I want to make sure before I start sticking meters into wrong connections and short something out. Been there done that! Thanks.
