I thought with the many questions I see on this forum about codes I would submit thirty years of info that I have scribbled down in a few books, junkyard research, Old magazines, etc. I kept during restorations over the years. This list is huge and covers codes from 1969 to around 1983. I will add to this list as time permits and if anybody notices any codes that may or are incorrect please feel free to challenge. a lot of this is hand written and is subject to mistakes. If this lists help one person it will be worth the time to input this data. I realized most of this info is available with on line decoders, but a list might be helpful to some. Next post will be "F" codes.
If this info is unneeded and the collective thinks this is unnecessary, please let me know. It will save a lot of two finger typing..lol. This list is by no means complete, but cover the most common codes, and a few obscure.
