I have 69 plymouth that has been converted over to electronic ignition. Im getting a weak spark and the car isnt starting. I went to autozone and they have different part numbers for different years, Kragen has a similar spark control module but it only has 4 poles and not 5. the part number it has on it is 0258A14 but autozone doesnt have a cross reference for that number. Any ideas what module it needs? they tested it as if was a 74 and he said it failed...
