If you lay the harness on a large floor, most of the design will be obvious. The later harnesses (J-H #97764; first were #90587, then after chassis # 13350 were 97049, then #97764) have the nickel chrome(white with slate stripe) as opposed to the white with pink stripe) wire going from the tach to the coil, so be sure to test the reistance(!.5 ohms). If your car has a ballast resistor, then obviously you have one of the earlier harness(very little differences between the first two).
