71 roadrunner, electronic ignition. May 71 build, so not sure whether.it was converted, or if original? Carging system failed, checked out, dead alternator, sent out to be repaired. In the meantime, discovered that my engine harness was very sketchy.... degraded connection insulators, cracking wire sheathing, etc., bought a new engine harness from Megaparts. Old harness is four post ballast resistor, new harness is for two post. I've seen several cars using one side of the two sided BR, so I ran it that way. It has now killed two ECUs within a few minutes of running...... does switching to a two post BR solve this problem, or do I need to modify this harness to the prior configuration??.....it was running fine before the harness swap, however, I did have the alternator repaired too, so I broke the "one thing at a time" rule. I do still have the old harness, and it isn't butchered up, just very weathered...... any help is appreciated!!
