Maybe all of the people should replace the wiring harnesses in the DC-3's they're flying as those harnesses are over 80 years old for the most part.
I guess I should have been more clear, Ken. After 37 years of unknowns you''re calling out the factory for poor QA/QC procedures. My point is that if you're that concerned you should probably just replace the harness with a third party unit and get some peace of mind. Who knows when someone probed that insulation with a test light probe, or even with a needle or sewing pin into the conductors trying to verify current flow to the back of the car. It's a good catch, and I'm sure it caused significant frustration to find that small section with the flaw, but I cannot see blaming the OEM for something after this much time. You did a great job, but calling the factory out for poor performance is hard to justify in my mind. You found it, you fixed it, and it's not GM's fault, IMO.
