A repinning of the new connector this weekend to mirror the old one and we'll see if that does the trick. I just love electrical problems - I live for this!

wow....I never thought of that one. My 92 CHP harness was replaced also as it had been hacked by Ricky Racer so I replaced it as well. I bet it had the same issue. Let us know if you get this one solved so I can print this thread for my tech manual.....
