You gave me the exact help I needed and I’m very thankful. My car was factory ac too. Classic Industries sells these harnesses on Ebay. But, the picture they provide of the harness is rolled up in a circle and you can’t decipher what’s included or not. Like you said. It’s better to buy a new harness compared to used. But, if I can save $25 on an already expensive new harness. That’s what I ll go for. $125 is definitely worth while. Classic Industries and Year One are always over priced. I understand the high cost on some items. I can’t handle the sales gimmicks and lies. I try to avoid that company as much as possible.
