Hey, look at that… found the missing wiring. The wiring was broken/cut and the connector had been pulled back out of the door into the body of the car in front of the firewall hiding within lots of other wiring. No idea why that got messed with but cough cough possibly from an accident repair a long time ago? Either way, I’ll get this patched back in and hopefully that fixes things and there aren’t other issues. I’ll report back!
