The head unit is out of a 2000 Grand Prix with digital HVAC controls. All of the parts for my build was taken from the local Pull-A-Part yard in Lafayette. Parts include; Digital head unit, connector for the head unit, temp sensors, control motors, relay block, etc.
There is a write up on the build here on the forum but for the life of me I cannot locate it.
