I saved this (I think) from an eBay auction back in 2011 because I thought it was a very interesting photo of the heater control valve, original heater hose markings, and the application of the asphalt wrap on the AC expansion valve.
It is an X code 390-2V Cougar, probably San Jose because there seems to be many from there and few from Dearborn. Apologies if it has already been posted here previously, I just came across it in some old files.
