Looking for compatible year hvac harness information for 91 Formula
So I was told the connectors have changed over the years somewhere around 86-87 and possibly other times. I need a new hvac harness for the under hood accessories and to what ever that harness hooks up to inside (control unit etc).
Some may have seen my wtb post for the engine harness and hvac harness thanks to a squirrel so I need to find out specifically what years are the same as our 91 Formy.

Yup, That's the pic I needed to see !
The HVAC-to-Engine harness plug changed many times, ( there was at least 3-4 different pre-86 connectors too,.... ) but the 87 + cars used a coolant diverter which required an additional vacuum line. The extra vacuum line simply makes it easy to distinguish the 87 & up harnesses from the pre 86 types.
