Hi, I own a '67 firebird 400 with factory a/c, I was allways missing the outer assembly, however I purchased one from a '68, I need some help with wiring the thing into the car, most of the questions concern what is the connector on the blower side of the suitcase assembly. (on the top-block side is the blower motor resistor and relay) however, on the blower side of the suitcase is a 2 prong plug that isn't listed in the 67 shop supplement diagram, any info on either year or both would be more than helpful as I'm totally in the dark on the firewall forward parts that go with it, thanks, Dave
