MODERN A.C. in an OLD ALFA (Part 2)

In the last photo of Part 1 you see the dash area ready to accept the Evaporator. HA!! To get to this point took MONTHS of spare time work. An installation like this is doable, but not for the timid! A few things to note in that photo: the 4 hoses (two heater and two A.C.) hanging down on the passenger side; a white, horizontal plastic pipe above them - that's the 1-1/2" (Home Depot drain pipe) tube that will supply the end vents with cold air (the end of the left one barely visible behind all the wiring); a condensation drain tube in the driveshaft tunnel. Speaking of wiring - in my case the only Alfa Romeo wiring that will be reused are the harnesses and wires going to the dash gauges and lights. The VINTAGE AIR units are powered by just two hot leads: one from the "ignition on" of the ignition switch, and one main power from the battery + that runs through a V-A circuit breaker.

The air from the evaporator runs through 2" and 2-1/2" hoses (that come with the GEN II Evaporator) to the defroster vents and to the new center console vents. Before going to the engine compartment I am attaching the under-dash photo again now. The, on to the engine compartment in Part 3.
