Topic: How Many Wires & What Color, Please?

[MWM]

On a 1965 San Jose with A/C, how many wires are on the heater motor and what color?  Approximately when did the heater motor change from three wires to two wires with the resistor?
Thanks!

The change was around March/April of '65.  The earlier cars had orange/red and black heater motor wires.  Later were brown and yellow.  The front of the heater box on the early cars had no hole for the resistor.  Thus, the main wiring harness is different between the two also.
