I looked up the A/C diagram in my 1967 Plymouth service manual, and the wiring is pretty clear. Four wires go to switch. A low speed, a medium speed, and the high speed and motor wire which are connected together. The manuals can be downloaded and you can see which terminals the wires go to. The color codes of wires on also on the diagram.
As I look at question, you may be looking to wire the heater blower motor resistor. It is also on the same diagram.
