The master switch and the compressor switch is on your heat box inside the
car and is controlled by your levers.
Your diagram is hard to read (blurry). Can you scan a better one? This is
what I would do if It were me doing it. Be sure the fuse in the fuse block
is good. Install a 30 amp fuse in the line coming from the horn relay. It's
true that this supplies a full 12v to the heater but it may feed the purple
wire to your motor also. Hard to tell from your drawing. Put the plugs back
on the relay and the resistor. Take a volt meter or a rigged up 12v bulb or
test light and with the ignition in the on position see if the purple or the
orange has power. If you have a volt meter or a test light you can also
probe the sockets that plug onto the resistor or relay. At least this will
tell you if any wire has power. Let me know. If that fails I'll go to see my
buddy tomorrow and look at his '69 again. I'm doing this from memory when we
put his together.

The fan works when hooked directly to electrical power but the purple
lead is dead all the time.
I'm trying to figure out where the power is supposed to be coming from.
I'm not great at reading wiring diagrams, but it looks like there is a
14ga brown wire coming from the fuse box to the "master switch" (whatever
that is) and a 14T (tan?) wire going from that switch to the blower
switch.
This is the diagram I am using:

Can anyone confirm where I am supposed to be tracing power from?
Thanks,
