John, I'll attempt to answer your wiring problem.
The fuse holder is hot from the horn relay,(should be red)
it takes a 30 amp fuse. The male end should be blk/or. this should be
connected to a 3 pronged plug for your a/c relay. The purple wire should
come off this 3 pronged plug and connect to the male plug on the blower
motor. The relay plug should also have a dark blue wire that goes to another
3 prong plug for your resistor. The resistor is connected to your switch in
the car and it controls the speed of the blower motor. They all have to be
connected for the blower to work. You can check your blower by running a
wire from the bat to the male plug and see if it runs. The motor has to be
grounded so be sure you have a ground from the screw that holds the motor in
place to the body. Hope this helps you out.

While I'm mucking around under the hood...
Normally there is a hot lead going from either the battery or the horn
relay or something w/ a female fuse holder on it, going to a male fuse
holder plugged into a relay on the heat/AC box inside the engine
compartment.
This has never been hooked up since I have had my '69, but what is it
supposed to do?
There is also a purple wire that goes from the far right side of the
heat/AC box to the area of this same relay on the left side of the
box, and that is just hanging there not hooked up.
The reason I ask is b/c if either of these wires have anything to do
w/ the blower motor I should get it/them hooked up again. If they are
something to do strictly w/ the A/C, mine doesn't work anyway. The
male fuse holder is missing for some reason, but the wire is there.
How many amps is the fuse in there supposed to be? The purple wire has
a female spade connector on it but at quick glance I did not see what
it's supposed to hook up to.
Thanks,
John Nasta
