Thanks Rick,
That link didn't work for me. I have to stop because it's getting dark.
There is also an orange wire coming off the harness that has a little
boot on it. I thought it was supposed to go to the blower motor but it
seems like there's already a wire there (on the motor). There is a
ground lug there and I hooked it up. The purple wire is also back in
the connector where it's supposed to be, and should be making contact.
As of now the new heater core & blower motor are both in but the
blower is not working. I replaced the fuse and tried it on all speeds,
with and without the hot lead from the horn relay touching the other
wire it's supposed to connect to. So far no luck. I put the fender on
w/ just a couple of bolts because I'm assuming there's a good chance
I'll be taking it off again tomorrow.
Still need to know what the orange wire from the harness is for and
need to figure out why the blower is not working.

Quoting Rick Schaefer <[EMAIL PROTECTED]>:
John the wire coming directly from the horn relay, thru the fuse holder
& relay only controls the hi speed of the blower. The lower 3 speeds go
thru the heater box resistor. Also, if your heater box (where the fan
mounts) is fiberglass (like mine) you need the dedicated ground wire. On
mine it goes from one of the motor mount screws to the body. Without the
ground wire it won't work on any speed - ask me how I know that one.
This wiring diagram may help you :
http://elcaminocentral.com/articles/wiring/712.gif It does not show the
A/C high speed wiring but the wiring thru the resistor is there. You can
expand the image by running your cursor over the diagram & then clicking on
the orange icon that will appear in the lower right. Gives you standard
wiring color codes for a 69.

Thanks. That helps a lot because for all I know the blower motor that
is in there might work, which would mean that all I really need to
replace is the heater core. I'll see what it takes to get that purple
wire back where it belongs and test the other one like you said.
BTW, in mine the long wire w/ the female fuse holder on it is black
and the short one w/ the male end on it is orange.
