Thanks much for your help, Pepi!
Sounds like a marketing tool, must make the blower motor go out faster, constantly running, and since atleast I know the 73's, are a PIA to get out.

I want to remind you guys that I replaced the Control head with a Newer model so the Switch is a little different.....
I used the correct control head harness and it plugged right into the plug from the Engine Compartment.
Ill compare it to my 75 original harness in an hour or so when I get home and see if there are any differences.
Thanks again...
