If ya can stick your head under the middle of the dash to see the back of the heater blower motor switch, you will notice three wires connected to the back of the switch with push-on-terminals. The power wire is the one in the middle and it is a short piece of wire with the inline fuse just a few inches back from the terminal. This wire is separate from the main wire harness, as it was an "accessory" wire. It was only included in cars that had the heater.
The other two wires are the orange and red wires for "Hi" and "Low" motor speeds and they are also separate and not included in the main wire harness. These two wires were also an accessory which came taped together with some small pieces of old style sticky cloth electrical tape.
In some cases, when a southern car migrated to a colder climate and the car owner wanted a heater installed, the Ford dealer would order the "accessory" wires and install a heater at the dealership.
Now here's something I bet you didn't know. When the dealer was called upon to install a heater in a car, they would often order a F100 pickup truck recirculating air heater and install it in the car rather than install all those intricate components of the "Magic-Aire" heater. It was cheaper and less time consuming to install.

I found a photo that shows what the internal connections look like. This junction block was mounted to the left front inner fender near the back side of the headlight.

Jim,
These are the power window circuit breakers. The two on the kick panel are actually are on the ground circuit. The two in the center of the firewall are for the front windows. Crown 011.jpg
