Heater issues....

[ABX131]

The deluxe heater in our 63 does not work. My son has been bugging me to fix it because it is cold out when he goes to school. In his defense it has been about 30 deg on average here lately and he should have a defroster. Here is the issue. The PO gutted the whole wiring harness and I have no wiring at all. It appears the hardware is all there. The ducting, fan motor and controls and cables. All the control handles are broken off including the fan switch. The motor has no wires or plugs on it and has a 1 inch hole is the side of it. Question it what specifically am I missing? I went a junk yard yesterday but most of their stuff was already gutted? I looked at a 73-85 generation and it looks like the fan motor is the same but I am not sure if I could use the wiring from it or how it wires up. Need more info before I act upon this.
