Unfortunately ford made a stack of different harnesses for the 70 so to find the correct info is difficult. IIRC the compressor wire is a green wire with a bullet connector that comes out the firewall a couple of inches.

Sorry mate, I don't have a backup that has these files in it, so I'd say they have been missing for ages and I just haven't realised.
I can't remember who sent them to me in the first place.

Bright green wires for AC, the rest is just the standard heater fan wiring the circuit is pretty standard from 67, just the main switch, thermostat and compressor in series. You'll want to add a hi/lo switch though on the drier.
