73 A/C Compressor hot wire?
Hey folks,
Im just about finished restoring a 73.5 CIS with a 2.7 from a 77 911. Im trying to hook up the a/c compressor and I can't find a dadgum hot wire! What color wire should I be looking for? I know it has to have 12v when the fan switch is turned to 1,2,or 3. I've searched factory manuals to no avail. Any help is appreciated. TIA -Josh |

Separate fat green wire in a sheath run through tunnel. Not in the factory through body harness.
Have to add it if it isn’t there.

Power flows from fuse #2 to the primary AC relay located in the beer cooler in the front trunk; when ign key on accessory or run position.
When evap fan speed switch is turned 'on' (1,2 or 3) power flows to the AC thermostat (from primary AC relay). When the AC thermostat contacts 'make' power flows to the AC power wire for the clutch down by the oil filter and RH rear tail light. Similar AC circuit from 1970 ish through 1989; 911,912, 930
