TECH. NOTES: 
 
 What is General Motors' C.A.C. A/C? 
 
 Cars of this era were either manufactured with: 
 
 - C.A.C. 
 C.A.C. stood for "Cool Air Comfort" fresh air ventilation only. This ventilation system used a manually-operated slider cable to open/close a ventilation door near the floorboard. There is no wiring involved with C.A.C. only cars. C.A.C. could either be ordered separately without air-conditioning, or it came automatically installed on all factory-installed A/C cars of that era.) 
 
 - C.A.C. A/C. 
 This meant C.A.C. + optional factory installed "Basic" air-conditioning. "Basic" air-conditioning meant that it was not a user-settable temperature / climate controlled air-conditioning like the trade named Comfortron or Circ-L-Aire (for example). 
 
 - COMFORTRON, CIRC-L-AIRE, or other user-settable temperature / climate control A/C systems. 
 These were factory installed air-conditioning systems, only installed on fullsize cars, and were a RARE factory option. 
 
 - COOL PACK A/C. 
 This was an optional under dash air-conditioning unit, usually dealer installed. Lectric Limited does not manufacture the wiring for the Cool Pack A/C system itself. However, if you have the Cool Pack A/C system, you can buy the Lectric Limited wiring for a non-A/C car, and re-use your original wiring from the dealer-installed Cool Pack A/C.
