Topic: 1979 AC relay 12 volt supply/ feed info

Where does the big red wire that feeds the AC relay originate, mine has a plug on the end of it and is run toward the altenater area, but not plugged into anything and I see no female feed plug, Chilton manual schematic just states 30 amp supply. Thanks for any help. Mark

Originally it is connected to a wire with a female end that comes off the battery post on the alternator. So you can just connect it to the battery post on the alternator.
