So after looking at this label (complete with the space) on the wiring diagram that came with my harness, it finally occurred to me that this means: "alternator exciter light". I am familiar with this and am wondering, do I need one with a "one wire alternator"?
Thanks Squirrel. I had that harness for several months before I installed it and was stumped about what the hell that label meant!
