My 1 pin has voltage with the key turned off. This is on my '71 by the way which I am running an internally regulated alternator circra 3rd gen now in a one wire configuration. I don't think I should just swap the wires on the pins, I think I should find a switched power source maybe? I did a similar one wire conversion on my '74 and that works great! so sometimes I know what I'm doing, lol

This 2 pin is correct it is hot all the time.
