Without any pictures I'm responding based on how I did mine: my 1-wire alternator goes straight to the positive post on my 12v starter. There is also a "jumper" wire going from the single alternator post to the two tang (right is the correct tang) "B" terminal on the alternator (mine is a GM alternator, but follow me) which is the "exciter" or "step up" wire. Without this the alternator voltage will not "kick up" enough to charge your batteries.
Hope this helps,
Gary
