Hey New Braunfels,
Used to live in San Antonio up until 2001. Have good friends in that area. Mostly motorcycle (HD) folks.
Names withheld upon request.
I miss the area a lot but.......
Anyway, What year is yours, There were 2 and 3 wire connectors made for different years. You obviously have a two connector setup. It's highly unlikely that a third wire is hiding on you. The charging system would not work properly if one wire were disconnected.
