You are looking for an assembled connection that has the male and female connectors plugged together; you'll need to separate them to install the harness with the ipod module.
The connectors are six-wire connectors, black in color. They probably have only four wires in them: black/green; red/orange; blue/yellow; and, violet/gray colors.
The connectors will be close to the radio side or bottom, depending on how the larger harness was arranged. What you are looking for is there.
Suggestion: If you don't have one already, buy the HD Service Manual supplement for your bike; it has wiring diagrams identifying the multitude of electrical connections, wire colors, and locations.
Good luck with your search.
