Hello new to the forum and to Harley bikes pretty much. Bought a 05 Deluxe and found the following plugs under the seat. Maybe someone can help identify what their used for? Thank you all!
Third one is a Packard style connector , could be almost anything but it probably powered whatever the antenna went to. I don't think Harley ever used these. You might find some branding somewhere on the harness if you follow it.
