I have the powerlet female plug that is plug and play to a connection under the tank which even has a hole cut into our frames to hold into place. Do a search on powerlet in the accessories section.
Then also buy the powerlet male connector and because most 12v wiring consists of only a positive and negative wires, cut off the existing wire end from your tender leads and connect them to the male connector. Powerlet sends a diagram which shows where the positive and negative connections attach. Then simply plug into your bike's new female powerlet fixture and turn on the charger and you'll be charging your battery.
