Accumate BMW plug adaptor cable. This is for the previous version of the Accumate charger and will not work with the current Accumate charger we sell now. Allows you to plug the charger directly into the accessory plug on your bike. Will also work for a standard 12V auto (cigarette lighter plug). NOTE: on some Hexhead models you will need to use an outlet that is wired directly to the battery (bypassing the can-bus system).
