Mine has a Hella (DIN) plug on it that fits both a standard car cigarette lighter socket and the smaller diameter Hella BMW bike power socket.
The pump draws more than 5 amps so will trip the socket on a BMW motorcycle, you need to fit a separate socket fused directly to the battery.
The bonus is, once fitted you can also use the socket to optimate the battery directly (without all that canbus power management bollocks).
