The lift has a 4 wire flat plug that is for the tag light bracket for the bulb. The vehicle does not power the lift. The lift is powered by plugging the power cord of the lift into the charging port of a Hoveround MPV5 chair. The lift may also be raised and lowered with a socket wrench, when you remove the plug at the top of the lift. The bottom plate of the lift folds up, and there is a belt to secure the chair for transport.
The lift has the optional swing away arm (see the red knob). This will allow you to swing the empty lift out of the way to access the trunk or gate. The lift is not designed to have the chair on the lift to swing it out of the way.
