Cleanerman - I should have added a few more things...first, great little scooter, I've had mine for almost 3 years...and I also own a motorcycle and ride the bike probably 90% of the time but when I do ride the scooter I remember why I love it...so comfortable and easy to ride.
To get to the plug you will need to remove the seat and bucket, that's easy 5 bolts and unplug the lighter socket..then you need to also remove the luggage rack, rear fender, and battery cover. remove 1 screw from the plastics on each side under the pass footpegs and then you're free to ''unsnap' the tub from the floor plastic...3 tabs on each side right around the pass footpegs? The tutorial I linked to does a good job showing this with pictures.
First time you do it will take a while...subsequent times will all go much faster.
