Having seen a couple of questions regarding the built in plug on the bottom of the handles on coffeecan hoovers, here s some picture of mine apart for rewire. The first shows the pin that has to be removed to extract the plug. Pic two shows the plug removed, and the bag tensioner assembly removed. Pic three shows the hook that the spring for the bag tensioner hangs on. And, picture four shows the backside of the plug where the connections are made. The center pin is the neutral, as it is in most cases.
