Before the final layer of heat shrink, I cut off the plus and minus molded onto the sides of the plug with a razor blade. They were labeled wrong anyway for my application. Now heat the big outer piece of heat shrink.

Success!!! Now I can sit in my favorite lazy boy chair, without trying to break the power connector on the arm of the chair.
