I am removing my ashtray and cigar lighter as I have no need for them. I am putting in a new power outlet (old cigar lighter socket with a fancy new name) and was wondering about the polarity of the connections. I assume that the center pole is + and the case is - (ground). Right?

Since the whole chassis is attached to the battery's negative terminal the "hot" wire is the + one.
Be sure the device that you'll be plugging into the power outlet expects that polarity.

That is the way it's been on every car that I've ever worked on, and that is what virtually all 12 volt accessories that use a lighter plug expect to find.
