I broke the end of the plug on a 12v air pump that I carry in case my
Vanagon picks up a nail and  a slow leak.   I got a replacement from
Radio Shack that has spring loaded wholes for the + and - wires.  From
looking at the insides of the broken plug which has a short red wire
inside, it appears that the positive wire goes to the center prong of
the plug and the negative wire to the side contacts.

Is this correct?

Hopefully I won't do this, but what would be the consequence for the
pump if I accidentally wired it backwards?
