The center electrode will be the opposite of the ground that you're
using. Negative ground = positive center electrode, Positive ground
= negative center electrode. Has to be that way to produce a spark -
otherwise there's no current flow. I believe that the coil has a +
and - connector but need to go look again to be sure.
