[TR] Coil and spark plugs polarity

[Greg Lemon]

No to number one, yes to number two, at least according to this article as I 
read it, and reversing the coil wires when you switch polarity is how you 
keep it that way.

The car will generally run fine wired either way, but if something else is 
marginal or a stronger spark is needed you get a better spark if it is wired 
to have the center electrode negative.
