Not an expert here --- my installation would be + to switch/battery in a 
negatively grounded system.  Positively grounded system I'd go with + 
wire to distributor.

You can find an article on this at;

I can't vouch for the article's accuracy but it does give some useful 
info and also how to check the spark polarity if you want to do so.
