thanks for the simplified drawing Trailbeast , I was hoping to do this hidden in an old chrome box for looks. I called about the "new" Flamethrower 3 HEI module but the folks at Pertronix told me it was in pre-production with a release date of 2/16 , didn't bother asking if that's Feb 16 of this year or Feb 2016 , I was too discouraged to bother .Hate it when companies show new products and list them on supplier sites like Summit before they actually exist .
