Positive or Negative on Bosch coil

I am trying to install a Pertronix Ignitor in my 009 distributor and am at the point of connecting the wires.

It says to connect the red wire to positive side of coil. The coil is marked with a 1 or 19, not + or -. Any ideas?

Found the answer here. Never mind. I think it was a 15 not a 19

Eric,
You will love the ignitor. As a tip, make sure the wires are routed as far from the shaft as possible. I secured mine with a nylon tie on both sides so it wouldn't move. I think a friend of Jerry's had one rub the insulation off and short out. You don't want that to happen. Nuff said?
