this is a partial wiring diagram for an Lm339 quad comparator. Where do the lines with the questionmarks go when u look at the pin diagram for the comparator. It's a 14 pin comparator. Diagram says 5 lines to the comparator, 3 of which I can tell. That leaves11 pins 2 choose from. where do the 2 wires go and why don't they just tell u or label them?
