So an ignition has two posts, one hooks up to 12v+, what does the other post hook up to?

My dist has two wires coming from it, one red, one black. The red is 12v+, and the black wire goes to the other post on the coil. I would think it was 12v-, but then by process of elimination there is no wire left for the tach signal... Is it the tach signal?
