Altec model 19 crossover wire connections?

Options
Hello, I have a pair of model 19 crossovers, but all the connecting wires were removed. I know which wires go to which posts but I don't know which black wires go with which colored wires (Green, White, Red). There are two rows of 10 solder posts. The end (outermost) row has black wires at post 4 and 7 counting left to right. The middle (inner) row has one black wire on post 4 counting left to right. Green is LF driver +, White is input + and Red is HF +.
