what line go's where?

Did you bleed the M/C first? If the compensating port in the M/C saw air, the M/C will need to be bench bled.
If the rear system has air in it, the peddle will go nearly to the floor.This is normal.
If the rear brakes are way out of adjustment, then it will take several pumps to push enough fluid back there to push the W/Cs out far enough to energize the shoes. When the shoes finally get out far enough to do their job, then the pedal comes up and gets hard.Did you adjust the rear brake star-adjusters?
If the pushrod adjustment is too short the peddle will start from a handicap.
To prove the problem is in the rear, simply clamp the rear RUBBER flex hose. Do not clamp braided anything. The pedal should be hard, cuz now you are energizing only the front.If it doesn't get hard, you will have to fix the front first.
