Transmission cooling line routing question.

Hello All,



I recently decided it would be a good idea to replace my leaking radiator myself, after lots of cuss words, broken knuckles and broken metal transmission lines, and 2 hours of my life I'll never get back.. it came out.. Now, I went ahead and bought new lines (pictured)







But, I can't for the life of me figure out which rubber hose to plug the top vs bottom in. Does it matter? Thanks!
