Reply to Need to hook up a Hercules controller to my S4? Help?

Ok usually what I would do for plugging in any controller to my S4 is just hooking up their main out to my channel C or D by a rca cable obviously. BUT, if you look at the third or fourth picture, it shows the back. Notice how there are multiple main outs? Which one do I plug the rca's into so that it hooks up to my S4? Stuck here homies.
