Another noob with a wiring ?

My controller has one positive and one negative wire to connect to the batery packs. My stock controller has 2 of each . (one set per pack - 2 packs)

It seems that I need to connect two leads to the single lead on my new controller so I can connect like stock. Am I correct? If yes, what is the best way to do it?

I am only asking because some of the diagrams I have seen on this forum look funky to me.

Thanks!
