wiring 2 batteries 2 alts together... help

[BigYellowBlur78]

I have a 2002 Silverado 1500, I already have a 270 amp alt and an Optima Yellow Top up front. I have also done the Big 3...I bought a DC Dual Alt bracket, and plan on putting my stock alt on that, and have a 2nd Optima Yellow Top in the bed of my truck. Now how would I wire those together? Would I keep the setup I have now, then run one 0 gauge wire to the back battery from the 2nd alt, one 0 gauge from the front positive battery to the back and one 0 gauge from the front negative to the back one, then ground the back battery somewhere in the bed?

very simple, just run everything in parallel.
