Black = Ground
Red = Power
Green = Coil
White = Lights

Also i plan on running dual batteries to, i was going to have a battery on each wheel well in the back in a battery box.

Dual batteries need to be isolated from each other when the engine is off.
You can use one of the dual diode type, a switch, or a relay.
I use a relay on mine because I don't like the .7V drop the diodes have.

AN the stock alt is rated at 60A.
