Wire choice: so I am using AWG wire. Mostly because it’s about 10% bigger than SAE and that is what I have , so that is what i’m going to use. The list below is for AGM wire you can reduce by 10% for SAE . Now the only thing I really know about electricity is there is smoke running through the wire and in to something (like your fuse box or light) and back out to the ground . The key to thing Remember when doing wiring is you don’t want to let the smoke out, bad things happen when the smoke gets out. You know like fire.

Wire for Lights
From the February, 2009 issue of Jp

For the Main power I am using 2 gage wire in to the battery separator( recommended size from the battery separator company) I am using an Anderson power connector to plug in to the vehicle.

The separator is what is what enables me to use different batters if you don’t use a separator your battery’s need to be the same and same age. For my purpose I want to move this from vehicle to vehicle or stand alone, and the separator is what allows us to do that.

For the fuse box positive and ground 6 gage wire. The fuse box feed 5 relays 4 are for power outlets 2 50amp Anderson connectors , 2 are for 12v out lets (lighter outlets) and one go’s to the battery separator’s override.

There is 2 gage wire that go to a 175 amp Anderson power connector for things like jumper cables,wench or other high draw appliances.

The wire harnesses for the relays have 16 gage wire I run that in to a cat5 outlet so I can put a remote switch box in the front of the vehicle.
