What all does the big 3 consist of?

As for all the above...whiskey tango foxtrot.

The "big three" is an upgrade of three wires in the vehicle's electrical system.

--The wire from the alternator output to the battery's positive terminal

--The wire from the battery's negative terminal to the vehicle chassis

--The wire from the engine block to the vehicle chassis.

I don't have information about the specific wires on a Dodge Ram, but now that you know what to look for they should be fairly easy to find. Typically you'd want to add your own wires and leave the factory wires in place, as opposed to replacing the factory wiring entirely. You may need to replace the stock battery terminals with new ones capable of connecting additional wires.

You may be able to get more specific wiring information at http://www.the12volt.com/ .

the big 3 used to be ford, gm, and chrysler. now there is only the big 2, as chrysler is no longer an american car company (the are owned by daimler benz).
