The negative terminal of the battery is black and marked with a negative, or minus ( - ) sign. It is the grounding system of the car, and everything loops back to it either through the steel chassis (which has a big fat wire tied to the negative side of the battery), else green or black w/white stripe wires so the electricity can flow in and out of the battery and through all the electrical stuff.
The positive ( + ) terminal is red, as are most of the 12v wires powering each little component.
To ground something to the negative terminal, you can generally crimp a little ring on the end of the ground wire and stick it under ANY nearby screw that goes into the steel chassis. Make sure there is no paint or corrosion under the ring and it is snug, so the screw doesn't vibrate loose.
If you hook up stuff backwards, it will not work, or it can 'short' (cross-up) the circuit and fry it. Careful attention must be paid to what was there (take pictures as you take stuff apart to replace something) and the wiring diagrams. Label wires with a piece of tape and a fine-point Sharpie as you work.
They are the side of the battery used for ground, it is grounded to the body of the car thus alternating the positive you provide from the other side. Batterys are also ac via alternator and dc with a relay to control voltage and prevent draining of the battery

Positive and Negative Terminals.
There are 2 battery terminals. A positive or hot and a negative or ground. The positive is slightly larger than the negative.
The positive terminal of a battery is where electrons flow out, while the negative terminal is where electrons flow in.
Remove the negative cable first and when installing the new battery connect the negative last.
On any car, switching the battery hookups will most likely fry your battery.
