Accordingly, what wires connect to positive battery terminal?
Place the new battery by clamping it to the mounting and replacing the cable connectors, red to the positive terminal, and black to the negative terminal. In many cars, the negative (black) cable connects to the chassis or engine frame, because it's the ground wire.
How can you tell if a cable is positive or negative?
If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive.

Current flow from positive to negative no matter whatever load you put there will be flow of current. When you touch “live” wires together, you're basically short-circuiting whatever source is driving them – and so a fairly large current flows, if only briefly (i.e., until the fuse blows or the breaker opens).
