It depends on the vehicle, and the electrical devices that may demand the need for a direct connection to the battery. For example, a super large sound system and/or a large audio amplifier may need guaranteed power and thus may be wired directly to the battery with its own Positive AND Negative wires connected directly to the battery.
"Extra" wires on the Positive terminal usually feed special circuits that either need to be 'Hot" all the time, even when the key is off, OR need the current that can be supplied only by its own dedicated power supply wire.
Extra wires connected to the Negative terminal "usually" serve electrical devices that require their own, solid ground connection.

Which wires are positive and negative in a 2002 vw jetta?
If you mean the battery wires look at the battery terminals the positive terminal is always the biggest diameter
What flows through wires that are hooked to a battery?
Electrons flow through wires that are hooked to a battery. The battery's negative terminal repels the electrons, while the positive terminal attracts them.
What are the rear right and rear left positive and negative speaker wire colors for a 2008 civic?
The red wire and terminal on a 2008 Honda Civic are the positive wires for the battery. The black wires and terminal is the negative battery cable.
What are the two places on a battery to which circiut wires can be attached called?
Positive and Negative Terminal.
How can you tell which is positive and which is negative on a speaker hookup?
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

Why most car bodies are attached to the negative terminal of the battery?
The DC electrical system of the car requires a positive and negative electrical conductors for each electrical device. Taking the example of a single lightbulb powered by the car battery, this could require a wire leading from the positive terminal of the battery to one terminal on the lightbulb and a second (return) wire leading from the other terminal on the lightbulb back to the negative terminal on the battery. Two wires are required - a positive and negative. To reduce the quantity of wires required, the negative "wire" is actually the car body. Hence there is a positive wire leading from the positive terminal of the battery to the positive terminal of each electrical device on the car and the negative terminal of each electrical device on the car is connected to the car body (a metal conductor). The body of the car is then connected to the negative terminal of the battery, completing the circuit. There are virtually no return wires. This works as cars use a low voltage (12 V). If they used a higher voltage, this system could result in electric shock from touching the car body.
How do you make a cheap physics working model on electric circuits?
take a battery or cell,two wires, a small bulb.connect the wires with cell,one on positive terminal and second on negative terminal and other sides of wires with the bulb.the bulb will glow
What color is positive on a car battery?
Normally red or brown. The battery has a + stamped into it by the positive terminal. Follow the wires, on a modern car the positive will go to the alternator and starter. The negative wire (easier to follow) will go to the body/engine block
What battery terminal on a 1996 low rider gets the two wires?
the positive
How do you manually raise a power window?
Run a wire from the POSITIVE terminal on the battery and touch the red wire (positive) to the window motor and run another wire from the NEGATIVE terminal on the battery and touch the green wire (negative) to the window motor. The window should go down. Reverse the wires to make the window go up.
How do you Manually raise a passenger power window?
Run a wire from the POSITIVE terminal on the battery and touch the red wire (positive) to the window motor and run another wire from the NEGATIVE terminal on the battery and touch the green wire (negative) to the window motor. The window should go down. Reverse the wires to make the window go up.
What are the two places on a battery to which battery circuit wires can be attached?
Positive and Negative Terminals.
