Obviously the positive one....which is best found by being the one that DOESN'T end at a ground point. the easiest solution to that is to start from the starter. the LARGEST (presumibly black) wire from the starter to the battery terminal is the GROUND. that would make the other terminal the positive.
Red, positive + cable to Positive + battery terminal. Black, negative - cable to Negative - battery terminal.
The battery post positive terminal is where you connect the positive cable. Connect the negative cable to anyplace on the engine or chassis. Connect positive first and remove it last.
From battery to starter solenoid
It is usually red.
There is no way that the positive battery terminal was ever connected to the chassis. This would be a dead short and would fry the battery. Negative to chassis is correct, but positive to chassis, no way. That positive cable goes somewhere else.
When connected to the cable which normally runs to the starter it completes the circuit. Electrons flow from the negative terminal to the positive terminal.
its the red one conected to the positive terminal
Getting a factory terminal is likely not worth it. First make sure the battery cable has enough slack to cut off the terminal, shave back the insulation and use a new terminal. If you don't have enough slack, you'll need to replace the entire cable. If you have enough, remove the battery to save yourself from accidentally grounding/shorting our the battery. Remove the negative battery cable, then remove the positive. Remove the battery. Cut the battery cable where the terminal is. Strip about an inch of insulation. For my 2003 TL, I had to use the truck size terminal from Autozone as the normal one would not fit the 2 battery cables. Truck size = $3.50, car size = $2.99, not a big difference. Make sure the cable is free of corrosion. If there is any of the powder blue dust, clean it all out with a wire brush. Get the battery cable into the new terminal and tighten. Use electrical tape to cover any excess uncovered battery cable. Pop the battery back in, install the positive terminal then the negative terminal.
In most properly wired cars, a red cable goes to the positive terminal on the battery, and a black cable goes to the negative terminal. If color coding doesn't work, negative is the ground cable, positive is where your power is going.
A battery terminal or a battery CABLE terminal. If the terminal is gone or destroyed on the battery, you need a new battery. If the cable terminal is terminal, you can buy an after market replacement or a complete new cable with terminal at most any auto parts store.

REMOVAL Turn the ignition switch to the Off position. Be certain that all electrical accessories are turned off. Loosen the battery negative cable terminal clamp pinch-bolt hex nut. Disconnect the battery negative cable terminal clamp from the battery negative terminal post. If necessary, use a battery terminal puller (2) to remove the terminal clamp from the battery post. Loosen the battery positive cable terminal clamp pinch-bolt hex nut. Disconnect the battery positive cable terminal clamp from the battery positive terminal post. If necessary, use a battery terminal puller (2) to remove the terminal clamp from the battery post. Remove the battery cables from the battery. Remove the battery thermal guard (1). Remove the battery hold down bolt (1) and battery hold down (2) from the battery. WARNING: Wear a suitable pair of rubber gloves (not the household type) when removing a battery by hand. Safety glasses should also be worn. If the battery is cracked or leaking, the electrolyte can burn the skin and eyes. Remove the battery from the battery tray.
