Then connect the negative post of the first battery to the negative post of the second battery. Now connect the positive post of the first battery to the positive connection on the vehicle. Then connect the negative post of the first battery to the negative cable of the vehicle. Click the link for a diagram.

There are typically two cables, one is usually red and the other black. The black cable attaches to the negative terminal on the battery and the red wire connects to the positive terminal on the battery. When removing the battery from the vehicle always remove the negative cable from the battery first. When installing the new battery always connect the negative cable to the battery last.
Nothing happens to the vehicle if you connect the negative side first.But is is safer to connect the positive side first. Reason If the negative side is already connected and you put the positive side on you take a chance of touching a part of the body or radiator with your wrench while tightening it, causing the positive side to ground out. If your negative side is not connected yet and you touch the wrench to the body while tighting the positive side nothing will happen. So installing the positive side first reduces the chance of shorting the battery out which could cause the battery to explode.
