There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.

Where is the positive battery terminal?

The positive terminal is colored red and will be connected to the plus side of the battery. The plus sign will be stamped into the plastic battery casing, it may be difficult to spot at first, but it is there.

Which terminal should I connect first?

“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
