However if the negative was already connected to the battery and I shorted the positive to the body with the spanner, there would now be a short circuit with a big spark and a possible fire. For the same reason I would disconnect the negative connector first too. For technical functioning it does not matter in which order you connect them.
How do you change the battery cable on a car?
Run the new positive cable back through the engine bay in the same way the old one was. Attach the negative cable to the body or block. Locate the hole the old negative cable was attached to and use the same bolt to connect the new cable.

If your battery is in the trunk, the positive cable will attach to another connector near the body of the car. Simply disconnect it from there. Remove the battery. Some cars will not require the removal of the battery while replacing battery cables, but even if it is not necessary, it may make the process easier.
Think of these cables as the large rivers that carry the water from the reservoir into a city’s water main system. The negative cable is normally black, and the positive cable is normally red. The positive cable, normally red, divides into two very large sections.
