Always hook up the red or positive cable first, otherwise you could cause a short between the battery and the car through your wrench. Ths of course could cause an explosion or other problems. The black or negative cable goes straight to the engine and the car's frame, so your wrench can touch the frame when you are tightening the cable end on the battery with no worry.
