These wires send power and signals from the car’s battery to everything that needs it—like the engine, lights, music player, air conditioning, etc. If these wires were not there or were messy, none of those parts would work. A wire harness keeps all the cables safe and stops them from touching each other, melting from heat, or breaking. This makes the car work better, last longer, and look cleaner.
