Sir, Maruti recalls some cars to fix faulty 'wiring harness'. I understand 'wiring harness' is not wiring itself'. Wiring harness is something that hold the wires together. If it is so, how can a wiring harness can affect the electrical system in a car? Or How a 'wiring harness' can affect the operations of a car?? What are the consequences of a faulty wiring harness?
