There is a slight difference when it come to its wiring system. I don't know about the types of materials being used in hybrid cars but I'm looking for it right now. What major difference it has is the use, petroleum-driven cars uses these electrical systems mainly in starting, lighting and battery charging, but the hybrid car battery emits its power to drive the electric motor thus have the backward motion of power as the common car does.
What's important is hybrid car electrical wirings should be checked regularly. Conventional cars run without electrical wirings sometimes.
