Makes no sense thinking about it… Exposed to the elements… Is it really that hard to cover up some fat wires? Could be aesthetic of done properly.
In: Engineering
Much of a car’s wiring is either under the hood or inside the front dash. The only wiring that goes beyond those two points would be for tail lights, speakers, your cab light, maybe door sensors and electric door locks and windows, and the trunk.
It makes much more sense to run the wires through the body pieces of the car since most of those devices the connections are not in the cab of the car but in the body. For example, the switches and motor for the windows are embedded in the door. So the wiring goes from the body to the inside of the door. The tail lights are inside the body of the car, so it makes sense that’s where the wiring is also. In fact, I can’t even think of anything that does run through the body of the car except the cab light.
So why would we run all those wires that are to devices that are mounted to the body parts of the car, inside the cab? The body protects it from most of the elements (except temperature)
