The wire harness is all the cables routed throughout the car as well as all the connectors connecting the components. In this position you will need to have a strong and recurring communication with lots of other subsystems that your harness connects to. As well as keeping track of the connections themselves, you will also be involved in placing the different components around the car, as one main concern is keeping wires short. You are expected to design and plan the harness and packaging as the chassis and other system’s designs evolve.
