Abstract: Systems, methods, and devices providing for the robotic installation of vehicle electrical systems are described. A vehicle wiring harness includes first and second cables, a robotic gripping arm, and at least two pairs of stiffeners coupled to the cables to define folding points and corresponding segments that enable robotic folding and unfolding of the wiring harness. In other examples, a wiring harness is coupled to a plurality of electrical connectors carried by a carrier plate of an electrical control unit connection system (ECU), which is installed by robotically mating the plurality of electrical connectors carried by the carrier plate.
