A vehicle seat wiring harness system includes a vehicle seat having a wiring bundle connected to at least an electrical motor energized to displace the vehicle seat and a first fixed point. A wire harness chain is positioned between the first fixed point and a second fixed point connected to a vehicle floor member. The wire harness chain includes multiple links individually including a first connecting wall oppositely positioned with respect to a second connecting wall. A longitudinal cavity is defined between the first connecting wall and the second connecting wall of successive ones of the multiple links. Multiple wires are loosely routed through the longitudinal cavity of the wire harness chain and connected to the wiring bundle.
