F Harness – GM (85703821)

a F Harness from GM Genuine Parts, part 85703821, is a direct replacement for the unit fitted at the factory. It carries the factory pinout so the original connectors mate without rewiring. Match 85703821 to the number on the failed component. Count the pins or check the connector keyway if two numbers look interchangeable. GM Genuine Parts are the components installed during production or validated by General Motors for GM vehicles. Shipped from our US warehouse with tracking.
