Harness – GM (86587856)

GM Genuine Parts builds this Harness to the same footprint as the original; the catalogue number is 86587856. In service it carries the factory pinout so the original connectors mate without rewiring. Check the part number stamped or moulded on the original against 86587856 — a number that looks close can belong to a different circuit. GM Genuine Parts are the components installed during production or validated by General Motors for GM vehicles. Held in US stock for same-week dispatch.
