an Engine Harness from GM Genuine Parts, part 42774345, is a direct replacement for the unit fitted at the factory. The unit carries the factory pinout so the original connectors mate without rewiring. Catalogue application notes: Manual trans, without block heater. Match 42774345 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. Stocked in the US and dispatched within one business day.
