OEM engine harness for trucks equipped with a Duramax engine. This is the harness that connects to your injectors and glow plugs, not to be confused with the harness that connects to the ECM / TCM. This harness separates at the buckle connectors on the driver side of the engine.
All harnesses have been removed from running and driving trucks with no issues. Harnesses are used and reflect signs of age and use, such as dirt, oil, and degradation of wire loom.Â
Please be aware of both your engine RPO to select the correct engine harness, and if you have an 2011+ LGH or cab & chassis truck be aware your harness may have variations due to the number of EGRs.
