Here we have a complete engine wiring harness for an LMM 6.6 DURAMAX ENGINE. Appears to be in excellent condition with no deficiencies, This harness was removed from a running and driving truck that was in an accident. Should fit all the 08-10 trucks with the LMM engine only. This is for the harness that sits directly on the engine, NOT the harness that go around the engine and down to the transmission.
