Here we have a complete engine wiring harness for an LLY 6.6 DURAMAX ENGINE. This particular harness was removed from a 2005 GMC 2500hd. This should fit all the 04-05 trucks with the LLY engine only. This was removed from a running truck but the harness does show signs of modifications as shown in the photos. This is for the harness that sits directly on the engine, not for the one that runs around the engine.
