Here we have a good used engine bay wiring harness removed from a 2004 GMC 3500hd with the 6.6 Duramax and 4wd transmission. This is the harness that runs around the engine, NOT the one that sits right on the engine and plugs into the injectors. This is used, but removed from a running and driving truck. This will fit 04-05 trucks with the LLY engine ONLY but please compare it to your existing harness plugs to ensure its the one you need, if you need any parts just inquire.
