Here we have a good used engine bay wiring harness removed from a 2004 Chevrolet 2500hd with the 6.6 Duramax and allison 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, may have cosmetic deficiencies or cracked plug ends as shown in the photos. This will fit 03-04 trucks with the LB7 engine ONLY but please compare it to your existing harness plugs to ensure its the one you need, these are non returnable. if you need any parts just inquire.
