Here we have a used engine bay wiring harness removed from a 2013 gmc 2500hd. This should fit many 11-14 chev and gmc HD trucks with the LML 6.6 engine. As shown in the photos it is in mostly good condition but does have some minor damage. This is the harness that runs AROUND the engine, not the one that sits right on top. Verify that its the exact part number you need. Sold as shown in the photos. Please email me if you have any questions.
