Here we have a good used engine bay wiring harness removed from a 2012 gmc 2500hd. This should fit many 11-14 chev and gmc HD trucks with the LML 6.6 engine. This is the harness that runs down to the transmission, NOT the one that sits right on top of the engine. As shown in the photos it is in excellent condition and ready to install. Verify that its the exact part number you need. Sold as shown in the photos. Please email me if you have any questions.
