Here we have the wiring harness that goes around the engine and down to the transmission removed from a 2008 2500HD Duramax truck with the 6.6 LMM engine. Excellent condition, with no apparent damage. This is NOT the harness that sits right on top of the engine. This will only fit the 07-10 LMM engines. Please view photos carefully, Make sure this will work for your application BEFORE purchasing.
