I have an 07 5.9L and the motor was recently rebuilt. I am still havign problems with the truck and I ahve reason to believe that most of it is being caused by a faulty PCM wiring harness. Before the motor blew I wasnt having any trouble with it but ever since its been throwing crazy codes, the main connection abouve the intake manifold if broken, and I think its causing over-fueling. The part number for this harness is 68002979AA. If anyone has one, or knows where I can get one, please let me know. Thanks
