Yup the harness has chaffing.. I also think that allthough the FICM reads good, it's not in the best shape.. I'm going to get the harness fixed.. If I wans't going to trade it within a couple weeks I would also get the FICM fixed.. I'll fix the wiring and then the 6.0 is going by by.. I have put 9 grand in this truck over the last three years, it's time for me to cut my loses and move on..
