I have a 2014 Ram 2500 with the 6.4 hemi and have been fighting a P2098 code. The other issue is it will misfire randomly and even stop running. I have had a couple shops look at it only to tell me it is an exhaust leak or the O2 sensor is bad, there are no exhaust leaks and I'm not replacing a working O2 sensor based on this code. Am I wrong for thinking the wiring harness for the fuel injectors might be bad?

You can find diagnostic information for that code in the RAM 2500 repair manual:
