2017 Polaris 570 EFI 651/5 code problem

Looking for help as I currently own a 2017 sportsman 570 efi everything was running fine and than out of the blue it started bogging down to the point I could not ride it at all. I was able to get the machine to produce a 651/2 code which told me the fuel injector was bad therefore i replaced that and tried to start the machine and received code 651/5. Doing my own research online that was telling me it's the injector harness. I have not found any guide online that shows me a diagram as to where the harness runs to so that i can remove that and replace it. Does anyone have any insight on this situation? I did call the dealer and asked them about the 651/5 code and they were no help to me. Is there a way to test the fuel harness to see if that's actually bad? The only other advice I received was to install the new fuel injector and than unplug the battery to reset the computer? Any thoughts?
