I have a 2002 2500 that just started the TC lock/unlock. I have been reading this post several times and I have a question. I understand that I need to place the 4 ground wires on the casing but it seems the B+ line is causing a problem due to being routed next to the 5 volt sensor lines. Would changing the B+ line to 2AWG and routing it from the alternator across the top of the radiator and to the 140A fuse at the PDC where it is currently connected fix the issue as well? I would think that that would prevent the battery sensor on main battery and B+ line on alt battery issue. Just a thought.
Thanks
